[0024] To better understand the purpose, structure, and function of this utility model, a retractable sunshade device of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 6 As shown, this utility model discloses a retractable sunshade device, including a curtain wall 37 mounted on a wall 36, with the curtain wall 37 connected to the wall 36 via a keel (this is prior art). Two mounting feet 1 are arranged parallel to each other on the wall 36, with a portion of each mounting foot 1 penetrating the curtain wall 37 and extending outwards. A sunshade device for shading a scenic balcony is also provided on the two mounting feet 1, with the sunshade device located on the portion of the mounting feet 1 outside the curtain wall 37 for easy assembly and disassembly. Specifically, the curtain wall 37 includes an upper curtain wall 37, a lower curtain wall 37, and a recessed curtain wall 38 located between the upper and lower curtain walls 37. The mounting feet 1 penetrate the recessed curtain wall 38, and the sunshade device is housed within the recessed curtain wall 38.

[0026] A frame and supporting folding devices are provided on the frame and the recessed curtain wall 38 between the two mounting feet 1. Sunshade components are mounted on the frame and the supporting folding devices. By placing the mounting feet 1, the frame, and the retracted sunshade devices within the recessed curtain wall 38, the sunshade components can be hidden within the recessed curtain wall 38 when fully retracted. This maintains a smooth, clean, and modern appearance on the building facade, eliminates the abruptness of traditional awnings, achieves a fusion of functionality and architectural aesthetics, enhances the overall beauty of the building, and makes the building's appearance more concise and streamlined.

[0027] The shading component specifically includes a tubular motor 34 mounted on a frame and connected to an external power source. A roller 33, on which a shading cloth 32 is wound, is mounted on the tubular motor 34, and the free end of the shading cloth 32 is connected to a support and folding device. The support and folding device can extend on its own without external restraint. That is, when the tubular motor 34 drives the roller 33 to rotate and release the shading cloth 32, the support and folding device will pull the shading cloth 32 as the tubular motor 34 is released, causing it to slowly unfold and expand its shading area. The unfolded shading cloth 32 will then achieve the shading effect for the landscape balcony.

[0028] The supporting folding device for supporting the sunshade fabric 32 includes two adjustment mechanisms mounted on the frame. Each adjustment mechanism is equipped with a support frame, and the free ends of the two support frames are connected via end sleeves 27. The free end of the sunshade fabric 32 is connected to the end sleeves 27. Figure 4 and Figure 5 As shown, the support frame includes a connecting block 13 mounted on an adjusting mechanism. A first curved arm 17 is rotatably mounted on the connecting block 13, and a second curved arm 19 is rotatably mounted on the free end of the first curved arm 17 via a connector. A torsion spring 22 is mounted on the connector to cooperate with the first curved arm 17 and the second curved arm 19. An end sleeve 27 is located between the two second curved arms 19. Specifically, a bearing frame 15 is rotatably mounted on the connecting block 13 via a fifth bolt assembly 16. The bearing frame 15 is C-shaped, and the first curved arm 17 is fixedly mounted on the side of the bearing frame 15 opposite to its opening, so that the first curved arm 17 on the support frame rotates with the connecting block 13 when the support frame is in operation.

[0029] The first curved arm 17 and the second curved arm 19 of the aforementioned supporting folding device provide stable support for the unfolding of the sunshade 32, ensuring its flatness and stability during extension and retraction, and effectively resisting crosswinds. The torsion spring 22 applies external force to the first curved arm 17 and the second curved arm 19 when the tubular motor 34 drives the drum 33 to release the sunshade 32, causing the first curved arm 17 and the second curved arm 19 to unfold, simultaneously supporting and unfolding the sunshade 32. When it is necessary to rewind the unfolded sunshade 32, the tubular motor 34 is controlled to rotate in the opposite direction. At this time, the tubular motor 34 drives the drum 33 to rewind the sunshade 32, and the sunshade 32 will generate an inward pulling force on the end sleeve 27. Under the action of the inward pulling force of the end sleeve 27, the second curved arm 19 and the first curved arm 17 of the two support frames begin to rotate around the connection point, overcoming the force of the torsion spring 22 and compressing it, causing the support frame to gradually fold and retract. The entire supporting folding device retracts towards the curtain wall 37 along with the sunshade 32. When the sunshade fabric 32 is completely wrapped around the roller 33, the supporting folding device is also completely folded and retracted into the space formed by the recessed curtain wall 38. It should be noted that when the first curved arm 17 and the second curved arm 19 on the supporting folding device are folded, their connection points will move closer together to reduce the space occupied by the outward folding of the first curved arm 17 and the second curved arm 19. The tubular motor 34 used to drive the rotation of the roller 33 can be controlled by an external remote control or an external switch; no further restrictions are placed here.

