Description

Technical Field

[0001] This utility model relates to the field of sunshade technology, specifically to a forward-facing and sealing combination structure for protecting sunshades. Background Technology

[0002] Awnings primarily serve to shelter people from wind and rain, while also providing sun protection and decoration. They are commonly used in houses, street-front shops, and scenic areas. As commercial products, awnings utilize a motor to rotate an aluminum alloy roller, causing the fabric wound on the roller to rise and fall. Simultaneously, springs within the support arms keep the fabric taut. With the widespread use of awnings for sun and rain protection, their forms have become increasingly diverse.

[0003] The awning has comprehensive external shading function, which can completely block ultraviolet radiation, reduce indoor temperature, reduce air conditioning load, and has energy-saving effect. Moreover, while blocking the hot summer sun, it can reflect strong sunlight into the room in the form of diffused light, making the indoor light bright but not dazzling. Summary of the Invention

[0004] This utility model primarily addresses the shortcomings of existing technologies by providing a combined structure for the front-end and cover of a sunshade awning. It is characterized by ease of use, simple operation, and good stability. A screw drive mechanism enables the front-end to automatically unfold and retract the sunshade fabric. This achieves the function of sunshade and rain protection, while also being convenient to extend and retract, and easy to assemble. It is a practical and widely applicable sunshade and rainproof awning.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0006] A combined structure for protecting a sunshade, comprising a sunshade fabric retractor box, with sealing guide rails on both sides of the front end of the retractor box, a forward-facing device positioned between the two sealing guide rails, and a sunshade fabric positioned between the retractor box and the forward-facing device. Each of the sealing guide rails is equipped with a sunshade fabric opening and closing component that drives the forward-facing device to unfold or retract the sunshade fabric. The sunshade fabric opening and closing component includes a lead screw, a slider mounted on the lead screw, and a connecting block between the slider and the side of the forward-facing device.

[0007] Preferably, the sunshade cloth rewind box is equipped with a screw motor on both sides to drive the screw to rotate and move the slider. The front end of the screw motor is equipped with a bearing seat, and the other end of the drive screw is equipped with a stop plate that is fixedly connected to the cover guide rail.

[0008] Preferably, the rear end of the sunshade fabric rewind box is provided with a mounting plate for fixing the sunshade fabric rewind box and the lead screw motor.

[0009] Preferably, the front end of the sunshade fabric take-up box is provided with a take-up guide S-plate for guiding the sunshade fabric.

[0010] This invention can achieve the following effects:

[0011] This utility model provides a combined structure for the front and cover of a sunshade awning, which, compared with existing technologies, is convenient to use, simple to operate, and has good stability. A screw drive mechanism enables the front to automatically unfold and retract the sunshade fabric. It achieves the function of sunshade and rain protection, while being easy to extend and retract, and easy to assemble. It is a practical and widely applicable sunshade and rainproof awning.

[0012] High-precision control: It adopts a ball screw drive, which ensures smooth movement and high positioning accuracy, making it suitable for occasions that require precise control of the unfolded length.

[0013] Compact structure: The lead screw motor, bearing housing, stop plate, etc. are all integrated between the cover guide rail and the winding box, resulting in a compact overall structure and small space occupation.

[0014] High reliability: The lead screw and slider work together to prevent slippage, resulting in high transmission efficiency and long service life. The stop plate design effectively prevents axial movement of the lead screw, improving operational stability.

[0015] Good protection: The combination of forward-looking and cover rails forms effective protection for the sunshade cloth, avoiding wear and tear or contamination caused by wind and sun exposure.

[0016] Easy to maintain: Modular design, with each component relatively independent, making it easy to inspect and replace. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] Example: Figure 1 and Figure 2As shown, a combined structure for protecting a sunshade, comprising a sunshade fabric retractor 4, with sealing guide rails 1 on both sides of the front end of the retractor 4, a front end 7 between the two sealing guide rails 1, and a sunshade fabric 6 between the retractor 4 and the front end 7. A retracting guide S-plate 5 for guiding the sunshade fabric 6 is located at the front end of the retractor 4. Each sealing guide rail 1 is equipped with a sunshade fabric opening / closing assembly 2 that drives the front end 7 to unfold or retract the sunshade fabric 6. The sunshade fabric opening / closing assembly 2 includes a lead screw 9, a slider 10 on the lead screw 9, and a connecting block 11 between the slider 10 and the side of the front end 7. Both sides of the retractor 4 are equipped with lead screw motors 13 that drive the lead screw 9 to rotate and move the slider 10. The front end of the lead screw motor 13 is equipped with a bearing seat 8, and the other end of the lead screw 9 is equipped with a stop plate 12 fixedly connected to the sealing guide rail 1. The rear end of the sunshade fabric rewind box 4 is provided with a mounting plate 3 for fixing the sunshade fabric rewind box 4 and the lead screw motor 13.

[0022] Working principle:

[0023] Unfolding process

[0024] Start the motor: Start the lead screw motor 13, which drives the lead screw 9 to rotate.

[0025] Slider movement: The rotation of lead screw 9 drives slider 10 to move along the lead screw axis.

[0026] Linked look-ahead: Slider 10 drives look-ahead 7 to move synchronously through connecting block 11.

[0027] Shade fabric unfolding: The forward-looking 7 moves forward, pulling the shade fabric 6 out of the roll-up box 4. At the same time, the roll-up guide S plate 5 guides the fabric to ensure a smooth unfolding process without jamming.

[0028] Rewinding process

[0029] Motor reversal: The lead screw motor 13 rotates in the opposite direction, and the lead screw 9 rotates in the opposite direction accordingly.

[0030] Slider return: Slider 10 moves in the opposite direction along the lead screw, causing the forward look-ahead 7 to move backward.

[0031] Shade fabric rewinding: The shade fabric 6 is automatically rewound in the rewind box 4. The guide plate S5 also plays a guiding role to prevent the fabric from shifting or rolling up.

[0032] In summary, this combined structure of the canopy and cover for providing protection against the sunshade is characterized by its ease of use, simple operation, and good stability. The canopy automatically unfolds and retracts the sunshade fabric via a screw drive mechanism. It achieves the function of sunshade and rain protection, while being easy to extend and retract, and convenient to assemble. It is a practical and widely applicable sunshade and rainproof canopy.
