Description

Technical Field

[0001] The utility model relates to the technical field of outdoor sunshades, and specifically relates to a scissor-type waterproof folding awning. Background Art

[0002] The folding awning is one of the essential facilities for modern outdoor sunrooms or outdoor windows. It not only adds a unique charm in terms of aesthetics, but more importantly, it meets people's pursuit of comfort in terms of function. Through delicate design, the folding awning curtain not only ensures ventilation and air exchange, but also provides excellent sunshade effect. In the hot summer, it can effectively block the direct sunlight, reduce the rise of indoor temperature, and thus create a more cool and pleasant living environment. Such a design not only improves the practicality of the sunroom, but also enhances people's living experience.

[0003] In a folding aluminum alloy awning with the patent number CN202322600309.1, the longer sides of two-by-two folding louvers are directly hinged together. When retracted, one end drives the folding louvers to contract, that is, both ends of the folding louvers are connected to other folding louvers, which means that all the folding louvers are connected in series. When disassembling and replacing, both sides of the damaged folding louver need to be removed to disassemble the entire folding louver. When installing, both sides of the folding louver need to be installed in place to complete the installation, which is rather inconvenient. Secondly, this way of contracting and unfolding the folding louvers is in the form of a curtain. The folding louvers gradually contract and unfold from one side to the other side, and the sunlight also gradually spreads or fades from one side to the other side, with poor aesthetics. Thirdly, by directly hinging two-by-two folding louvers, when the folding louvers contract, due to the angle limitation of the hinge, the folding louvers cannot be completely contracted together, that is, they are not in a vertically close state, resulting in a reduced degree of sunlight reception. Finally, the way of hinging the folding louvers to each other results in poor waterproof effect between the louver blades. Content of the Utility Model

[0004] (I) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present utility model provides a scissor-type waterproof folding awning, which has the advantages of being able to remove damaged curtain sheets without affecting adjacent curtain sheets, being more convenient for disassembly and installation, making the dimming method more aesthetic, being able to completely retract the curtain sheets so that each curtain sheet is in a vertical state and closely adheres together, increasing the degree of sunlight reception and enhancing the waterproof effect between curtain sheets, and solving the problem that in awnings where all folding louvers are connected in series, when removing and replacing a folding louver, it is necessary to remove both sides of the damaged folding louver and the adjacent folding louvers to remove the entire folding louver, and during installation, both sides of the folding louver need to be installed in place to complete the installation, which is rather inconvenient. Secondly, this method of contracting and expanding the folding louvers has poor aesthetics. When the folding louvers are contracted, due to the angular limitation of the hinges, the folding louvers cannot be completely contracted together, resulting in a reduced degree of sunlight reception. The way the folding louvers are hinged to each other leads to a poor waterproof effect between curtain sheets and curtain sheets.

[0008] Preferably, at least two sets of light-shielding components are arranged inside the frame body, and a middle rail is arranged between adjacent two sets of light-shielding components.

[0009] Preferably, the frame body includes a front cover plate, side plates perpendicular to the front cover plate are respectively arranged on both sides of the front cover plate, a driving mechanism is arranged inside the front cover plate and the side plates, and connecting plates are respectively arranged on both sides of the front cover plate.

[0010] Preferably, the driving mechanism includes a winding roller, the winding roller is installed inside the front cover plate, pulleys are installed at both ends of the winding roller, the pulleys are located in the side plates, pulleys are arranged inside the ends of the two side plates far away from the front cover plate, and a rack is wound around between the two pulleys on the same side.

[0011] Preferably, a driving member is fixedly installed on the rack located on the upper layer. The driving member is used to drive the telescopic mechanism to telescope or expand. The driving member is located inside the side plate and can slide along the length direction inside the side plate.

[0012] Preferably, the telescopic joint includes a first telescopic piece and a second telescopic piece. The middle parts of the first telescopic piece and the second telescopic piece are rotationally assembled to form an X shape. Several telescopic joints are sequentially assembled to form a telescopic mechanism.

[0013] Preferably, the second telescopic piece on the telescopic joint at one end of the telescopic mechanism is fixedly connected to the connecting plate. A fixing plate is arranged on the first telescopic piece of the telescopic joint at the other end of the telescopic mechanism. The fixing plate is fixedly connected to the driving member.

[0014] Preferably, a compensation plate is further arranged on the first telescopic piece of the telescopic joints arranged with one telescopic joint interval. The compensation plate is a right trapezoid. The right-angled waist of the compensation plate is fixedly connected to the first telescopic piece.