[0030] like Figure 2 and Figure 3 As shown, the frame includes a load-bearing pipe 2 positioned between two mounting feet 1 and a steel frame 4 mounted on the load-bearing pipe 2. An adjustment mechanism is detachably mounted on the load-bearing pipe 2 on the outside of the mounting feet 1. Specifically, the steel frame 4 includes a steel block 41 and an L-shaped frame 42 on the bottom surface of the steel block 41. The opening formed by the combination of the L-shaped frame 42 and the steel block 41 allows the load-bearing pipe 2 to be inserted. An installation opening is located on the steel block 41. A second bolt assembly 43 is vertically positioned near the opening of the steel block 41 and the L-shaped frame 42, allowing for tightening of the opening and limiting and clamping of the load-bearing pipe 2 within the opening. The combination of the steel block 41 and the L-shaped frame 42 forms a strong clamping structure. Tightened by the second bolt assembly 43, it can be securely locked onto the load-bearing pipe 2, thereby improving the stability of the steel frame 4 on the load-bearing pipe 2 and the ease of assembly and disassembly. A tubular motor 34 is detachably mounted between the two steel blocks 41. Furthermore, a fixing hole 411 for passing through the positioning bolt is opened on the steel block 41, and a screw hole for connecting with the positioning bolt is opened on the tubular motor 34. The positioning bolt passes through the fixing hole 411 and is then connected to the tubular motor 34 with a bolt.

[0031] like Figure 2As shown, the mounting foot 1 includes an L-plate 101 mounted on the wall 36 via expansion bolts. A pressure plate 102 is located within the L-plate 101, and the length of the pressure plate 102 is adapted to the bottom plate of the L-plate 101. The load-bearing tube 2 is located between the bottom plate of the L-plate 101 and the pressure plate 102. A first bolt assembly 3 is provided at the free end of the bottom plate of the L-plate 101 and the pressure plate 102 to clamp the load-bearing tube 2. The load-bearing tube 2 is placed between the bottom plate of the L-plate 101 and the pressure plate 102. Then, the second bolt assembly 43 is installed and initially tightened, so that the pressure plate 102 and the bottom plate of the L-plate 101 initially clamp the load-bearing tube 2. However, the load-bearing tube 2 can still move between the bottom plate of the L-plate 101 and the pressure plate 102. After adjusting the load-bearing tube 2 to ensure that it is in the optimal installation position, the second bolt assembly 43 is tightened.

[0032] like Figure 3 and Figure 4 As shown, the adjustment mechanism includes an adjustment frame 5, with a connecting mechanism located on the side of the adjustment frame 5 opposite to the load-bearing pipe 2. A guide hole 10 is opened in the upper middle part of the adjustment frame 5, and a connecting hole 11 is opened in the lower middle part of the adjustment frame 5. A fourth bolt assembly 14 is provided on the connecting block 13 at both the guide hole 10 and the connecting hole 11. The fourth bolt assembly 14 located in the connecting hole 11 is rotatably connected to it, while the fourth bolt assembly 14 located in the guide hole 10 can move along the contour of the guide hole 10. Simultaneously, an adjusting bolt 18 extending towards the interior of the guide hole 10 is threaded onto the external part of the adjustment frame 5, and the adjusting bolt 18 supports the fourth bolt assembly 14 within the guide hole 10. By rotating the adjusting bolt 18, the horizontal angle of the support frame can be precisely controlled. Furthermore, the guide hole 10 provides a clear movement trajectory for the fourth bolt assembly 14 in the upper middle part of the adjustment frame 5. This allows the angle of the support frame to be steplessly adjusted within this range to change the shading range of the sunshade cloth 32 for the interior and the landscape balcony. During adjustment, the adjusting bolt 18 is screwed in clockwise. The end of the adjusting bolt 18 is pushed inward, pushing the fourth bolt assembly 14 located in the guide hole 10. The fourth bolt assembly 14 drives the connecting block 13 to rotate counterclockwise around the lower part of the fourth bolt assembly 14. At this time, the connecting block 13 also drives the support frame to rotate counterclockwise, thereby changing the horizontal angle of the support frame. It can also change the horizontal angle of the sunshade cloth 32 between the end sleeve 27 and the roller 33. At the same time, when it is necessary to adjust the angle of the support frame in the opposite direction, the adjusting bolt 18 can be rotated in the opposite direction.

