Description

Technical Field

[0001] This utility model belongs to the field of skylight pavilion technology, specifically relating to a roll-up sunshade. Background Technology

[0002] Sunshade products are gradually moving towards the era of intelligence, achieving opening and closing through remote control, timer control, and voice control. In the future, sunshade products will place greater emphasis on intelligent and digital development, such as being equipped with Bluetooth connectivity, automatic opening and closing, and GPS positioning functions to further enhance the user experience.

[0003] Patent publication number CN117822952A discloses a retractable waterproof gazebo, comprising a gazebo body and a folding canopy curtain located at the center of the top of the gazebo body. A drive unit is located on one side of the top of the gazebo body. The drive structure includes a dual-head motor and two drive wheels, both of which are fixedly connected to the drive ends of the dual-head motor. Each drive wheel is meshed with a synchronous belt. The folding canopy curtain includes a drive rod, curtain blades, a moving link, and a sliding rod. The bottom of each pair of curtain blades is rotatably connected to the moving link, and the end of each curtain blade away from the moving link is rotatably connected to the sliding rod. The dual-head motor drives the synchronous belt via the drive wheels, causing a fixed block to slide at the top of the gazebo body. The sliding of the fixed block moves the drive rod, which in turn moves the folding canopy curtain as it expands and contracts, making the gazebo flexible to use.

[0004] However, the current roll-up sunshade has the following problems: similar products on the market often have complex structures, connecting the blades through "X-shaped" hinges, with rigid contact and no elastic compensation, resulting in unstable operation after long-term use, and requiring regular dust cleaning and lubrication every year. Therefore, we have proposed a roll-up sunshade. Utility Model Content

[0005] The purpose of this invention is to provide a roll-up sunshade that solves the problems of similar products on the market, which often have complex structures, connect blades with "X-shaped" hinges, have rigid contact without elastic compensation, are unstable in long-term use, and require regular dust cleaning and lubrication every year.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A roll-up awning includes a supporting frame assembly. A drive system assembly is fixedly connected to a fixed end of the frame assembly. A transmission system assembly for transmitting kinetic energy is provided at the fixed end of the frame assembly. A traction rod is fixedly connected to a movable end of the transmission system assembly. A waterproof connecting rod is rotatably connected to the side of the traction rod. A venetian blind is rotatably connected to the side of the waterproof connecting rod. An anti-slip connecting rod is rotatably connected to the side of the venetian blind away from the waterproof connecting rod. A pulley is rotatably connected to the side of the anti-slip connecting rod.

[0008] The supporting canopy frame assembly includes four foot plates, each foot plate has a foot plate cover fixedly connected to its top, each foot plate cover has a foot tube fixedly connected to its top, each foot tube has a foot tube liner fixedly connected to its top, each foot tube liner has a crossbeam insert fixedly connected to its side, each crossbeam insert has a foot tube cover plate fixedly connected to its top, a square frame is fixedly connected between the four crossbeam inserts, the square frame has a square frame cover plate fixedly connected to its top, and a light strip is fixedly connected to the bottom of the square frame.

[0009] The drive system components include a solar panel, the bottom of which is fixedly connected to the top of a square frame cover plate. An output shaft is rotatably connected to the side of the crossbeam insert. A drive motor is fixedly connected to the circumferential surface of the output shaft. A pulley is fixedly connected to the bottom of the square frame and to the circumferential surface of the output shaft.

[0010] Two small clamping plates are fixedly connected to both sides of the square frame, and two pulleys are fixedly connected to the sides of the two small clamping plates. An H-type synchronous track is connected between the two pulleys for transmission.

[0011] The venetian blinds are connected in a "W" shape, with the four legs arranged in pairs, and the height of one pair of legs being 10 centimeters lower than that of the other pair.

[0012] The pulley contacts the H-shaped synchronous track, and the louvered slats are made of aluminum alloy.

