Abstract
Description
Technical Field
[0001] This utility model relates to the field of awning technology, and in particular to a retractable awning. Background Technology
[0002] Retractable awnings are commonly used outdoor sunshade and rain protection devices, widely applied in shop entrances, open-air leisure areas, courtyards, and temporary event venues. They can be expanded or retracted as needed, providing shelter for users while saving space when not in use. They are characterized by easy installation and flexible use.
[0003] Existing retractable awnings mostly employ a spring-loaded unfolding structure. Their basic working principle is as follows: both ends of the awning are connected to the ends of a spring assembly. A drive mechanism moves one end of the awning along a slide rail, causing the awning to fold and compress the spring assembly when retracted, thus storing elasticity. When the awning needs to be unfolded, the spring assembly releases the stored elasticity, opening the two ends of the awning and allowing it to unfold smoothly along the slide rail, achieving its shading function. However, existing technology has significant shortcomings. This type of structure relies on springs pulling the two ends of the awning to complete the unfolding, while the middle section mainly relies on the guiding effect of the slide rail. In actual use, due to friction and resistance as the bottom of the middle section moves along the slide rail, the unfolding in the middle is often uneven. This can cause a depression on the top surface of the middle section of the awning, which easily accumulates water, especially during rain. Long-term water accumulation not only affects the drainage effect of the awning but also increases the pressure on the tarpaulin, easily causing damage to the tarpaulin, reducing the lifespan of the awning, and even posing safety hazards. Utility Model Content
[0004] The technical problem this utility model aims to solve is: to address the issue of uneven expansion in the middle of the canopy, which leads to a depression on the top surface of the middle of the canopy and makes it prone to water accumulation.

One end of the pull rope is attached to the drum of the winch, and the other end of the pull rope is attached to the second end of the diamond-shaped telescopic frame. When the winch retracts the length of the pull rope, the second end of the diamond-shaped telescopic frame folds towards the first end of the diamond-shaped telescopic frame.

The first pulley and the second pulley are slidably disposed on the upper slide rail and the lower slide rail, respectively, and the rhomboid frame is located between the upper slide rail and the lower slide rail.
[0009] Furthermore, the two rhomboid telescopic frames are arranged symmetrically to each other, and a transverse connecting rod is provided between the top ends of the two symmetrical support rods in the two rhomboid telescopic frames, and the transverse connecting rod is connected to the bottom surface of the tarpaulin.
[0010] Furthermore, the top ends of the two symmetrical support rods in the two rhomboid telescopic frames are integrally formed with the transverse connecting rod.
[0011] Furthermore, the upper side of the rhombus frame is connected to the lower side of another adjacent rhombus frame, and the lower side of the rhombus frame is connected to the lower side of another adjacent rhombus frame.

[0013] Furthermore, the bottom end of the rhomboid frame is provided with a third pulley or slider, which is slidably mounted on the slide rail.
[0014] Furthermore, it also includes a base, an equipment compartment, and a roller shutter door. The canopy frame is mounted on the base, and the equipment compartment and the roller shutter door are respectively mounted on the top two ends of the base, with the equipment compartment and the roller shutter door located below the tarpaulin.
[0015] Compared with the prior art, the retractable awning provided by this utility model has the following advantages: By setting springs in a stretched state along the vertical diagonal of the top and bottom diagonal hinge points of the rhombus frame, when the springs contract, their vertical retraction will shorten the rhombus frame longitudinally and extend it laterally. The rhombus telescopic frame formed by multiple series of rhombus frames can thus extend evenly along the slide rail, thereby driving the awning installed on the telescopic frame to unfold smoothly as a whole.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0023] like Figures 1 to 6 As shown in the figure, this utility model embodiment discloses a retractable awning, including: an awning frame 1, which is provided with two slide rails 11; two rhomboid retractable frames 2, which are slidably mounted on the two slide rails 11 respectively. Each rhomboid retractable frame 2 includes a spring 22 and a plurality of rhomboid frames 21 connected end to end. The rhomboid frames 21 are slidably mounted on the slide rails 11. The ends of two adjacent sides of the rhomboid frames 21 are hinged. The two diagonals of the rhomboid frames 21 are respectively set vertically and horizontally. Two adjacent rhomboid frames 21 are connected by a diagonal connection at the middle. The spring 22 is set on the rhomboid frames 21 along the vertical diagonal. The two ends of the spring 22 are respectively connected to the top diagonal hinge point and the bottom diagonal hinge point of the rhomboid frames 21. The spring 22 is in a stretched state; and a rain tarp 3, which is mounted on the two rhomboid retractable frames 2 on both sides of its bottom surface.
