[0002] Compared with aluminum alloy sunshade roller shutter, the curtain fabric sunshade product has simpler structure, higher safety performance and wider application range. The curtain fabric sunshade product includes a roller sunshade curtain, a folding arm type external sunshade curtain and a vertical arm type external sunshade curtain. Among them, the roller sunshade curtain is mostly installed indoors and has weak performance of blocking radiation from entering the building interior. At the same time, the pressure difference between the inside and outside of the window will cause the curtain fabric to be adsorbed on the window, hindering the indoor ventilation. Therefore, in order to make the fabric roller shutter have better sunshade effect when applied to the building external sunshade, a guide device needs to be provided for the fabric roller shutter.

[0003] Although the patent document CN111140157A discloses a door and window with fabric sunshade, in which an installation groove is formed on the upper side of the wall body corresponding to the door and window opening, the sunshade curtain box is fixedly arranged in the installation groove, and the sunshade curtain box is flush with the outer side of the wall body. The device installs the fabric roller shutter type sunshade curtain on the outer wall of the building, and makes the flatness of the building external facade better. However, the device lacks the design of the wind resistance performance of the roller shutter, and it is difficult to meet the demand of the external sunshade of high-rise buildings.

[0004] The ventilation performance of the folding arm type external sunshade roller shutter is better than that of the roller sunshade curtain, but when it is used, the folding arm needs to be stretched to the outside of the wall, which affects the appearance of the overall outer wall surface of the building. The sunshade angle of the vertical arm type external sunshade curtain is difficult to control, and the wind resistance performance is poor, which is also difficult to be applied to the external sunshade of high-rise buildings.

[0005] The patent document CN1978861B discloses a roller shutter device, which has a roller shutter box for storing the roller shutter, a guide rail for receiving the two end portions of the roller shutter, a first frame extending along the length direction of the guide rail, and a second frame extending along the length direction of the roller shutter box. The device is installed by detachably fixing the first frame of the mounting component on the guide rail and detachably fixing the second frame on the mounting surface of the roller shutter box. The guide rail of the roller shutter device is exposed on the visible appearance surface of the guide rail during installation, which affects the overall appearance on the one hand, and the fasteners are exposed on the outside for a long time, which accelerates the aging degree and increases the difficulty of maintenance and disassembly.

[0006] In summary, in the field of building sunshade technology, how to design a guide rail structure to provide guidance for the fabric roller shutter during the storage and release process, and make the mounting fasteners hidden in the interior of the guide rail, has become a technical problem to be solved by the technical personnel in the field.

[0039] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0040] like Figure 1 The illustrated external sunshade fabric roller blind with guide rails enhances the guiding effect of the fabric roller blind, reduces the impact of air pressure differences on the sunshade surface, and effectively maintains the flatness of the sunshade surface. The guide rail, formed by a guide rail fixing seat and an outer cover, creates a guide groove. A snap-fit ​​groove engages within the guide groove, and a sliding groove is inserted into the snap-fit ​​groove. The side of the fabric roller blind is inserted into the track of the sliding groove. On one hand, the guide rail guides the movement direction of the fabric roller blind; on the other hand, the track provides horizontal positioning for the side of the fabric roller blind, reducing the impact of air pressure differences on the sunshade surface and improving the flatness of the fabric roller blind.

[0041] like Figure 1 As shown, the external sunshade roller blind with guide rail includes a housing 1, guide rail, fabric roller blind 6, bottom beam 4, and drive assembly 7 housed within the housing 1. The housing 1 is fixedly mounted on the wall. A roller blind groove for the fabric roller blind 6 to pass through is provided at the rear end of the housing 1. One end of the fabric roller blind 6 is connected to the drive assembly 7, and the other end extends from the roller blind groove, causing the fabric roller blind 6 to hang down under gravity.

[0042] The housing 1 includes an upper housing 11 and a lower housing 12. The upper housing 11 is fixedly connected to the wall with the reserved window opening. A left end seat 13 and a right end seat 14 are fixedly installed on both sides of the upper housing 11. The lower housing 12 is fixedly connected to the left end seat 13 and the right end seat 14 on both sides, forming a cavity with a roller shutter groove together with the upper housing 11. The drive assembly 7 is installed inside the cavity. With this configuration, the lower housing 12 can serve as an access port for the housing 1, facilitating the opening of the housing 1 and maintenance of the drive assembly 7 inside. The lower housing 12 may have an L-shaped cross-section. Preferably, the lower housing 12 may be made of bent sheet metal.

