Description

Technical Field

[0001] This invention relates to the field of sunshade technology, and in particular to a connection structure for a large sunshade. Background Technology

[0002] Existing sunshades are generally made of materials that provide sun protection, such as glass, metal, wood, terracotta, and ceramics, and consist of connecting frames and metal components. When electric control is required, they should also include motors, wiring, and sensor linkage devices. They are commonly used for external sunshades of public and industrial buildings. However, in the current technology, sunshades are generally fixed to the exterior walls of buildings through connectors. The sunshades cannot change with the sun's altitude. When the sun is high, the sunshade can block most of the sunlight, but when the sun is low, the sunshade effect is significantly reduced. Therefore, there is an urgent need for a sunshade that can adjust the angle.

[0003] A prefabricated steel structure sunshade, disclosed in Chinese patent literature (publication number CN217299550U, publication date 2022-08-26), includes two bases, several support components, a sunshade cloth, and locking components. The bases have two vertical plates arranged parallel to each other, with a groove between them. The groove contains an elongated slot. The top plate of each vertical plate has a horizontal plate with elongated holes corresponding to the elongated slots. The support components include two sliders, two telescopic rods, and a support rod. The sliders are respectively located in the grooves of the two bases, and the two telescopic rods are respectively located on the two sliders. The two ends of the support rods are respectively connected to the two telescopic rods. The sunshade cloth is supported on the support assembly through the adjacent support rods. The sliders have through holes on both sides, and the locking piece can pass through the elongated hole, the elongated hole, and the elongated groove simultaneously, fixing and locking the slider to the base and restricting the movement of the support assembly. When the locking piece is loose, the support assembly can slide in the groove, allowing several support assemblies to adjust the sunshade cloth between the unfolded and retracted states. Although this sunshade can drive the unfolding and retraction of the sunshade components through the sliding of the support assemblies, it cannot directly adjust the angle of the sunshade components. Summary of the Invention

[0004] The present invention aims to overcome the problem that large sunshade components installed on building walls in the prior art cannot be angled. It provides a connection structure for large sunshade components, in which the top plate assembly and the bottom plate assembly are rotatably connected to form a hinge-like assembly. The top plate assembly and the bottom plate assembly are fixed to the support part by rotatable top connecting assembly and bottom connecting assembly, which can realize the angle adjustment of the sunshade component within a set range.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A connection structure for a large sunshade includes a top plate assembly, one end of which is rotatably connected to one end of a bottom plate assembly, the other end of which is fixedly connected to one end of a top connecting assembly, and the other end of which is rotatably connected to a support portion; the other end of the bottom plate assembly is fixedly connected to one end of a bottom connecting assembly, and the other end of which is connected to the support portion.

The top plate assembly is connected to the support via a top connecting component, and the bottom plate assembly is connected to the support via a bottom connecting component. The top connecting component can rotate about its connection point with the support, thus rotating the top plate assembly relative to the bottom plate assembly to adjust the angle of the sunshade. Furthermore, the bottom connecting component can also adjust the angle of the bottom plate assembly by adjusting its angle with the support. Combined with the angle adjustment of the top plate assembly relative to the bottom plate assembly, different sunshade angles and effects can be achieved. In this invention, the support is not a specific wall; the top and bottom connecting components can connect the sunshade to different building exterior walls, achieving angle adjustment in all cases, thus broadening its applicability.