[0024] The retractable awning of this application uses springs 22 in a stretched state installed diagonally along the vertical direction at the top and bottom diagonal hinge points of the rhombus frame 21. When the springs 22 contract, their vertical retraction will shorten the rhombus frame 21 longitudinally and extend it laterally. The rhombus retractable frame 2 formed by multiple series of rhombus frames 21 can thus extend evenly along the slide rail 11 at equal intervals, thereby driving the awning installed on the retractable frame to unfold smoothly as a whole. This effectively avoids the problem of uneven unfolding in the middle of the traditional retractable awning, which causes the top surface to sink and water to accumulate. It achieves uniform unfolding and reliable drainage of the awning, and significantly improves the stability and durability of the awning.
[0025] By setting two slide rails 11 on the canopy frame 1, and arranging diamond-shaped telescopic frames 2 on the two slide rails 11 respectively, and fixing the two sides of the tarpaulin 3 to the diamond-shaped telescopic frames 2, the canopy is synchronously driven by the diamond-shaped telescopic frames 2 when it is opened and closed, thus ensuring the uniformity of the overall opening of the canopy. The diamond-shaped telescopic frame 2 is composed of multiple diamond-shaped frames 21 connected in series, with adjacent diamond-shaped frames 21 connected by hinges, and springs 22 in a stretched state are set on the diagonal. When the canopy is closed, the springs 22 are further stretched and store energy. When the canopy is opened, the springs 22 contract under the action of tension, driving each diamond-shaped frame 21 to extend laterally, so that the entire diamond-shaped telescopic frame 2 can be opened at equal intervals. This can effectively avoid the problem of the central top surface sinking caused by traditional telescopic canopies that rely only on the pull at both ends, thereby eliminating the hidden danger of rainwater accumulation in the middle, improving the stability and drainage performance of the canopy, extending its service life, and improving the overall safety and user experience.
[0026] Specifically, the rhombus frame 21 has two mid-diagonal sections on the same horizontal line, and top and bottom diagonal sections on the same vertical line. The beginning and end of the rhombus frame 21 are the two mid-diagonal sections, respectively. The spring 22 is set on the rhombus frame 21 along the vertical diagonal, and its two ends are connected to the top and bottom diagonal hinge points of the rhombus frame 21, respectively. Adjacent sides of the rhombus frame 21 are connected by hinges. The two rhombus telescopic frames 2 are located on both sides below the bottom surface of the tarpaulin 3.
[0027] Specifically, the canopy frame 1 is equipped with a motor that drives the diamond-shaped telescopic frame 2 to move along the slide rail 11. The slide rail 11 is a strip-shaped groove, and the bottom end of the diamond frame 21 is provided with a pulley or slider, which is slidably mounted on the slide rail 11.
[0028] like Figure 1 and Figure 4 As shown, in an optional embodiment of the utility model, the telescopic awning of this application further includes a winch 4 and a pull rope 5. The winch 4 is located at the first end of the diamond telescopic frame 2. One end of the pull rope 5 is set on the drum of the winch 4, and the other end of the pull rope 5 is set on the second end of the diamond telescopic frame 2. When the winch 4 retracts the length of the pull rope 5, the second end of the diamond telescopic frame 2 folds towards the first end of the diamond telescopic frame 2.
[0029] By installing a winch 4 at one end of the diamond-shaped telescopic frame 2 and connecting it to the other end of the frame using a pull rope 5, the winch 4 actively drives the second end of the diamond-shaped telescopic frame 2 to fold towards the first end when the pull rope 5 is retracted. This makes the retraction process of the canopy smoother and more controllable. Compared with the traditional method of relying on a motor to drive retraction, this structure achieves efficient retraction without a complex motor mechanism, requiring less effort to operate, reducing energy consumption and equipment failure risks, while also reducing maintenance costs and improving the reliability and durability of the canopy retraction system. Furthermore, the drive mechanism of the winch 4 makes the retraction of the canopy more effortless and convenient, especially suitable for the unfolding and retraction of large-sized canopies, further enhancing the reliability and durability of the canopy.