[0013] The top of the square frame is equipped with a cleaning device, which includes a screw support. The bottom of the screw support is fixedly connected to the top of the square frame. A screw motor is fixedly connected to the side of the screw support. A threaded rod is fixedly connected to the output end of the screw motor. A scraper is threaded onto the threaded surface of the threaded rod. A support block is fixedly connected to the top of the square frame. A sliding rod is fixedly connected to the side of the support block. The side of the scraper passes through and slides on the circumferential surface of the sliding rod. A receiving button is fixedly connected to the inner wall of the square frame. A scale groove is opened on the side of the square frame.

[0014] The receiving button is located on the movement trajectory of the traction rod, and the bottom of the scraper is serrated and adapted to the shape of the unfolded venetian blind.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This utility model, through the arrangement of the transmission system assembly, enables the drive motor, pulleys, small clamps, traction rods, H-type synchronous tracks, cover, light strips, waterproof connecting rods, venetian blinds, anti-slip connecting rods, and pulleys to cooperate. The sliding of the venetian blinds drives the sliding of the waterproof connecting rods, allowing the venetian blinds to unfold under the force of the anti-slip connecting rods and the waterproof connecting rods for sun shading. The pulley-type transmission has stability over long distances, second only to chain transmission. The H-type synchronous track and pulleys have flexible contact, which does not require high manufacturing precision, ensures stable operation, low cost, high durability, and long service life, and avoids the need for annual track cleaning and lubrication.

[0017] This utility model, through the setting of a cleaning and scraping device, enables the screw bracket, screw motor, threaded rod, scraper, support block, slide rod, and receiving button to work together. The rotation of the threaded rod causes the scraper to move back and forth with the assistance of the slide rod. When the scraper moves left and right, it scrapes away dirt and attachments on the venetian blinds, preventing the device components from jamming due to dirt later. Attached Figure Description

[0029] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0030] like Figure 1-5 As shown, a roll-up sunshade includes a frame assembly 37 for support. A drive system assembly 38 is fixedly connected to the fixed end of the frame assembly 37. A transmission system assembly 39 for transmitting kinetic energy is provided at the fixed end of the frame assembly 37. The frame assembly 37 provides effective support and a stable structure, ensuring stable output of the drive system assembly 38 and the transmission system assembly 39. A traction rod 22 is fixedly connected to the moving end of the transmission system assembly 39. A waterproof connecting rod 32 is rotatably connected to the side of the traction rod 22. A venetian blind slat 33 is rotatably connected to the side of the venetian blind slat 33 away from the waterproof connecting rod 32. An anti-slip connecting rod 34 is rotatably connected to the side of the anti-slip connecting rod 34. A pulley 35 is rotatably connected to the side of the anti-slip connecting rod 34. The anti-slip connecting rod 34 and the waterproof connecting rod 32 not only provide effective waterproof conditions for the venetian blind slat 33 after it is unfolded, but also ensure that it will not become dislodged or slippery after unfolding.

[0031] The supporting frame assembly 37 includes four foot plates 1, each foot plate 1 has a foot plate cover 2 fixedly connected to its top, each foot plate cover 2 has a foot tube 3 fixedly connected to its top, and each foot tube 3 has a foot tube liner 5 fixedly connected to its top. The foot tube liner 5 is inserted between the foot tube 3 and the square frame 11 when fixed, which greatly improves the fit and stability between the square frame 11 and the foot tube 3. Each side of the four foot tube liner 5 has a crossbeam insert 7 fixedly connected to its side, and each crossbeam insert 7 has a foot tube cover plate 8 fixedly connected to its top. A square frame 11 is fixedly connected between the four crossbeam inserts 7, and a square frame cover plate 13 is fixedly connected to its top. The square frame cover plate 13 can reduce the vibration load on the main device when the device is working and ensure the safe output conditions of the device. A light strip 30 is fixedly connected to the bottom of the square frame 11.

[0032] The drive system component 38 includes a solar panel 10, the bottom of which is fixedly connected to the top of the square frame cover plate 13. The side of the crossbeam insert 7 is rotatably connected to an output shaft 12. A drive motor 14 is fixedly connected to the circumferential surface of the output shaft 12. The bottom of the square frame 11 is fixedly connected to a pulley 18, and the circumferential surface of the output shaft 12 is fixedly connected to the pulley 18. The solar panel 10 can convert solar energy into electrical energy, which not only provides power to the drive motor 14, but also greatly reduces the cost of use.

