Description

Technical Field

[0001] This utility model relates to the field of outdoor facilities technology, specifically to a novel chain-driven folding rainproof awning. Background Technology

[0002] Currently, folding slat canopies are widely used in architectural shading and ceilings, with their core function being to achieve shading or ventilation adjustment through the unfolding and folding of the slats. Existing technologies often employ a structure where synchronous belts are embedded within the side beams, using these belts to pull the front support beam, thereby opening and closing the slats.

[0003] However, this type of structure has significant drawbacks: First, the timing belt needs to be precisely installed inside the side beam and connected to the drive pulley and front trailing beam at multiple points. Tension must be repeatedly adjusted during assembly; otherwise, misalignment or jamming can easily occur, leading to low production efficiency. Second, the timing belt is prone to fatigue, elongation, and even breakage under prolonged tension, especially under high temperature or high load conditions, significantly shortening its lifespan and requiring frequent replacement, resulting in high maintenance costs. Furthermore, friction between the timing belt and the metal side beam may generate abnormal noise, affecting the user experience.

[0004] Therefore, there is an urgent need for a new type of drive solution that can simplify the structure and improve durability while retaining the function of synchronous motion. Utility Model Content

[0005] This utility model provides a novel chain-driven folding rainproof awning. Through the coordinated design of rigid transmission of chain and sprocket, electric sliding rail power supply, and multi-track guidance, it solves the pain points of traditional synchronous belt awnings such as poor durability, complex assembly, and easy failure. It has high reliability, low maintenance cost and intelligent potential, and is suitable for harsh working conditions such as outdoor construction.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel chain-driven folding rainproof awning, comprising: a frame, the frame consisting of a pair of side beams, and a tail beam and a front beam connected to the ends of the two side beams; an upper slide rail, a middle slide rail, and a lower slide rail are respectively provided along the length direction on opposite sides of the two side beams; an electric slide rail is provided at the top of any one of the upper slide rails along the length direction; and chains are fixedly provided along the length direction in the two middle slide rails; a front support beam located within the frame, and stabilizing pulleys that cooperate with the upper slide rail and the lower slide rail are respectively provided at both ends of the front support beam; and further provided at both ends of the front support beam. The system includes a shaft head extending into the middle slide rail, with a motor inside to drive both shaft heads. Each shaft head has a sprocket that meshes with the chain. The top of the front support beam has a first brush that cooperates with the electric slide rail. The motor is electrically connected to the first brush. A folding curtain is formed by multiple curtain panels hinged together, with both ends of the folding curtain hinged to the outer walls of the front support beam and the tail beam, respectively. The folding curtain also has hanging wheels on both sides that cooperate with the upper slide rail. A controller is provided, which includes a wireless receiving module and a remote control adapted to the wireless receiving module. The electric slide rail is electrically connected to the controller.

[0007] Preferably, the slats are hinged to each other by an upper hinge bar and a lower hinge bar; the bottom of the upper hinge bar has upper circular grooves on both sides along the length direction, and the top of each slat has an upper circular shaft that is hinged to the upper circular groove; the top of the lower hinge bar has lower circular shafts on both sides along the length direction, and the bottom of each slat has a lower circular groove that is fitted to the lower circular shaft.

[0008] Preferably, each of the lower hinge strips has a first water guide groove along its length at the top, each of the side beams has a second water guide groove in the extension direction corresponding to the bottom of both sides of the folding curtain, and the front beam has a third water guide groove along its length, the third water guide groove being located at the bottom of the two second water guide grooves.

[0009] Preferably, a first light strip is embedded in the outer wall of each of the second water guide channels, and the first light strip is electrically connected to the controller; a second light strip is embedded in the bottom of each of the upper hinge strips, and a second brush that cooperates with the electric slide rail is provided at the top, and the second light strip is electrically connected to the second brush.

[0010] Preferably, the front trailing beam is provided with a shaft connecting the two shaft heads, the shaft is provided with a driven gear in the middle, and the motor output shaft is provided with a driving gear that meshes with the driven gear.