[0030] like Figure 3 and Figure 6 As shown, in an optional embodiment of the utility model, the rhomboid frame 21 is provided with a support rod 23 in the vertical direction. The support rod 23 is connected to the diagonal hinge point of the rhomboid frame 21. The support rod 23 is provided with a pulley, which is slidably mounted on the slide rail 11. The support rod 23 is connected to the bottom surface of the tarpaulin 3.
[0031] By adding support rods 23 to the rhomboid frame 21 and installing pulleys on the support rods 23, the pulleys can slide smoothly along the slide rail 11, further enhancing the guiding and supporting role of the rhomboid telescopic frame 2 during the opening and closing of the canopy. The support rods 23 are connected to the bottom surface of the tarpaulin 3, which not only effectively distributes the force on the tarpaulin 3, preventing localized suspension or sagging during unfolding, but also maintains the synchronous movement of the bottom surface of the tarpaulin 3 and the telescopic frame, thus ensuring the flatness and stability of the canopy during unfolding. This support rod 23 structure improves the overall load-bearing capacity and wind resistance of the canopy, reduces the risk of water accumulation due to sagging of the tarpaulin 3, extends the service life of the tarpaulin 3, and enhances the safety and durability of the canopy. Specifically, the bottom sides of the tarpaulin 3 are respectively mounted on the support rods 23 of the two rhomboid telescopic frames 2.
[0032] like Figure 1 and Figure 5 As shown, in an optional embodiment of the utility model, the slide rail 11 includes an upper slide rail 111 and a lower slide rail 112, and the pulleys include a first pulley 231 and a second pulley 232. The first pulley 231 and the second pulley 232 are respectively slidably disposed on the upper slide rail 111 and the lower slide rail 112, and the rhomboid frame 21 is located between the upper slide rail 111 and the lower slide rail 112.
[0033] By setting up an upper slide rail 111 and a lower slide rail 112, and respectively installing a first pulley 231 and a second pulley 232 on the support rod 23, the first pulley 231 and the second pulley 232 can slide in the upper slide rail 111 and the lower slide rail 112, thereby achieving bidirectional guidance and restriction of the diamond-shaped telescopic frame 2. The diamond frame 21 is arranged between the upper and lower slide rails 112, which can maintain stable operation during the unfolding and retraction process, avoiding swaying, deviation or jamming caused by single-rail guidance. The structure of the upper slide rail 111 and the lower slide rail 112 not only improves the overall stability of the diamond-shaped telescopic frame 2, but also makes the force on the tarpaulin 3 more even when unfolded, further reducing the risk of central depression and water accumulation, while enhancing the wind resistance and service life of the awning.
[0034] like Figure 1 , Figure 4 and Figure 6 As shown, in an optional embodiment of the utility model, two rhomboid telescopic frames 2 are arranged symmetrically to each other, and a transverse connecting rod 24 is provided between the top ends of two symmetrical support rods 23 in the two rhomboid telescopic frames 2. The transverse connecting rod 24 is connected to the bottom surface of the tarpaulin 3.
[0035] By symmetrically arranging two rhomboid telescopic frames 2 and adding a transverse connecting rod 24 between the tops of the symmetrical support rods 23, the transverse connecting rod 24 is connected to the bottom surface of the tarpaulin 3. This not only forms a transverse support between the two telescopic frames, improving the overall structural stability, but also effectively disperses and balances the force on the tarpaulin 3 in the transverse direction. The transverse connecting rod 24 structure avoids twisting or bulging of the tarpaulin 3 due to uneven force during unfolding, making the surface of the awning smoother and enhancing drainage. At the same time, the transverse connecting rod 24 provides additional support for the tarpaulin 3, improving its load-bearing capacity and wind resistance, thereby further extending the service life of the awning and improving the user experience.
[0036] like Figure 4 and Figure 6 As shown, in an optional embodiment of the utility model, the top ends of the two symmetrical support rods 23 in the two rhomboid telescopic frames 2 are integrally formed with the transverse connecting rod 24.
[0037] By integrally molding the transverse connecting rod 24 between the top ends of the two symmetrical support rods 23 with the support rods 23, the potential problems of loosening and weld point detachment that may occur with traditional screwing or welding methods are avoided, significantly improving the overall structural strength and stability. The integral molding design reduces the number of connection points, lowers assembly steps and maintenance costs, and eliminates swaying and misalignment caused by connection gaps, resulting in more even stress distribution on the bottom surface of the tarpaulin 3. This integral molding design not only improves the reliability of the awning during expansion and contraction but also enhances its overall wind resistance and durability, thereby further extending the awning's service life.