[0043] The drive assembly 7 includes a drive shaft 75 and a motor 71 that provides power for the rotation and winding of the fabric roller blind 6. The motor 71 is fixedly mounted on the left end seat 13 of the housing 1. The output shaft of the motor 71 is connected to the driving end of the drive shaft 75. The driven end of the drive shaft 75 is connected to the right end seat 14 via a bearing. The appropriate model of the motor 71 can be selected according to the size of the fabric roller blind 6, thereby determining the motor power. The motor 71 can be an AC motor or a DC motor.

[0044] The four sides of the fabric roller blind 6—the beginning, end, left, and right sides—are connected to the drive shaft 75, the bottom beam 4, the left guide rail 2, and the right guide rail 3, respectively. The beginning of the fabric roller blind 6 is clamped by the upper buckle 76, and the fabric roller blind 6 rolls along the outer contour of the upper buckle 76 and is inserted into the upper buckle groove of the drive shaft 75. The end of the fabric roller blind 6 is clamped by the lower buckle, and the fabric roller blind 6 rolls along the outer contour of the lower buckle and is engaged in the lower buckle groove of the bottom beam 4. It should be noted that the installation of the bottom beam 4 and the end of the fabric roller blind 6 must be carried out during the on-site installation of the electric fabric roller blind.

[0045] like Figure 1 Combination Figure 3 As shown, the guide rails include a left guide rail 2 and a right guide rail 3, both of which are fixedly mounted to the wall on their sides. Guide grooves are provided on the opposite surfaces of the left and right guide rails 2 and 3. A snap-fit ​​groove 22 engages within the guide groove. A sliding groove 23 is inserted into the snap-fit ​​groove 22. The sliding groove 23 has a track and a tensioning end face. The roller blind side protrusion 61 is inserted into the track, and an elastic component providing horizontal tension to the fabric roller blind 6 is provided between the tensioning end face and the snap-fit ​​groove 22. It is worth noting that the insertion process of the roller blind side protrusion 61 into the track is also performed during the on-site installation of the electric fabric roller blind.

[0046] like Figure 2 Combination Figure 3 As shown, a guide rail for a fabric roller blind includes a guide rail fixing seat 21, an outer cover 25, a fastening groove 22, and a sliding groove 23. A guide rail bottom cover 26 is inserted into the tail end of the guide rail fixing seat 21. The outer cover 25 is fixedly mounted on the guide rail fixing seat 21. The guide rail fixing seat 21 and the outer cover 25 together form a guide groove. The guide groove has a cavity inside, and a pair of positioning steps are provided at the opening of the cavity. The openings of the guide groove cavities of the left guide rail 2 and the right guide rail 3 are positioned opposite each other.

[0047] The guide rail bottom cover 26 is fixedly mounted on the first mounting platform inside the guide rail mounting base 21 by the first fastening screw 27. The outer cover 25 is fixedly mounted on the second mounting platform inside the guide rail mounting base 21 by the second fastening screw 28, and the second mounting platform is located at the bottom of the guide groove. With this configuration, mounting screws are avoided from appearing on the visible surface of the guide rail, as they are all hidden inside the guide rail, further improving the product's aesthetics.

[0048] The first fastening screw 27 can be a cross-head self-tapping screw conforming to GB / T 845, which reduces the need for drilling and tapping on the inner mounting plate of the guide rail fixing seat 21, thus improving production efficiency. The first fastening screw 27 can preferably be a cross-head self-tapping screw with a cut-off end, facilitating chip removal during tapping and further improving installation efficiency.

[0049] The second fastening screw 28 can also be a cross-head self-tapping screw conforming to GB / T 845, which reduces the drilling and tapping process on the inner side of the second mounting platform of the guide rail fixing seat 21, improving production efficiency. The second fastening screw 28 can preferably be a cross-head self-tapping screw with a cut-off end, facilitating chip removal during tapping and further improving installation efficiency. The first fastening screw 27 and the second fastening screw 28 can be selected according to the actual dimensions of the guide rail. Using the same specification for the first fastening screw 27 and the second fastening screw 28 helps reduce the types of fasteners used, further improving installation efficiency.