[0011] Preferably, the motor is a dual-output shaft geared motor, and the two output shafts of the motor are respectively connected to the corresponding shaft heads.

[0012] The beneficial effects of this utility model are as follows: This technical solution, through the coordinated design of rigid transmission of chains and sprockets, electric slide rail power supply, and multi-slide guide, solves the pain points of traditional synchronous belt canopies, such as poor durability, complex assembly, and easy failure. It also has high reliability, low maintenance costs, and intelligent potential, making it suitable for harsh working conditions such as outdoor construction. During the unfolding and retraction of the folding curtain driven by the front trailing beam, its internal motor drives the driven gear on the shaft through the active gear, driving the sprockets on both ends of the shaft to rotate. The sprockets mesh with the chain fixed in the slide rail in the side beam, forming a sprocket and chain transmission mechanism, realizing the movement of the front trailing beam along the side beam. This process is rigidly connected to the sprockets on both sides by a shaft, ensuring that the two shafts rotate synchronously and avoiding the deviation problem caused by uneven tension in traditional synchronous belts. The electric slide rail at the top of the slide rail on the side beam contacts the first brush at the top of the front trailing beam, providing continuous power to the motor without the need for additional wiring. The stabilizing pulleys at both ends of the front support beam are embedded in the upper and lower tracks of the side beam, respectively, limiting lateral displacement. The hanging wheels on both sides of the folding curtain roll within the upper track, assisting in supporting the curtain slats and allowing them to unfold or fold smoothly. Users send commands via remote control; the controller receives the signal and adjusts the power supply to the electric slide rail, controlling the motor's forward and reverse rotation to open and close the curtain slats. Because the metal chain has high tensile strength, high temperature resistance, and fatigue resistance, its lifespan is significantly longer than that of a synchronous belt, reducing the risk of breakage and maintenance frequency. The shaft forces synchronization with the sprockets on both sides, completely solving the problems of deviation and jamming, and reducing debugging difficulty. The chain is fixed within the middle slide rail, eliminating the need for tension adjustment; the electric slide rail integrates power supply, eliminating the need for traditional cable routing. The noise from the metal chain meshing with the sprockets is lower than that from the friction of the synchronous belt against the side beam, improving quietness. The upper and lower tracks constrain the front support beam, and the hanging wheels support the folding curtain, ensuring a smooth movement trajectory and stronger wind pressure resistance. The motor transmits power through a gear set, which is more efficient than belt drives and consumes less energy. The upper and lower hinge strips are designed to create a hinged structure for multiple curtain slats. The upper circular groove and upper circular shaft work together to allow the folding curtain to rotate smoothly during unfolding and folding, preventing jamming. The lower circular shaft and lower circular groove form a stable hinge point, ensuring the curtain slats remain aligned during movement and preventing misalignment or twisting. This design makes the connection between curtain slats stronger, the folding and unfolding process smoother, and reduces mechanical wear. Furthermore, the first water guide channel is located at the lower connection of adjacent curtain slats to collect rainwater flowing from the surface of the curtain slats, preventing water from seeping into the hinged structure. The second water guide channel is set along the length of the side beam, receiving rainwater flowing from both sides of the curtain slats and guiding the water to the front end of the frame at the set tilt angle. The third water guide channel is located below the two second water guide channels, serving as a water collection channel to uniformly guide rainwater to designated drainage points, such as building drainage pipes. This three-stage water guiding system prevents rainwater accumulation or leakage, improves waterproof performance, effectively prevents water droplets from entering the internal structure of the canopy, and extends its service life. The drainage channel system ensures that rainwater is drained quickly, preventing water accumulation from corroding metal parts or affecting motor operation.Furthermore, the dual-axis hinge and first water guide channel design enhance overall rigidity, making it suitable for outdoor windy and rainy environments, reducing problems such as component corrosion and curtain deformation caused by rainwater infiltration, and lowering maintenance costs.