[0015] Preferably, the curtain sheet is installed between two opposed compensation plates.

The second mounting holes correspond to the first mounting holes.

[0016] Preferably, a first hook plate and a second hook plate are further arranged on the curtain sheet. The opening directions of the first hook plate and the second hook plate are opposite. The first hook plate and the second hook plate are used to hook with the second hook plate and the first hook plate on the adjacent curtain sheet respectively.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present utility model provides a scissor-type waterproof folding awning, which has the following beneficial effects:

[0019] For this scissor-type waterproof folding awning, through the mutual cooperation of the frame body, the driving mechanism, the telescopic mechanism and the curtain sheet. The curtain sheet is separately installed on the compensation plate of one telescopic piece, so that the connection relationship between the curtain sheet and the adjacent curtain sheets becomes less. When disassembling and replacing, only the compensation plate connected to this curtain sheet needs to be disassembled, without considering the relationship between the adjacent curtain sheets and this curtain sheet. The disassembly and replacement are simpler, more efficient and more convenient.

[0020] When unfolding the curtain sheets, start the drive mechanism to make the winding roller rotate counterclockwise, thereby driving the pulleys on both sides to rotate. The rotation of the pulleys further drives the rack arranged between the two pulleys to rotate counterclockwise. Since the driving member is fixedly arranged on the rack, the driving member gradually moves away from the front cover plate from the end close to the front cover plate, and drives the curtain sheet farthest from the front cover plate to move away from the front cover plate through the fixing plate, thereby realizing the unfolding of the curtain sheet. During the unfolding process of the curtain sheet, the telescopic mechanism gradually unfolds from the tightened state, the telescopic mechanism is gradually stretched, and the curtain sheets installed on the compensation plate gradually rotate from the vertical state to the flat state. After the curtain sheets are unfolded, the adjacent curtain sheets are hooked together by the first hook plate and the second hook plate, so that all the curtain sheets form a sky curtain. When retracting the curtain sheets, start the drive mechanism to make the winding roller rotate clockwise, and drive the curtain sheets to move towards the front cover plate by the driving member, thereby realizing the retraction of the curtain sheets. Generally, a dimming effect similar to that of a shutter is formed, rather than the effect of unilateral unfolding and unilateral retraction of a traditional curtain, which is more aesthetically pleasing.

[0021] By installing the curtain sheets separately on the compensation plate of a telescopic sheet, that is, there is no hinge connection between the curtain sheets, the angle limitation due to the hinge connection between adjacent curtain sheets is eliminated. Therefore, when retracting the curtain sheets, the curtain sheets can be completely retracted to the vertical state and closely attached together, thereby greatly increasing the degree of sunlight reception.

[0022] After the curtain sheets are completely unfolded, the first hook plate and the second hook plate between adjacent curtain sheets will hook together. The first hook plate 42 and the second hook plate 43 on two adjacent curtain sheets 4 will rotate and hook together, thereby automatically realizing the cooperation between the curtain sheets 4 and the curtain sheets 4. At the same time, this hooking connection method also effectively prevents water leakage between the curtain sheets 4 and the curtain sheets 4, achieving an effective waterproof effect.

[0023] Thus, it is possible to remove the damaged curtain sheet without affecting adjacent curtain sheets, making disassembly and installation more convenient, making the dimming method more aesthetically pleasing, being able to completely retract the curtain sheets so that each curtain sheet is in a vertical state and closely attached together to increase the degree of sunlight reception and enhance the waterproof effect between the curtain sheets.

[0042] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0043] Please refer to Figures 1-11 , a scissor-type waterproof folding awning, which includes a frame body 1. The frame body 1, as a basic structure for carrying and fixing each component, has a reserved space inside for installing a set of light-shielding components 5. The light-shielding components 5 include two sets of opposed telescopic mechanisms 3 and a curtain sheet 4 installed between the two sets of telescopic mechanisms 3 to achieve the unfolding and contraction functions of the awning. A driving mechanism 2 is arranged inside the frame body 1. Two sets of telescopic mechanisms 3 are also oppositely arranged inside the frame body 1. The telescopic mechanisms 3 are cooperatively connected with the driving mechanism 2 and the frame body 1. The telescopic mechanism 3 is composed of multiple telescopic joints 31, and the curtain sheet 4 is installed on the telescopic joints 31. The telescopic mechanism 3 is composed of multiple telescopic joints 31. Through the mutual assembly between the telescopic joints 31, the awning is transformed from a vertical state to a flat state when unfolding and returns to the vertical state when contracting. The driving mechanism 2 is used to drive the telescopic mechanism 3 to contract and unfold. The driving mechanism 2 drives the telescopic mechanism 3 to expand or contract by controlling the rotation of the winding roller 21 and using the transmission mechanism of the belt pulley 23 and the rack 22, thereby controlling the unfolding and contraction of the curtain sheet 4.

