Description

Technical Field

[0001] This utility model relates to the field of building energy conservation technology, specifically an adjustable-angle building external sunshade device. Background Technology

[0002] Building exterior shading devices are functional components installed on the exterior windows or walls of buildings. Their core function is to physically block solar radiation, reduce the amount of direct solar heat entering the room, thereby reducing the building's summer air conditioning energy consumption, improving the indoor lighting environment and avoiding glare, and protecting indoor furniture from the effects of ultraviolet aging. They are an important supporting device for improving building energy conservation and comfort. Currently, the mainstream building exterior shading devices on the market are mainly divided into two categories: one is fixed building exterior shading devices, whose basic structure is usually a rigid panel (such as a metal eaves panel or a concrete baffle panel) fixed to the outside of the building wall or window frame. The panel is directly fixed to the wall embedded parts or window frame by welding or bolts. The other is traditional adjustable building exterior shading devices, whose basic structure is mostly roller type or folding type. Roller type devices usually include a roller mechanism fixed to the wall, flexible shading material (such as shading cloth or thin metal sheet) wound on the roller, and manual or electric components to drive the roller to rotate. Folding type devices consist of multiple rigid shading panels connected in sequence by hinges, and the panels can be folded and unfolded with the help of linear push rods or pull rods.

[0003] Existing building exterior shading devices have significant shortcomings in practical applications, failing to meet the requirements of "flexible angle adjustment and efficient storage to save space": For fixed devices, because their panels are rigidly fixed to the wall, the angle cannot be adjusted according to changes in the solar altitude angle during the season and time of day. This leads to excessive blocking of natural light in spring and autumn, and inability to utilize solar radiation for heating in winter. Furthermore, the devices are always in an extended state and cannot be stored, not only occupying building facade space but also potentially restricting the building's exterior design, making them particularly unsuitable for small apartments or scenarios with strict requirements on the exterior space of walls; for traditional adjustable... Roll-type devices are susceptible to aging and damage due to long-term exposure to wind and rain, and the roll itself still occupies a certain thickness of wall space after being stored, resulting in poor overall structural integrity. While folding devices can achieve a certain angle adjustment, they mostly rely on complex hinge and push rod linkage structures, making installation difficult. Moreover, after being folded and stored, multiple panels stacked together still form a thick protruding structure, making it impossible to fit close to the wall and resulting in low space utilization. In addition, the lack of adjustment hole design leads to insufficient angle adjustment precision, making it difficult to accurately match different shading needs. All of these shortcomings limit the flexibility and spatial adaptability of building exterior shading devices. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing building exterior sunshade devices, such as inconvenient angle adjustment, large storage space occupation, and complex structure, and to provide an adjustable angle building exterior sunshade device that can achieve flexible angle adjustment and efficient storage to save space.

[0005] To achieve the above objectives, this utility model provides an adjustable-angle building exterior sunshade device, including a wall mounting frame for fixing to a building wall, the wall mounting frame having a rectangular frame structure; a sunshade panel assembly having a sunshade panel and an internal frame supporting the panel; and an adjustable support structure composed of multiple connecting rods, each connecting rod having multiple adjustment holes; one end of the adjustable support structure is connected to the wall mounting frame, and the other end is connected to the sunshade panel assembly, the sunshade panel assembly forming a relatively rotatable and angle-adjustable connection with the wall mounting frame through the adjustable support structure, so that the sunshade panel assembly can be unfolded relative to the wall mounting frame to achieve sunshade or retracted to be close to the wall mounting frame.

[0006] The wall-mounted frame is a rectangular hollow frame, with one side for contacting the building wall serving as the mounting surface and the other side for connecting the adjustable support structure and the sunshade assembly. The sunshade assembly has a rectangular panel structure, with an internal frame located on the back of the panel to enhance its structural strength. The internal frame is composed of multiple horizontal and vertical bars connected in a crisscross pattern, forming multiple rectangular grid structures. The adjustable support structure includes at least two connecting rods, one end of which is hinged to the wall-mounted frame, and the other end to the internal frame of the sunshade assembly. Multiple adjustment holes on the connecting rods are evenly distributed along the length of the rods to adjust the connection position between the connecting rods and the wall-mounted frame and the sunshade assembly, thereby changing the tilt angle of the sunshade assembly. In its stowed state, the outer surface of the sunshade assembly's panel is flush with the outer surface of the wall-mounted frame to save space.

