Description

Technical Field

[0001] This utility model relates to the field of sunshade technology, specifically to a draped square shell structure for a full-box curved arm sunshade. Background Technology

[0002] Retractable awnings are a type of telescopic awning, utilizing aluminum alloy retractable arms and a spring system to achieve their telescopic function. The frame's adjustable angle range is 8-70 degrees. Its structure consists of an awning fabric, an aluminum roller, a power mechanism, and aluminum alloy retractable arms. The fabric is typically made of polyester or acrylic. The outer frame comes in two forms: semi-box and full-box. Originating in Europe and America, this product has a century-long history of application. The control system supports manual, electric, and remote control operation and is equipped with wind, light, and rain sensors for automatic retraction in inclement weather.

[0003] The domestic retractable arm awning industry is in its early stages of development, with width specifications ranging from 2 to 6 meters, unfolded width from 1.5 to 3 meters, and a maximum applicable extension length of 4 meters. Power mechanisms include tubular motors and gearboxes, and installation scenarios cover villas, hotels, and commercial plazas. Some products achieve height adjustment through telescopic drive cylinders and guide rail structures, using high-strength aluminum alloy or steel as the frame material.

[0004] Currently, awnings in architectural leisure products are generally fixed, meaning they are fixed to the building using fixed brackets, and the canopy is installed on the fixed brackets. The disadvantages of this type of awning are:

[0005] 1. Regardless of the weather or whether shade is needed, the tarpaulin must not be retracted.

[0006] 2. Long-term exposure to wind and sun causes significant erosion to the canopy and its mounting frame, resulting in a shorter lifespan and affecting indoor lighting. Summary of the Invention

[0007] This invention primarily addresses the shortcomings of existing technologies by providing a fully enclosed square shell structure for a retractable arm sunshade. This fully enclosed square shell mainly houses and protects the internal retractable arms, canopy roll tubes, and guide system. It solves three core problems related to the ease of installation, structural stability, and product durability of sunshades. It simplifies complex alignment and load-bearing issues, significantly reducing the difficulty and labor intensity of on-site installation.

[0008] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0009] A rectangular outer shell structure for a full-frame retractable arm sunshade includes a shell with a front panel at the front end. Inside the shell are a pair of telescopic arms symmetrically arranged in a mirror pattern. One end of each telescopic arm is fixedly connected to the shell, and the other end is fixedly connected to the front panel. The extension and retraction of the telescopic arms move the front panel and the canopy fabric, thus opening and closing the sunshade. End caps are provided at both ends of the shell, and assembly blocks are provided on both sides of the rear end. The shell includes a rear protective plate. A lower bottom plate, which is inserted into the lower end of the rear protective plate, is connected to the upper end of the rear protective plate, which is also inserted into the upper end. The front panel, rear protective plate, upper top plate, and lower bottom plate together form a rectangular outer shell structure.

[0010] Preferably, an arm connecting seat is provided between the telescopic arm and the rear guard plate, which is pin-connected and fixed to the telescopic arm; an inner support block is provided between the two telescopic arms, which is snap-fitted and fixed to the rear guard plate; and a canopy guide plate is provided between the arm connecting seat and the inner support block.

[0011] Preferably, the cross-section of the canopy guide plate is S-shaped. When the awning is retracted, the canopy fabric needs to be neatly wound onto the rear roller. The S-shaped structure can smoothly guide the canopy fabric from a horizontal state (when unfolded) to a vertical winding state (when retracted), preventing the canopy fabric from being pinched, wrinkled, or shifted, ensuring a flat roll-up, and extending the life of the canopy fabric.

[0012] Preferably, the rear guard plate and the assembly block are provided with an external support seat that is inserted and snapped into the assembly block.

[0013] Preferably, the outer support base has an "L" shaped cross-section, and the outer support base plays a role in fixing and supporting the connection structure of the rear guard plate and the lower base plate.

[0014] Preferably, the upper part of the lower part of the forward-looking plate is provided with a pressing rod that is snapped into the forward-looking plate, and the two ends of the pressing rod are provided with pressing rod fixing seats that are screwed to and fixed to the forward-looking plate and inserted into the pressing rod.

[0015] Preferably, the upper top plate is provided with a baffle extending downwards from the assembly block, and the baffle is fixedly inserted into the upper top plate.

[0016] Preferably, the two ends of the housing are provided with sealing plates that are screwed and fixed to the end caps.

[0017] This invention can achieve the following effects:

[0018] This invention provides a square outer shell structure for a fully enclosed curved arm sunshade. Compared with existing technologies, it adopts a fully enclosed square shell, whose main function is to accommodate and protect the internal curved arms, canopy roll tubes, and guide system. It solves three core problems related to the ease of installation, structural stability, and product durability of sunshades. It simplifies complex alignment and load-bearing issues, greatly reducing the difficulty and labor intensity of on-site installation.

[0019] Modular design for convenient and efficient installation: The outer shell is composed of multiple interlocking panels (rear guard plate, top plate, and bottom plate), and most internal components are also fixed by snap-fit ​​or screws, facilitating production and assembly. In particular, the "hook-on" design of the external support base and assembly block simplifies complex alignment and load-bearing issues, greatly reducing the difficulty and labor intensity of on-site installation.

[0020] Multiple reinforcements ensure structural stability and reliability: The designers fully considered the stress issues and implemented multiple reinforcement structures.

[0021] Internal reinforcement: internal support blocks resist internal torsional forces.

[0022] External reinforcement: External support bases resist external tensile forces and gravity, which is the core guarantee for structural stability.

[0023] Reinforced connection: The pin connection of the arm connector ensures the flexibility of movement.

[0024] Meticulous attention to detail enhances product quality and lifespan.

[0025] Waterproof design: The design of the baffle reflects a deep consideration of the problems that the product may encounter during long-term outdoor use (rainwater seepage).

[0026] Guiding protection: The "S"-shaped canopy guide plate effectively protects the canopy from wear and tear during the opening and closing process, which is a key detail to improve the product's durability.

[0027] Combining aesthetics and practicality: The full-box square outer shell is not only beautiful, but also provides maximum protection for the internal precision mechanism from wind, sun and rain. Attached Figure Description

[0034] Workflow:

[0035] Deployment: The telescopic arm 10 is slowly extended forward by a motor or hand crank. The telescopic arm pushes the forward-facing panel 7 forward, while the canopy is released from the roll tube. The canopy unfolds smoothly under the guidance of the canopy guide plate 15. The inner support block 6 ensures the stability of the rear protective panel 8, while the outer support base 3 firmly supports the entire shell, resisting the enormous tensile force generated by the extension.

[0036] Retraction: The drive unit reverses its operation, the telescopic arm 10 retracts, and the forward-looking plate 7 moves backward. The canopy fabric is retracted and neatly wound onto the roll tube under the guidance of the canopy fabric guide plate 15. The pressing rod 16 presses the front end of the canopy fabric tightly against the forward-looking plate 7 to ensure compactness when retracted.

[0037] In summary, the draped square shell structure of this fully enclosed awning primarily houses and protects the internal curved arms, canopy roll tubes, and guide system. It solves three core problems related to awning installation convenience, structural stability, and product durability. By simplifying complex alignment and load-bearing issues, it significantly reduces the difficulty and labor intensity of on-site installation.