[0038] like Figure 1 and Figure 3 As shown, in an optional embodiment of the utility model, the upper side of the rhombus frame 21 is connected to the lower side of another adjacent rhombus frame 21, and the lower side of the rhombus frame 21 is connected to the lower side of another adjacent rhombus frame 21.
[0039] By connecting the upper side of one rhombus frame 21 to the lower side of an adjacent rhombus frame 21, and then connecting the lower side of another rhombus frame 21 to the lower side of yet another adjacent rhombus frame 21, a tighter and more stable connection is formed between the multiple rhombus frames 21. This structure can effectively distribute the force during the expansion and contraction of the canopy, avoiding deformation or swaying caused by excessive force at a single point, thereby improving the overall stability and balance of the rhombus telescopic frame 2. At the same time, the connection method between the rhombus frames 21 gives it a stronger synergistic extension effect in both the longitudinal and lateral directions, ensuring a flat surface when the tarpaulin 3 is unfolded, reducing sagging in the middle or local bulging, and further improving the drainage performance and wind resistance of the canopy.
[0040] like Figure 6 As shown, in an optional embodiment of the utility model, the support rod 23 is provided with a horizontally oriented through hole 201, and the upper or lower side of the rhomboid frame 21 is rotatably disposed on the through hole 201.
[0041] By providing a horizontally oriented through hole 201 on the support rod 23, and rotatably installing the upper or lower side of the rhombus frame 21 into the through hole 201, a flexible rotatable connection is formed between the rhombus frame 21 and the support rod 23. This structural design provides smoother rotation guidance for the rhombus frame 21 during the unfolding and retraction of the canopy, reducing jamming and wear problems caused by limited hinge positions, thereby improving the smoothness and stability of the telescopic frame operation. At the same time, the rotatable design enhances the overall fit between the rhombus frame 21 and the support rod 23, making the force on the tarpaulin 3 more even when unfolded, further reducing the risk of sagging in the middle of the canopy and localized water accumulation, and improving the durability and service life of the canopy.
[0042] In an optional embodiment of the utility model, the bottom end of the rhomboid frame 21 is provided with a third pulley or slider, which is slidably mounted on the slide rail 11.
[0043] By installing a third pulley or slider at the bottom of the rhombus frame 21, allowing it to slide on the slide rail 11, the rhombus frame 21 receives additional guiding support during expansion and contraction. This structural design effectively distributes the force on the rhombus telescopic frame 2 during movement, reducing deformation or jamming caused by excessive force on a single support point, thereby improving the overall stability and smoothness of the canopy. Simultaneously, the third pulley or slider reduces friction, lowers the operating resistance of the telescopic frame, and extends the service life of the slide rail 11 and supporting components. This structural design further ensures the uniformity of the tarpaulin 3's expansion, preventing sagging and water accumulation in the middle, and enhancing the safety and durability of the canopy.
[0044] like Figure 1 and Figure 2 As shown, in an optional embodiment of the utility model, the retractable awning of this application further includes a base 6, an equipment compartment 7, and a roller shutter door 8. The awning frame 1 is disposed on the base 6, and the equipment compartment 7 and the roller shutter door 8 are respectively disposed on the top two ends of the base 6. The equipment compartment 7 and the roller shutter door 8 are located below the tarpaulin 3.
[0045] By installing a base 6 at the bottom of the canopy, with equipment compartments 7 and roller shutters 8 at both ends of the base 6, and the canopy frame 1 positioned above the base 6, foldable photovoltaic panels can be placed on top of the base 6. This arrangement places the equipment compartments 7 and roller shutters 8 below the tarpaulin 3, achieving an organic integration of the canopy's structure and functional modules. On one hand, the base 6 provides a stable supporting foundation for the canopy, improving the overall structural stability and safety. On the other hand, the arrangement of the equipment compartments 7 and roller shutters 8 facilitates the protection and management of the canopy's retraction and deployment devices and other electrical or mechanical equipment, preventing direct rainwater erosion and extending the equipment's lifespan. Simultaneously, this arrangement facilitates operation and maintenance, making the canopy system more complete and practical, and ensuring the covering effect and reliability of the tarpaulin 3 when unfolded.
[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