[0007] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages compared with the prior art:

[0008] 1. Flexible angle adjustment: Through the design of adjustable support structure connecting rods and adjustment holes, the tilt angle of the sunshade assembly can be precisely adjusted according to the changes in the solar altitude angle, taking into account both sunshade and lighting needs, and improving the comfort of building use;

[0009] 2. Space-saving storage: When stored, the sunshade components can be installed close to the wall frame with no obvious protruding structure, which greatly reduces the space occupied on the building facade and is suitable for a variety of building scenarios;

[0010] 3. The structure is stable and durable, using a rigid wall mounting frame and sunshade assembly, combined with an internal skeleton to enhance support strength. Compared with flexible sunshade materials, it has better wind and rain resistance and a longer service life.

[0011] 4. Easy to install and operate, with a simple overall structure. Connection and angle adjustment are achieved through hinges and adjustment holes, eliminating the need for complex drive components and reducing installation and maintenance costs.

[0012] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figure 1-3 As shown, this utility model discloses an adjustable-angle building exterior sunshade device, including a wall-mounted frame 1, a sunshade assembly 2, and an adjustable support structure 5. The wall-mounted frame 1 is made of aluminum alloy and is a rectangular hollow frame. Its mounting surface is fixed to the building exterior wall by expansion bolts. The installation position corresponds to the outer side of the building's exterior window, ensuring that the sunshade assembly 2 can completely cover the exterior window area after being unfolded. The panel 3 of the sunshade assembly 2 is made of high-strength polycarbonate board and has a rectangular plate structure adapted to the wall-mounted frame 1. An internal skeleton 4 is welded to the back of the panel 3. The internal skeleton 4 is composed of galvanized steel pipe crossbars and vertical bars welded together to form multiple evenly distributed rectangular grid structures, which enhances the wind pressure resistance of the panel 3 and reduces the overall weight. The adjustable support structure 5 includes two stainless steel connecting rods, each with five evenly spaced adjustment holes along its length. One end of the connecting rod is hinged to the hinged ear plate on the outside of the wall mounting frame 1 via a pin, and the other end is hinged to the crossbar of the internal frame 4 via a pin. During adjustment, by disassembling the pin and inserting it into the adjustment holes at different positions, the connection position between the connecting rod and the wall mounting frame 1 and the internal frame 4 can be changed, thereby adjusting the tilt angle between the sunshade assembly 2 and the wall. The angle adjustment range is 0°-60°. 0° corresponds to the retracted state, at which time the outer surface of the panel 3 is completely in contact with the outer surface of the wall mounting frame 1. 60° corresponds to the maximum sunshade angle, which can effectively block direct sunlight at noon in summer. When in use, adjust the angle of the sunshade assembly 2 according to the season or time of day: In summer at noon, insert the connecting rod pin into the outer adjustment hole to tilt the sunshade assembly 2 at 60° for efficient sun shading; in spring and autumn, insert the pin into the middle adjustment hole to keep the angle at 30° to balance sun shading and lighting; in winter or when sun shading is not needed, insert the pin into the inner adjustment hole to allow the sunshade assembly 2 to be stored close to the wall, saving space and utilizing solar radiation for heating.

[0022] Based on the above implementation scheme, this utility model needs to be adjusted according to different implementation needs and the requirements of technical personnel during specific implementation. The following are some reference scenarios:

[0023] Strong sunlight at midday in summer (suitable for ordinary residential PVC windows)

[0024] Existing technology: The building's exterior windows are common 80-series PVC sliding windows, with pre-embedded concrete components on the outer wall of the window frame (compliant with GB50009 Building Structure Load Code). This device's linkage installation: The wall-mounted frame 1 is rigidly connected to the wall-embedded components via M10 expansion bolts, with the installation position corresponding to the full coverage area from the upper to lower edge of the window opening; one end of the two connecting rods of the adjustable support structure 5 is hinged to a pre-embedded stainless steel ear plate on the outer side of the wall-mounted frame 1 (welded to the frame body) via a pin, and the other end is hinged to the crossbar of the internal frame 4 of the sunshade assembly 2; at this time, the connecting rod pin is inserted into the outer adjustment hole, the sunshade assembly 2 is tilted at 60°, the panel 3 completely covers the exterior window glass, and the grid structure of the internal frame 4 disperses wind pressure. Advantages compared to existing technology: Compared to traditional fixed eaves sunshades (which cannot adjust the angle), this device precisely controls the sunshade angle through the adjustment hole, preventing direct sunlight from hitting the glass and causing indoor temperature rise, while not obstructing the sliding opening function of the PVC window.