[0033] like Figure 4As shown, the connecting mechanism for connecting the adjusting frame 5 and the load-bearing pipe 2 includes an upper support arm 7 and a lower support arm 6 located at one end of the adjusting frame 5. A gap is left between the upper support arm 7 and the lower support arm 6 for the load-bearing pipe 2 to be inserted. Limiting blocks 8 are provided on the bottom surface of the free end of the upper support arm 7 and the top surface of the free end of the lower support arm 6. The two limiting blocks 8 limit and position the load-bearing pipe 2 located between the upper support arm 7 and the lower support arm 6, facilitating the installation of the load-bearing pipe 2. A third bolt assembly 9, which allows for adjustment of the gap opening, is vertically provided on the upper support arm 7 and the lower support arm 6. The upper support arm 7, the lower support arm 6, and the adjusting clamp are combined to form a C-shaped opening. When installing it, the load-bearing tube 2 can be inserted into the upper support arm 7, the lower support arm 6, and the limiting block 8 of each support arm. Then, the third bolt assembly 9 is used to vertically pass through the upper support arm 7 and the lower support arm 6 and is tightened. When the bolt is tightened, a strong axial tensile force is generated. This tensile force attempts to bring the upper support arm 7 and the lower support arm 6 closer to each other and clamp the load-bearing tube 2.

[0034] like Figure 5 As shown, the connecting component between the first curved arm 17 and the second curved arm 19 specifically includes a first connecting frame 12 located at the free end of the first curved arm 17 and a second connecting frame 20 located on the second curved arm 19. Both the first connecting frame 12 and the second connecting frame 20 are C-shaped, with the second connecting frame 20 located inside the first connecting frame 12. The first connecting frame 12 and the second connecting frame 20 are rotatably connected by a sixth bolt assembly 21, and a torsion spring 22, which cooperates with the first curved arm 17 and the second curved arm 19, is sleeved on the sixth bolt assembly 21 between the first connecting frame 12 and the second connecting frame 20. In use, when the tubular motor 34 retracts the sunshade cloth 32, a pulling force is applied to the second curved arm 19 through the end sleeve 27, forcing the entire support frame to fold. During this folding process, the second curved arm 19 rotates relative to the first connecting frame 12 around the axis of the sixth bolt assembly 21 via the second connecting frame 20. This causes the two lever arms of the torsion spring 22, which is fitted onto the sixth bolt assembly 21, to be compressed, resulting in torsional deformation of the torsion spring 22 and the conversion of mechanical energy into stored elastic potential energy. When the tubular motor 34 releases the sunshade 32, the end sleeve 27 reduces the constraint on the torsion spring 22 via the second curved arm 19. The torsion spring 22, now twisted, begins to release its stored elastic potential energy. The energy released by the torsion spring 22 acts on the first connecting frame 12 and the second connecting frame 20 through its lever arms, ultimately reaching the torque required to drive the first curved arm 17 and the second curved arm 19 to unfold. The first curved arm 17 and the second curved arm 19 extend to a predetermined angle, forming a rigid triangular support structure and smoothly unfolding the sunshade 32.