[0044] At least two sets of light-shielding components 5 are arranged inside the frame body 1, and a middle rail 6 is arranged between two adjacent sets of light-shielding components 5. In order to adapt to different installation widths, at least two sets of juxtaposed light-shielding components 5 can be installed in the frame body 1, and at the same time, the number of corresponding front covers 11 is increased. In addition, a middle rail 6 is also arranged between every two adjacent light-shielding components 5 for carrying the part of the light-shielding component 5 located inside the frame body 1, such as Figure 11 . And these multiple juxtaposed light-shielding components 5 can realize the operation of multiple juxtaposed light-shielding components 5 driven by the same set of driving mechanism 2 by lengthening the length of the winding roller. That is, the width of the entire awning is widened on the premise of a set of driving mechanism 2.

[0045] The frame body 1 includes a front cover 11. Side plates 13 perpendicular to the front cover 11 are respectively arranged on both sides of the front cover 11, and the driving mechanism 2 is arranged inside the front cover 11 and the side plates 13. The front cover 11 and the two side plates 13 together form a U-shaped structure, and the middle of the U-shaped structure is used to install the curtain sheet 4 and receive sunlight. Spaces are reserved inside the front cover 11 and the side plates 13, and the driving mechanism 2 is installed.

[0046] The drive mechanism 2 includes a winding roller 21. The winding roller 21 is installed inside the front cover plate 11. Belt pulleys 23 are installed at both ends of the winding roller 21. The belt pulleys 23 are located in the side plates 13. Inside the ends of the two side plates 13 away from the front cover plate 11, there are belt pulleys 23. A rack 22 is wound around between the two belt pulleys 23 on the same side. The tent is driven by the rotation of the winding roller 21, and the rotation direction of the winding roller 21 determines the deployment or contraction of the telescopic mechanism 3. Specifically, when the winding roller 21 rotates counterclockwise, it pulls the telescopic mechanism 3 to deploy; conversely, when the winding roller 21 rotates clockwise, it pushes the telescopic mechanism 3 to contract through the same mechanism. The belt pulleys 23 are installed at both ends of the winding roller 21 and rotate coaxially with the winding roller 21. The main function of the belt pulleys 23 is to transmit the rotational motion of the winding roller 21 to the rack 22, thereby driving the rack 22 to move inside the side plates 13. The belt pulleys 23 and the rack 22 are connected by a toothed belt. This connection method can ensure the synchronous motion between the belt pulleys 23 and the rack 22 and transmit sufficient torque to drive the telescopic mechanism 3. The side plates 13 are part of the frame body 1. They are perpendicularly arranged with the front cover plate 11 and jointly form a space for installing the drive mechanism 2 and the telescopic mechanism 3. Inside the side plates 13, installation positions for transmission components such as the belt pulleys 23 and the rack 22 are set to ensure the stable operation of these components. In addition, the side plates 13 also play a role in supporting and protecting the transmission system, preventing external interference or damage. The rack 22 meshes with the toothed belt on the belt pulleys 23, converting the rotational motion of the belt pulleys 23 into linear motion. The rack 22 is installed inside the side plates 13 and is wound around between the two belt pulleys 23 on the same side. When the belt pulleys 23 rotate, the rack 22 will move along the length direction inside the side plates 13, thereby driving the driving member 24 fixedly installed on the rack 22 to move, so as to realize the deployment and contraction of the curtain sheet 4.

[0047] A driving member 24 is fixedly installed on the rack 22 located on the upper layer. The driving member 24 is used to drive the telescopic mechanism 3 to expand and contract or deploy. The driving member 24 is located inside the side plates 13 and can slide along the length direction inside the side plates 13. The linear motion of the rack 22 will directly drive the driving member 24 to slide along the length direction inside the side plates 13. The driving member 24 is connected to the first telescopic piece 311 of the telescopic joint 31 away from the front cover plate 11 through a fixing plate 33. Therefore, when the driving member 24 slides, it can drive the telescopic mechanism 3 to expand and contract or deploy, and finally drive the curtain sheet 4 to contract or deploy.