[0025] Suitable for mild, sunny conditions in spring and autumn (for office building aluminum alloy thermal break windows).

[0026] Existing technology: The exterior window is a 110 series aluminum alloy thermal break window, and the outer wall surface is made of aerated concrete blocks (requiring through-wall bolts for fixation). This device is installed in conjunction with the existing technology: the wall-mounted frame 1 uses through-wall bolts to penetrate the blocks and connect to the internal steel structure keel, ensuring installation strength; the adjustable support structure 5's pin is switched to the central adjustment hole, the sunshade assembly 2's tilt angle is adjusted to 30°, and the panel 3 partially covers the window surface. Structural configuration: The horizontal and vertical crossbars of the internal frame 4 are reinforced with angle brackets, and combined with the polycarbonate material of the panel 3, it filters strong light to avoid glare while retaining natural light; nylon wear-resistant pads are installed at the hinges between the connecting rods and the wall-mounted frame 1 to reduce wear during adjustment. Advantages compared to existing technologies: Compared to roller sunshades (where the flexible fabric is easily blown by the wind and obstructs window opening), this device's rigid panel and adjustable connecting rods do not affect the inward opening and tilting function of the aluminum alloy window, and the grid-like frame enhances wind resistance stability.

[0027] Winter scenarios requiring no sunshade (suitable for steel exterior windows in older residential areas)

[0028] Existing Technology: The exterior window is an old-style steel hollow window with no embedded parts on the outer wall, requiring reinforcement with chemical anchors. This device's linkage installation: The wall mounting frame 1 is connected to the brick wall via M8 chemical anchors. The pin of the adjustable support structure 5 is inserted into the inner adjustment hole. The sunshade assembly 2 is fully retracted, and the outer surface of the panel 3 is flush with the outer surface of the wall mounting frame 1, with a gap ≤5mm. Structural states: The internal frame 4 is flush with the back of the panel 3, not protruding from the wall; the connecting rod is in a retracted state, with the hinge point with the wall mounting frame 1 at its minimum opening angle. Advantages compared to existing technology: Compared to folding sunshades (where multiple panels overlap and protrude ≥150mm after retraction), this device occupies almost no exterior space after retraction, avoiding scratches to pedestrians. It also does not affect the hand-cranked opening mechanism of the steel window, and the wall-hugging design reduces cold air penetration in winter.

[0029] Extreme weather scenarios such as typhoons and heavy rain (suitable for thermally broken aluminum exterior windows in coastal areas)

[0030] Existing Technology: The exterior windows are thermally broken aluminum windows with a wind pressure resistance rating of ≥5, and the exterior wall is a reinforced concrete shear wall. This device is installed in conjunction with the wall: The rectangular hollow frame of the wall mounting frame 1 is fully connected to the shear wall using expansion bolts (bolt spacing ≤300mm). The connecting rod pins of the adjustable support structure 5 are inserted into the inner adjustment holes, and the sunshade assembly 2 is stowed and fitted against the wall. The horizontal and vertical bars of the internal frame 4 are made of thickened galvanized steel pipes (wall thickness ≥2.5mm), with welded reinforcement at the joints. Structural Status: The panel 3 is tightly connected to the internal frame 4 using self-tapping screws, with no loose gaps. A waterproof sealing strip is installed between the wall mounting frame 1 and the wall to prevent rainwater from seeping into the wall. Advantages of Integrating with Existing Technology: Compared to traditional outdoor sunshades (which need to be disassembled during typhoons), this device, through its rigid structure and strong connection to the wall, and its low wind resistance design in the stowed state, can withstand typhoons below level 10, requires no temporary disassembly, and does not affect the rainwater drainage system of the exterior windows.

[0031] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