[0050] The fastener 22 engages within the cavity of the guide groove. The bottom of the fastener 22's mounting handle has a slot, into which a positioning step is placed, positioning the fastener 22 within the guide groove. The sliding groove 23 is inserted into the fastener 22. The sliding groove 23 has a tensioning end face and a track for the side of the fabric roller blind to be inserted. An elastic component is provided between the tensioning end face and the fastener groove.

[0051] like Figure 3 and Figure 4 As shown, the side of the guide rail fixing seat 21 is fixedly mounted to the mounting surface by a third fastening screw 29. The third fastening screw 29 passes through the side of the guide rail fixing seat 21 from the inside. The gap between the side of the guide rail fixing seat 21 and the mounting surface is filled with sealant to form a sealing layer. This arrangement further improves the anti-seepage performance of the guide rail side. The third fastening screw 29 can be a cement nail.

[0052] The guide groove has a C-shaped cross-section, which facilitates the selection of suitable profiles for the guide rail fixing seat 21 and the outer cover 25 for assembly, and makes the processing and installation of the guide groove easier. A slot is provided on the first end face of the guide rail fixing seat 21, which facilitates the connection between the end seat pin provided at the lower end of the cover 1 of the fabric roller blind and the guide rail.

[0053] The guide rail fixing base 21 has an L-shaped transverse section, which allows it to be self-supported on the windowsill surface during installation, further reducing the difficulty of installing the guide rail. Preferably, a slot is provided on the first end face of the guide rail fixing base, which facilitates the connection between the end bracket pin at the lower end of the fabric roller blind cover and the guide rail.

[0054] A sealing structure is provided at the connection between the guide rail fixing seat 21 and the outer cover 25. The sealing structure includes a first sealing groove on the guide rail fixing seat 21 and a second sealing groove on the outer cover 25. The first sealing groove and the second sealing groove form a snap-fit, further improving the sealing performance inside the guide rail.

[0055] like Figure 3 As shown, the guide rail can be installed within pre-reserved window openings in the building construction. The mounting surface is selected as the side wall inside the window opening. One side of the L-shaped guide rail fixing seat is fixed to the side wall using a third fastening screw. This helps maintain the original design of the building facade and avoids disrupting the overall design style. For example, when adding a sunshade fabric roller blind with a guide rail to a retro-style building, the guide rail can be installed inside the building's window opening, avoiding a clash between the technological sunshade product and the building's style.

[0056] like Figure 4 As shown, the guide rail can also be installed on the exterior facade of the building. The mounting surface can be the outer wall of the building or the outer surface of the window frame. The other side of the L-shaped guide rail fixing seat is fixed to the outer wall or the outer surface of the window frame by a third fastening screw. For example, if the building has high requirements for reducing its energy consumption, installing the fabric roller blind with guide rail on the wall helps to reduce heat radiation entering the building from the window.

[0057] like Figure 3 As shown, the retaining groove 22 engages within the cavity of the guide groove. The retaining groove 22 has a bottom wall and two side walls. A positioning part, a wedge part, a retaining groove, and an installation handle are sequentially formed along the bottom wall on the side walls. The positioning part positions the retaining groove 22 within the cavity of the guide groove in a direction perpendicular to the center line of the retaining groove. The positioning part fits tightly against the inner wall of the guide groove, which helps increase the friction between the retaining groove and the guide groove, preventing the retaining groove from sliding along the extension direction of the guide rail, and further improving the stability of the guide rail.

[0058] The slot is used to engage with the positioning step in the guide groove. When the installation handle is gripped by the installation tool, it causes the wedge and slot to retract, inserting or removing the retaining slot into the guide groove along the groove opening. The installation tool can be a caliper. The cooperation between the slot and the positioning step prevents the retaining slot from coming out of the guide groove opening under extreme weather conditions, further improving the guide rail's resistance to damage.