[0048] The expansion joint 31 includes a first expansion piece 311 and a second expansion piece 312. The middle parts of the first expansion piece 311 and the second expansion piece 312 are rotationally assembled to form an X shape. Several expansion joints 31 are sequentially assembled to form the expansion mechanism 3. The first expansion piece 311 and the second expansion piece 312 are the basic components of the expansion joint 31, and they have sufficient rigidity and toughness to withstand the stress and deformation during the unfolding and contraction of the awning. The middle parts of the first expansion piece 311 and the second expansion piece 312 are connected by rotational assembly, enabling them to rotate relative to each other around a common axis point. This allows the expansion joint 31 to vary in different lengths, thereby permitting the entire expansion mechanism 3 to perform expansion and contraction movements. The mutual assembly between the expansion joints 31 allows them to be sequentially connected and form a longer expansion mechanism 3. When multiple expansion joints 31 are sequentially assembled with each other, they can work together to achieve a larger expansion range. When the driving mechanism 2 drives the expansion mechanism 3, the relative rotation and expansion between the expansion joints 31 enable the entire expansion mechanism 3 to gradually unfold or contract, thereby changing the covering area and shape of the awning.

[0049] On both sides of the front cover plate 11, connecting plates 12 are respectively provided. When the expansion mechanism 3 expands and contracts, one end of it should be fixed. By fixedly connecting the second expansion piece 312 on the expansion joint 31 close to the front cover plate 11 to the connecting plate 12, the stable expansion and contraction of the expansion mechanism 3 can be ensured.

[0050] The second expansion piece 312 on the expansion joint 31 at one end of the expansion mechanism 3 is fixedly connected to the connecting plate 12. The connecting plate 12 is a fixed structure installed on both sides of the front cover plate 11. The fixed connection between the second expansion piece 312 and the connecting plate 12 means that the expansion joint 31 at this end is firmly fixed to one end of the front cover plate 11 and cannot move or rotate freely. This ensures a stable base point for the expansion mechanism 3 during unfolding and contraction. On the first expansion piece 311 of the expansion joint 31 at the other end of the expansion mechanism 3, a fixing plate 33 is provided, and the fixing plate 33 is fixedly connected to the driving part 24. The fixing plate 33 is a plate-like structure installed on the first expansion piece 311 of the expansion joint 31 at the end of the expansion mechanism 3 for fixedly connecting to the driving part 24. This enables the expansion mechanism 3 to be effectively connected to the driving part 24, thereby ensuring that the driving part 24 can drive the expansion mechanism 3 to contract and expand.

[0051] On the first expansion sheet 311 of the expansion joints 31 arranged with one expansion joint 31 in between, there is also a compensation plate 313. The compensation plate 313 is a right trapezoid. The right-angled waist of the compensation plate 313 is fixedly connected to the first expansion sheet 311. There are also two first mounting holes 314 on the compensation plate 313. The connection line between the two first mounting holes 314 is parallel to the inclined waist of the compensation plate 313. During installation, the second mounting holes 41 on the curtain sheet 4 are aligned with the two first mounting holes 314 for installation. Since the expansion structure consists of several expansion joints 31, when the expansion degree of the expansion joint 31 reaches the limit, there is still a certain angle between the first expansion sheet 311 and the second expansion sheet 312. Therefore, the curtain sheet 4 cannot be arranged parallel to the first expansion sheet 311. Once the curtain sheet 4 is arranged parallel to the first expansion sheet 311, then the curtain sheet 4 cannot be unfolded into a flat state. Therefore, through the trapezoidal setting of the compensation plate 313, there is a certain angle between the curtain sheet 4 and the first expansion sheet 311, that is, the angle between the inclined waist of the trapezoid and the first expansion sheet 311, which exactly compensates for the angle difference generated by the structures of the first expansion sheet 311 and the second expansion sheet 312, so that when the curtain sheet 4 is fully unfolded, it can be completely flattened. On the first expansion sheet 311 provided with the compensation plate 313, there is also a pulley 32, and the pulley 32 is located in the side plate 13. The pulley 32 is used to limit the sliding path of the expansion mechanism 3 and support the curtain sheet 4 from both sides of the curtain sheet 4 to prevent the curtain sheet 4 from collapsing.