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a novel chain-driven folding rainproof awning includes: a frame consisting of a pair of side beams 1, and a tail beam 2 and a front beam 3 connected to the ends of the two side beams 1. On opposite sides of the two side beams 1, an upper slide rail 5, a middle slide rail 6, and a lower slide rail 7 are respectively provided along the length direction. An electric slide rail 4 is provided at the top of any one of the upper slide rails 5 along the length direction. Chains 8 are fixedly installed along the length direction within each of the two middle slide rails 6. A front support beam 9 is located within the frame, and both ends of the front support beam 9 are respectively provided with stabilizing pulleys that cooperate with the upper slide rail 5 and the lower slide rail 7. 10. The front trailing beam 9 is provided with shaft heads 12 extending into the middle slide rail 6 at both ends. A motor 13 is provided inside to drive the two shaft heads 12. Each shaft head 12 is provided with a sprocket 11 that meshes with the chain 8. The top of the front trailing beam 9 is provided with a first brush 14 that cooperates with the electric slide rail 4. The motor 13 is electrically connected to the first brush 14. The front trailing beam 9 is provided with a shaft 30 that connects the two shaft heads 12. A driven gear 31 is provided in the middle of the shaft 30. The output shaft of the motor 13 is provided with a driving gear 32 that meshes with the driven gear 31. The folding curtain 15 is formed by hinged multiple curtain panels 16, and both ends of the folding curtain 15 are respectively hinged to the outer wall of the front support beam 9 and the tail beam 2. The two sides of the folding curtain 15 are also provided with hanging wheels 17 that cooperate with the upper slide rail 5; the controller is provided with a wireless receiving module and a remote control adapted to the wireless receiving module, and the electric slide rail 4 is electrically connected to the controller.

[0024] This technical solution solves the pain points of traditional synchronous belt canopies, such as poor durability, complex assembly, and easy failure, through the rigid transmission of chain 8 and sprocket 11, power supply of electric slide rail 4, and multi-slide guide design. It has high reliability, low maintenance cost and intelligent potential, and is suitable for harsh working conditions such as outdoor construction.

[0025] During the unfolding and retraction of the folding curtain 15 driven by the front support beam 9, its internal motor 13 drives the driven gear 31 on the shaft 30 through the driving gear 32, which in turn drives the sprockets 11 on the two end shafts 12 to rotate. The sprockets 11 mesh with the chain 8 fixed in the slide rail 6 in the side beam 1, forming a sprocket 11 and chain 8 transmission mechanism, enabling the front support beam 9 to move along the side beam 1. This process is rigidly connected to the two sprockets 11 by a shaft 30, ensuring that the two shafts 12 rotate synchronously, avoiding the deviation problem caused by uneven tension of traditional synchronous belts. The electric slide rail 4 at the top of the upper slide rail 5 of the side beam 1 contacts the first brush 14 at the top of the front support beam 9, providing continuous power to the motor 13 without the need for additional wiring. The stabilizing pulleys 10 at both ends of the front support beam 9 are respectively embedded in the upper slide rail 5 and the lower slide rail 7 of the side beam 1, limiting lateral displacement; the hanging wheels 17 on both sides of the folding curtain 15 roll in the upper slide rail 5, assisting in the support of the curtain slats 16, so that it can unfold or fold smoothly. The user sends a command via remote control. After receiving the signal, the controller adjusts the power supply to the electric slide rail 4, controls the motor 13 to rotate forward and backward, and realizes the opening and closing of the folding curtain 15.

[0026] The metal chain 8 boasts high tensile strength, resistance to high temperatures and fatigue, and a significantly longer lifespan than synchronous belts, reducing the risk of breakage and maintenance frequency. The shaft 30 forces synchronization with the sprockets 11 on both sides, completely resolving issues of misalignment and jamming, and reducing adjustment difficulty. The chain 8 is fixed within the central slide rail 6, eliminating the need for tension adjustment; the electric slide rail 4 integrates power supply, eliminating the need for traditional cable routing. The meshing noise between the metal chain 8 and the sprockets 11 is lower than that of the friction beam 1 of the synchronous belt, improving quietness. The upper slide rail 5 and lower slide rail 7 constrain the front trailing beam 9, and the hanging wheel 17 supports the folding curtain, ensuring a smooth movement trajectory and stronger wind pressure resistance. The motor 13 transmits power through a gear set, achieving higher efficiency and lower energy consumption than belt drives.