[0035] A frame 23 is rotatably mounted on one end of the second curved arm 19 relative to the second connecting frame 20 via a seventh bolt assembly 25, and a bracket 24 is mounted on one side of the frame 23. Both the frame 23 and the bracket 24 are C-shaped. An end sleeve 27 is mounted on the bracket 24, and the bracket 24 and the end sleeve 27 are detachably connected. The arrangement of the frame 23 and the bracket 24 forms a pull-up frame structure with the end sleeve 27 combined with the frame 23 and the bracket 24. When the support frame is unfolded and folded, the second curved arm 19 on the support frame and the frame 23 on the pull-up frame rotate around the seventh bolt assembly 25 as the midpoint, and the pull-up frame structure does not deform, thus providing stable support for the sunshade cloth 32.

[0036] like Figure 6 As shown, the end sleeve 27 is arc-shaped, and both its upper and lower ends are provided with open tubes 30 with openings in their peripheral walls. The sunshade cloth 32 is placed inside the open tubes 30 via an insertion rod 31. The insertion rod 31 can drive the sunshade cloth 32 into the open tube 30, thereby fixing the sunshade cloth 32 inside the open tube 30. This design makes the installation and removal of the sunshade cloth 32 extremely simple, and can be completed without complicated tools. When the sunshade cloth 32 needs to be cleaned or replaced due to long-term use, it can be quickly removed from the end sleeve 27, greatly reducing the later maintenance costs and time. Furthermore, an I-beam frame 28 is provided inside the end sleeve 27, and the inner sides of the two horizontal plates of the I-beam frame 28 near the bracket 24 are provided with protrusions 29, with an installation gap between the two protrusions 29. Meanwhile, an extension arm 35 is provided inside the end sleeve 27 below the I-beam frame 28. The bottom surface of the extension arm 35 near the bracket 24 has a protrusion 29. A protrusion 29 that mates with the protrusion 29 of the extension arm 35 is also provided on the open cylinder 30 at the bottom of the end sleeve 27. An installation gap is also provided between the protrusion 29 of the extension arm 35 and the protrusion 29 of the open cylinder 30. The extension arm 35, the protrusion 29 of the extension arm 35, the open cylinder 30 at the bottom of the end sleeve 27, and the protrusion 29 on the bottom open cylinder 30 form a traction mechanism. Fixing bolts 26 are detachably installed in each installation gap. The screw of the fixing bolt 26 can slide within the installation gap, and the gap of the installation gap is smaller than the size of the nut of the fixing bolt 26, so that the installation gap limits the movement of the fixing bolt 26. Holes corresponding to the positions of each fixing bolt 26 are also provided on the bracket 24 for the fixing bolt 26 to pass through. Meanwhile, a fixing nut is provided on the fixing bolt 26 to cooperate with it, and the fixing nut is located inside the bracket 24. By tightening the fixing nut, the end sleeve 27 can be fixed to the bracket 24 through the I-beam frame 28 and the traction mechanism.

[0037] Instructions for use: When sun shading is needed, start the tubular motor 34. The tubular motor 34 drives the roller 33 to release the sunshade cloth 32. At this time, the elastic potential energy stored in the torsion spring 22 in the connecting piece between the first curved arm 17 and the second curved arm 19 in the support folding device begins to be released, supporting the unfolding of the first curved arm 17 and the second curved arm 19. The second curved arm 19 pulls the sunshade cloth 32 outward through the end sleeve 27. The first curved arm 17 and the second curved arm 19 form a rigid support frame to stably support the sunshade cloth 32. After being fully unfolded, the sunshade cloth 32, with the stable support frame and the secure end sleeve 27 connection, effectively shades the balcony or window.

[0038] When the sunshade device needs to be retracted, the control tubular motor 34 rotates in the reverse direction to retract the sunshade fabric 32. The sunshade fabric 32 generates a pulling force on the end sleeve 27 towards the drum 33. This pulling force forces the second curved arm 19 and the first curved arm 17 of the support frame to overcome the force of the torsion spring 22 and gradually rotate and fold around the connection points. The entire support folding device retracts towards the curtain wall 37 along with the end sleeve 27. Finally, the sunshade fabric 32 is completely wrapped around the drum 33, the support frame is also completely folded, and together with the end sleeve 27, the frame, and other components, it is stored in the space formed by the recessed curtain wall 38 of the building, restoring the clean and smooth appearance of the building facade.
