Description

Technical Field

[0001] This application relates to the field of building shading, and in particular to a foldable building shading device. Background Technology

[0002] In the construction industry, shading devices have always been an important component. With the continuous development of the construction industry, people's needs for building shading are becoming increasingly diversified. Shading devices can not only regulate indoor light intensity, reduce indoor temperature, and decrease energy consumption of equipment such as air conditioners, but also enhance the aesthetics and comfort of buildings. Good shading design can improve the indoor thermal environment, creating more pleasant living and working spaces for people, while also aligning with the environmental protection concept of energy conservation and emission reduction, and playing a significant role in promoting the development of green buildings.

[0003] Traditional architectural shading techniques commonly include installing fixed sunshades. These sunshades are typically designed and installed according to the building's orientation and local sunlight conditions, and their angle and position remain largely fixed after installation. Another method is using blackout curtains, which are controlled manually or electrically to achieve shading. Additionally, Venetian blinds are a frequently used shading method, allowing users to control the amount of light entering by adjusting the angle of the blinds. These methods, to a certain extent, meet the needs of architectural shading and are widely used in various types of buildings.

[0004] However, existing architectural shading devices have certain limitations. Traditional fixed sunshades have fixed angles and positions, making them unable to be flexibly adjusted according to different seasons, times, and sunlight angles, resulting in limited shading effectiveness. Sunshade curtains and blinds take up space when not in use and are prone to damage and aging after prolonged use, affecting their lifespan and shading effect. Furthermore, most of these devices lack folding functionality, making them inconvenient to transport and install. Summary of the Invention

[0005] The purpose of this application is to overcome the aforementioned technical problems and provide a foldable building sunshade device. To achieve the above objectives, the present invention adopts the following technical solution: a foldable building sunshade device, comprising two support columns, the top ends of which are respectively provided with a first fixing ring and a second fixing ring. The first fixing ring is provided with a plurality of fixing holes. A rotating shaft is provided inside the first fixing ring, connected to the second fixing ring and extending to the outside of the first fixing ring. The rotating shaft is rotatably configured with the first fixing ring and the second fixing ring. A positioning plate is provided on the rotating shaft located outside the first fixing ring. The positioning plate is provided with a positioning hole and a positioning rod. The size and position of the positioning hole correspond to the fixing hole. A first sunshade plate is provided on the rotating shaft. A second sunshade plate is hinged to the first sunshade plate. A limit block is provided on the side of the first sunshade plate near the second sunshade plate. A third sunshade plate is slidably configured inside the second sunshade plate.

[0006] Preferably, the second sunshade has a groove on its side, and a sliding block connected to the third sunshade is provided in the groove.

[0016] The technical solutions in the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of the present invention without creative effort are also within the protection scope of the present invention.

[0017] This application mainly adopts a foldable sunshade panel combined with a rotating shaft and support column, which achieves the effect of flexible sunshade and convenient transportation and installation. The following is a further detailed description of this application.

[0018] Example 1 The foldable building sunshade device provided in this application embodiment includes a support column 1, a rotating shaft 5, and a sunshade assembly. The support column 1 has a fixed ring at its top, the rotating shaft 5 passes through the fixed ring and can rotate, and the sunshade assembly is installed on the rotating shaft 5, achieving the effect of flexibly adjusting the sunshade angle and being foldable. This is because the rotating shaft 5 can rotate, allowing the sunshade to adjust its angle, and the hinge and sliding structure of the sunshade assembly makes it foldable.

[0019] Specifically, support column 1 includes two retractable support columns, with a base 15 at the bottom. The retractable support columns typically employ a multi-section nested sleeve structure, and can be made of high-strength aluminum alloy, which is lightweight and strong, or stainless steel, which is more corrosion-resistant. The base 15 is usually flat and can be made of cast iron for good stability, or plastic for lower cost. The base 15 is fixed to the support column 1 by welding or bolting to ensure the stability of the entire device.

[0020] The tops of the two support columns 1 are respectively equipped with a first fixing ring 2 and a second fixing ring 3. Generally, the fixing rings are made of metal materials, such as carbon steel, and are manufactured through machining processes such as turning. The first fixing ring 2 has no fewer than four fixing holes 4, which are machined by drilling and are used to mate with the positioning holes 7 on the positioning plate 6. A rotating shaft 5 is provided inside the first fixing ring 2, connecting to the second fixing ring 3 and extending outside the first fixing ring 2. The rotating shaft 5 is usually cylindrical and can be made of alloy steel to ensure sufficient strength and rigidity. The rotating shaft 5 is rotatably connected to the first fixing ring 2 and the second fixing ring 3 via bearings. Deep groove ball bearings can be used, which have good rotational performance.

[0021] A positioning disc 6 is located outside the first fixed ring 2 on the rotating shaft 5. The positioning disc 6 is generally a circular metal disc, made of a material similar to the rotating shaft. The positioning disc 6 has a positioning hole 7 and a positioning rod 8. The positioning hole 7 corresponds to the size and position of the fixing hole 4. The positioning rod 8 can be inserted into the positioning hole 7 and the fixing hole 4 to position the rotating shaft 5. When it is necessary to adjust the sunshade angle, the positioning rod 8 is pulled out, the rotating shaft 5 is rotated to the appropriate position, and then the positioning rod 8 is inserted into the corresponding positioning hole 7 and the fixing hole 4 to complete the positioning.

[0022] A first sunshade 9 is mounted on the rotating shaft 5. The first sunshade 9 is generally a rectangular plate structure, made of either plastic (low cost and lightweight) or aluminum (good heat dissipation). A second sunshade 10 is hinged to the first sunshade 9. The hinge is typically made of stainless steel, which is durable and rust-resistant. A limit block 11 is located on the side of the first sunshade 9 closest to the second sunshade 10. The limit block 11 is generally a block of rubber or plastic, and its function is to limit the rotation angle of the second sunshade 10.

[0023] A third sun visor 12 is slidably disposed inside the second sun visor 10. A groove 13 is provided on the side of the second sun visor 10, which is generally machined by milling. A sliding block 14, which can be a plastic or metal block, is disposed within the groove 13 and connects to the third sun visor 12. The sliding block 14 is clearance-fitted with the groove 13 to ensure smooth sliding. The sliding of the sliding block 14 within the groove 13 enables the extension and retraction of the third sun visor 12 within the second sun visor 10.

[0024] Solar panels are installed on the first sunshade 9 and the second sunshade 10. These solar panels convert sunlight into electricity to power small devices such as lighting equipment. The solar panels are typically installed on the sunshades using adhesive or bolts. The side surfaces of the support column 1 and the third sunshade 12 are covered with a corrosion-resistant and UV-resistant transparent film. This film protects the support column 1 and the third sunshade 12 from UV rays and corrosive substances, extending their service life. The film is generally applied to the surfaces of the support column 1 and the third sunshade 12 using a lamination process.

[0025] The implementation principle of this embodiment is as follows: The foldable building sunshade device ensures the stability and adjustability of the device through the telescopic support column 1 and the base 15. The setting of the rotating shaft 5 and the positioning plate 6 allows the sunshade panel to be flexibly adjusted according to different seasons, times, and light angles, improving the sunshade effect. The hinged and sliding structure of the sunshade panel allows it to be folded, reducing space occupation when not in use and making transportation and installation more convenient. The setting of the solar panel realizes energy recycling and utilization, which is in line with the environmental protection concept of energy conservation and emission reduction. The use of corrosion-resistant and UV-resistant transparent film extends the service life of the device. Compared with traditional building sunshade devices, this device has better flexibility, convenience, and durability, and solves the limitations of existing sunshade devices.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