[0059] The inner side of the mounting handle is connected to a bent portion. The bent portion bends inward into the groove 22. The end of the bent portion is used to position the slide 23 inside the groove 22 in the direction of the groove centerline. The end of the bent portion can further limit the displacement of the slide in the direction of the groove centerline.

[0060] The slide rail includes a base and a track. The base has a tensioning end face. The track is fixed to the center of the tensioning end face. The side of the base is used to position the slide rail within the groove, perpendicular to the centerline of the groove. The bottom surface of the base contacts the bottom wall of the groove, forming a first extreme position where the slide rail is within the groove along its centerline. The tensioning end face of the base contacts the end of the bend, forming a second extreme position where the slide rail is within the groove along its centerline. These first and second extreme positions help protect the fabric roller blind and effectively alleviate internal tension.

[0061] The sides of the slide base are used to position the slide inside the groove, perpendicular to the center line of the groove. This design allows the inner wall of the groove to restrict the slide's range of motion when the slide is not fitted with elastic components or connected to the side of the fabric roller blind, preventing the slide from flipping inside the groove and thus affecting the efficiency of on-site installation.

[0062] The elastic component can be a steel wire spring 24, which has a simple structure, is easy to maintain and repair, and is also easy for workers to install. Multiple sets of steel wire springs 24 are evenly distributed along the extension direction of the guide rail, which is beneficial for applying uniform tension to the fabric roller blind 6. At the same time, the setting of steel wire springs 24 allows the fabric roller blind inserted into the track to form a flexible connection with the guide rail, which can effectively reduce the side wear of the fabric roller blind, extend the maintenance cycle of the fabric roller blind, and improve its service life.

[0063] The clamping surface of the mounting handle is provided with wavy protrusions, which facilitates the clamping of the mounting slot by the fixture, further increasing the friction between the mounting handle and the fixture, preventing the slot from falling off the fixture, reducing the difficulty of installation, and improving the efficiency of on-site construction of the guide rail.

[0064] A sealing strip 5 is inserted into the tail end of the bottom beam 4. A counterweight is added inside the cavity of the bottom beam 4, which helps to increase the tension of the fabric roller blind 6 in both the vertical and horizontal directions. This further improves the flatness of the fabric roller blind 6 during opening and closing, and also enhances its windproof effect. The counterweight can be a metal block, preferably an iron block. The sealing strip 5 can be a rubber sealing strip.

[0065] This embodiment also provides a method for installing a guide rail for a fabric roller blind, including the following steps:

[0066] Step 1: Determine the installation position of the guide rail based on the position of the fabric roller blind cover;

[0067] Step 2: Use the third fastening screw to pass through the inside of the guide rail mounting base and fix the side of the guide rail mounting base to the mounting surface;

[0068] Step 3: Assemble the outer cover and the guide rail fixing base, and enclose them to form a guide groove. Use the second fastening screw to fix the outer cover on the second mounting platform inside the guide rail fixing base on the inside of the guide groove.

[0069] Step 4: Use the first fastening screw to fix the bottom of the guide rail to the first mounting platform inside the guide rail fixing seat on the inside of the guide groove.

[0070] Step 5: Use the installation tool to clamp the clamping surface of the mounting handle of the buckle groove and apply pressure to the clamping surface to cause the bottom of the buckle groove to contract, thus locking the buckle groove into the guide groove. The positioning step of the guide groove is locked into the slot at the bottom of the mounting handle.

[0071] In step one, the position of the fabric roller blind's casing is usually determined based on the dimensions of the pre-reserved window opening, specifying the model of the motorized fabric roller blind for external sun shading. The drive assembly is pre-installed into the casing, and the upper fastening strip at the beginning of the fabric roller blind is inserted into the upper fastening strip groove of the drive shaft. Finally, after leveling and marking within the window opening, the casing is positioned and installed. The casing can be installed directly on the exterior wall of the building or inside the window opening.

[0072] The guide rails are installed directly below the roller blind groove of the casing. The mounting surface is leveled and marked for positioning, ensuring the parallelism between the left and right guide rails, as well as their perpendicularity to the casing, to prevent the fabric roller blind from jamming during rolling. The final installation positions of the left and right guide rails are then determined. Before installation, installers can use a measuring ruler to further verify the accuracy of the marked positioning.