[0033] Two small clamping plates 19 are fixedly connected to both sides of the square frame 11. Two pulleys 18 are fixedly connected to the sides of the two small clamping plates 19. An H-type synchronous track 25 is connected between the two pulleys 18. The H-type synchronous track 25 can provide stable and uniform output conditions for the two pulleys 18, ensuring that the venetian blinds 33 will not be misaligned during operation.

[0034] The Venetian blind slats 33 are connected in a "W" shape, with the four legs 3 arranged in pairs. One pair of legs 3 is 10 centimeters lower than the other pair. This "W" shape connection effectively increases the stability between the slats, making them more secure. Especially in environments with strong winds or frequent adjustments, the "W" shape connection effectively prevents the slats from shifting or falling, maintaining the stability of the overall structure.

[0035] The pulley 35 contacts the H-type synchronous track 25. The louver slat 33 is made of aluminum alloy. A dense aluminum oxide film can easily form on the surface of the aluminum alloy. This film can effectively prevent further damage to the material by corrosive factors such as oxygen and moisture.

[0036] According to the above structure, when the drive motor 14 is turned on, the drive motor 14 drives the output shaft 12 to rotate. The rotation of the output shaft 12 drives the two pulleys 18 to rotate, which in turn drives the H-type synchronous track 25 to rotate. The rotation of the H-type synchronous track 25 drives the traction rod 22 to slide towards the receiving button 3608. The sliding of the traction rod 22 drives the anti-slip link 34 to slide, which in turn drives the venetian blind slats 33 to slide. The sliding of the venetian blind slats 33 drives the waterproof link 32 to slide, so that the venetian blind slats 33 unfold under the force of the anti-slip link 34 and the waterproof link 32 to perform sunshade operations (such as...). Figure 4 As shown), the stability of belt drive over long distances is second only to chain drive. The H-type synchronous track 25 and pulley 18 have flexible contact, which does not require high manufacturing precision, is stable in operation, low in cost, high in durability, long in service life, and avoids the problem of needing to clean the track and apply lubricant every year.

[0037] like Figure 1-5 As shown, a cleaning device 36 is provided on the top of the square frame 11. The cleaning device 36 includes a screw bracket 3601, the bottom of which is fixedly connected to the top of the square frame 11. A screw motor 3602 is fixedly connected to the side of the screw bracket 3601. A threaded rod 3603 is fixedly connected to the output end of the screw motor 3602. A scraper 3604 is threaded onto the threaded surface of the threaded rod 3603. The scraper 3604 can effectively scrape away the dirt attached to the venetian blind slats 33, ensuring the cleanliness of the venetian blind slats 33. For normal use of 3, a support block 3605 is fixedly connected to the top of the square frame 11, and a sliding rod 3607 is fixedly connected to the side of the support block 3605. The side of the scraper 3604 passes through and is slidably connected to the circumferential surface of the sliding rod 3607. A receiving button 3608 is fixedly connected to the inner wall of the square frame 11. A dirt groove 40 is opened on the side of the square frame 11. When the dirt on the louver slat 33 is scraped off by the scraper 3604, it is discharged through the scraper 3604 to prevent the dirt scraped off from accumulating on its surface and becoming unmanageable.

[0038] The receiving button 3608 is located on the movement trajectory of the traction rod 22. The bottom of the scraper 3604 is serrated and matches the shape of the unfolded venetian blind 33. When the traction rod 22 collides and squeezes the receiving button 3608, it opens the cleaning device 36, so that the cleaning device 36 can effectively clean without manual operation.

[0039] According to the above structure, when the traction rod 22 slides and contacts the receiving button 3608, the receiving button 3608 will turn on the screw motor 3602. The output end of the screw motor 3602 rotates, driving the threaded rod 3603 to rotate. The rotation of the threaded rod 3603 causes the scraper 3604 to move back and forth with the assistance of the slide rod 3607. When the scraper 3604 moves left and right, it scrapes off the dirt and attachments on the venetian blind slats 33 and discharges them through the lower dirt trough 40, avoiding the device components from jamming due to dirt in the later stage.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