[0052] The curtain sheet 4 is installed between two opposing compensation plates 313. There are two second mounting holes 41 respectively arranged inside the two sides of the curtain sheet 4 in contact with the expansion mechanism 3. The second mounting holes 41 correspond to the first mounting holes 314. The curtain sheet 4 is the main covering, used to provide sunshade, wind protection or decoration, etc. The curtain sheet 4 is installed between two opposing compensation plates 313, and can be stretched and unfolded when the expansion mechanism 3 is unfolded, and folded and retracted when contracted, so as to keep the awning flat and beautiful. The second mounting holes 41 are the holes arranged inside the two sides of the curtain sheet 4 in contact with the expansion mechanism 3, and correspond to the first mounting holes 314. The main function of the second mounting holes 41 is to provide a fixed point for the connection between the curtain sheet 4 and the expansion mechanism 3. By connecting the first mounting holes 314 and the second mounting holes 41 with screws, it can be ensured that the curtain sheet 4 can move synchronously with the expansion and contraction of the expansion mechanism 3.

[0053] Hook plate one 42 and hook plate two 43 are also provided on the curtain sheet 4. The opening directions of hook plate one 42 and hook plate two 43 are opposite. Hook plate one 42 and hook plate two 43 are used to engage with hook plate two 43 and hook plate one 42 on the adjacent curtain sheet 4 respectively. When the curtain sheet 4 gradually rotates from the vertical state to the unfolded state, the distance between each curtain sheet 4 will become closer and closer. To ensure the connection between curtain sheet 4 and curtain sheet 4, hook plate one 42 and hook plate two 43 on two adjacent curtain sheets 4 will rotate and engage with each other, thus automatically realizing the cooperation between curtain sheet 4 and curtain sheet 4. At the same time, this engaging connection method also effectively prevents water leakage between curtain sheet 4 and curtain sheet 4, achieving an effective waterproof effect.

[0054] Working principle: The curtain sheet 4 is separately installed on the compensation plate 313 of a telescopic sheet, reducing the connection relationship between the curtain sheet 4 and the adjacent curtain sheet 4. When demolishing and replacing, only the compensation plate 313 connected to this curtain sheet 4 needs to be removed, without considering the relationship between the adjacent curtain sheet 4 and this curtain sheet 4. Demolition and replacement are simpler, more efficient, and more convenient.

[0055] When unfolding the curtain sheet 4, start the driving mechanism 2, so that the winding roller 21 rotates counterclockwise, thereby driving the belt wheels 23 on both sides to rotate. The rotation of the belt wheels 23 further drives the rack 22 arranged between the two belt wheels 23 to rotate counterclockwise. Since the driving part 24 is fixedly arranged on the rack 22, the driving part 24 gradually moves away from the front cover plate 11 from the end close to the front cover plate 11, and drives the curtain sheet 4 farthest from the front cover plate 11 to move away from the front cover plate 11 through the fixing plate 33, thus realizing the unfolding of the curtain sheet 4. During the unfolding process of the curtain sheet 4, the telescopic mechanism 3 gradually unfolds from the tightened state, the telescopic mechanism 3 is gradually stretched, and the curtain sheet 4 installed on the compensation plate 313 gradually rotates from the vertical state to the unfolded state. After the curtain sheet 4 is unfolded, the adjacent curtain sheets 4 are engaged with each other through hook plate one 42 and hook plate two 43, so that all the curtain sheets 4 form a sky curtain. When contracting the curtain sheet 4, start the driving mechanism 2, so that the winding roller 21 rotates clockwise, and the driving part 24 drives the curtain sheet 4 to move towards the direction close to the front cover plate 11, thus realizing the contraction of the curtain sheet 4. Generally, it forms a dimming effect similar to that of a shutter, rather than the effect of unilateral unfolding and unilateral contraction of a traditional curtain, which is more aesthetic.

[0056] By separately installing the curtain sheet 4 on the compensation plate 313 of a telescopic sheet, that is, there is no hinge connection between the curtain sheet 4 and the curtain sheet 4, eliminating the angular limitation due to the hinge connection between the adjacent curtain sheets 4. Therefore, when contracting the curtain sheet 4, the curtain sheet 4 can be completely contracted to the vertical state and closely attached together, thereby greatly increasing the degree of receiving sunlight.

[0057] After the curtain blades 4 are fully unfolded, the first hook plate 42 and the second hook plate 43 between adjacent curtain blades 4 will be hooked together. The first hook plate 42 and the second hook plate 43 on two adjacent curtain blades 4 will be rotationally hooked together, thus automatically realizing the cooperation between curtain blades 4 and curtain blades 4. At the same time, this hooking connection method also effectively prevents water leakage between curtain blades 4 and achieves an effective waterproof effect.