[0073] In step two, the third fastening screw can be selected according to the different types of screws used on the mounting surface. For example, if the mounting surface is a wall, a cement nail is preferred; if the mounting surface is an aluminum alloy window frame, a Phillips head self-tapping screw with a rounded head and a notched tail is preferred, which facilitates chip removal during tapping and improves installation efficiency. When fixing the side of the guide rail mounting bracket to the mounting surface, the installer can choose to install manually or with the help of power tools. During installation, any falling cement dust or metal shavings can be blown away with an air gun to ensure cleanliness during the installation process.

[0074] In step three, the second fastening screw is preferably a Phillips head self-tapping screw with a rounded head and a cut-off end. The second fastening screw secures the outer cover to the second mounting platform inside the guide rail fixing seat on the inner side of the guide groove. Metal shavings generated during installation are also removed using an air gun. To prevent scratches on the surface of the outer cover during installation, a protective film can be applied to the surface of the outer cover before assembling it with the guide rail fixing seat. The protective film can be removed after all installation steps are completed.

[0075] In step five, a sliding groove is pre-inserted into the inside of the retaining groove, and the elastic component is installed between the tensioning end face of the sliding groove and the retaining groove. For example... Figure 5 As shown in the diagram, viewed from the rear end of the guide rail, the outer cover 25 is fixedly mounted on the second mounting platform inside the guide rail fixing seat 21 by the second fastening screw 28. The guide rail bottom cover 26 is fixedly mounted on the first mounting platform inside the guide rail fixing seat 21 by the first fastening screw 27. The slide groove 23 is inserted into the snap groove 22 from the rear end. The wire spring 24 is placed between the tensioning end faces of the snap groove 22 and the slide groove 23. The mounting fixture applies an inward clamping force to the mounting handle of the snap groove 22, causing the snap groove 22 to contract and engage with the guide groove formed by the outer cover 25 and the guide rail fixing seat 21.

[0076] like Figure 6 The diagram shows a partial assembly of the guide rail, viewed from the beginning. The beginning of the fabric roller blind 6 is equipped with an upper fastening strip 76. An upper fastening strip groove is provided on the drive shaft 75. The upper fastening strip 76 is inserted into the upper fastening strip groove. The end of the fabric roller blind 6 is equipped with a lower fastening strip. A lower fastening strip groove is provided on the bottom beam 4. The lower fastening strip is snapped into the lower fastening strip groove. A roller blind side protrusion 61 is provided on the side of the fabric roller blind 6. The beginning of the fabric roller blind is connected to the drive shaft via the upper fastening strip, reducing the complexity of assembling the electric fabric roller blind, making it easier for operators to master, and improving assembly efficiency.

[0077] In step five, the inside of the retaining groove can be pre-inserted with a sliding groove, and the elastic component is installed between the tensioning end face of the sliding groove and the retaining groove. The retaining groove can also be installed in a split manner, that is, the retaining groove is divided into an upper retaining groove and a lower retaining groove. During installation, first use the installation tool to clamp the clamping surface of the installation handle of the upper retaining groove, and apply pressure to the clamping surface to cause the bottom of the upper retaining groove to contract, thus locking the upper retaining groove into the guide groove. The positioning step of the guide groove is locked into the slot at the bottom of the installation handle.

[0078] The upper locking groove is positioned with the tail end face of the housing as the positioning reference. After fixing the upper locking groove in the guide groove, the first end of the slide groove is inserted into the tail end of the upper locking groove, and a steel wire spring is installed between the tensioning end face of the slide groove and the upper locking groove. Then, utilizing the flexibility of the slide groove, the tail end of the slide groove is inserted into the lower locking groove from the first end of the lower locking groove. The first end of the lower locking groove is positioned with the tail end face of the upper locking groove as the positioning reference. The clamping surface of the installation handle of the lower locking groove is clamped using an installation tool, and pressure is applied to the clamping surface, causing the bottom of the lower locking groove to contract and engage with the guide groove. The locking groove adopts a segmented installation, which facilitates the disassembly of the guide rail during maintenance. Maintenance and upkeep of the guide rail can be completed without disassembling the housing.