[0027] Furthermore, the curtain slats 16 are hinged to each other via upper hinge strips 18 and lower hinge strips 19. The upper hinge strips 18 have upper circular grooves 20 on both sides of their bottom along their length, and each curtain slat 16 has an upper circular shaft 21 at its top that hinges to the upper circular grooves 20. The lower hinge strips 19 have lower circular shafts 22 on both sides of their top along their length, and each curtain slat 16 has a lower circular groove 23 at its bottom that mates with the lower circular shaft 22. Each lower hinge strip 19 has a first water guide groove 24 at its top along its length, each side beam 1 has a second water guide groove 25 extending along its length from the bottom of each side of the folding curtain 15, and the front beam 3 has a third water guide groove 26 along its length, the third water guide groove 26 being located at the bottom of the two second water guide grooves 25.

[0028] In this technical solution, the hinge structure of multiple curtain slats 16 is achieved through the design of the upper hinge strip 18 and the lower hinge strip 19. The cooperation between the upper circular groove 20 and the upper circular shaft 21 allows the folding curtain 15 to rotate smoothly during unfolding and folding, avoiding jamming. The lower circular shaft 22 and the lower circular groove 23 form a stable hinge point, ensuring that the curtain slats 16 remain aligned during movement, preventing misalignment or twisting. This design makes the connection between the curtain slats 16 more robust, the folding and unfolding process smoother, and reduces mechanical wear. Furthermore, the first water guide channel 24 is located at the lower connection of adjacent curtain slats 16, used to collect rainwater flowing from the surface of the curtain slats 16, preventing water from seeping into the hinge structure. The second water guide channel 25 is set along the length of the side beam 1, receiving rainwater flowing from both sides of the curtain slats 16, and guiding the water to the front end of the frame under the set tilt angle of the frame. The third water guide channel 26 is located below the two second water guide channels 25, serving as a water collection channel to uniformly guide rainwater to a designated drainage point, such as a building drainage pipe. This three-stage water-guiding system prevents rainwater accumulation or leakage, improves waterproof performance, effectively prevents water droplets from entering the internal structure of the canopy, and extends its service life. The water-guiding channel system ensures that rainwater is quickly discharged, preventing water accumulation from corroding metal components or affecting the operation of motor 13. Furthermore, the dual-axis hinge and the first water-guiding channel design enhance overall rigidity, making it suitable for outdoor windy and rainy environments, reducing problems such as component corrosion and curtain slat deformation caused by rainwater infiltration, and lowering maintenance costs.

[0029] Each of the second water guide channels 25 has a first light strip 27 embedded in its outer wall, and the first light strip 27 is electrically connected to the controller; each of the upper hinge bars 18 has a second light strip 28 embedded in its bottom and a second brush 29 that cooperates with the electric slide rail 4 at its top, and the second light strip 28 is electrically connected to the second brush 29.

[0030] This design innovatively integrates the lighting system with the mechanical structure, which not only solves the problem of the traditional canopy's single function at night, but also enhances the user experience through intelligent control, while maintaining the original waterproof and durable performance characteristics, achieving a perfect combination of functionality and aesthetics.

[0031] As a preferred embodiment, the motor 13 is a dual-output shaft reduction motor, and the two output shafts of the motor 13 are respectively connected to the corresponding shaft heads 12.

[0032] In addition, such as Figure 7 As shown, in this embodiment, the chain 8 and sprocket 11 can be replaced by a track rack 34 and a travel gear 33. The rigid structure of the track rack 34 can further reduce the assembly difficulty and the cost of the device, while also ensuring the synchronous and silent movement of the front trailing beam 9.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
