Description

Technical Field

[0001] This invention relates to the field of sunshade device technology, and more particularly to an adjustable sunshade device for building skylights. Background Technology

[0002] Most existing traditional residential skylights do not have sunshade devices installed. As a result, the direct sunlight entering through the skylight turns the interior into a huge greenhouse, reducing indoor thermal comfort and resulting in a poor experience for residents. Currently, there are two main types of pitched roof skylights on the market with sunshade devices. One type is a manual sunshade device, which is equipped with adjustable components such as louvers and sunshade cloth. It has a simple structure, various patterns, and is easy to install. The other type is an electric sunshade device, which has an adjustable sunshade panel device installed inside or outside.

[0003] An existing adjustable skylight shading device for traditional residential buildings (publication number: CN109098361A) has at least the following drawbacks:

[0004] When the above-mentioned patent is used, the synthetic resin tile components are adjusted through a rotating mechanism and a telescopic mechanism to block sunlight. Since the skylight sunshade device is installed on the outdoor window, there are sometimes strong winds outdoors, especially during typhoons. Under strong wind conditions, the sunshade device is at risk of structural damage, which may cause the sunshade to deform, be damaged, or fall off. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable building skylight shading device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable skylight shading device includes a skylight body and a mounting frame. The mounting frame is disposed on the outer surface of the skylight body near the outdoor side. Transparent glass is disposed between the inner walls of the skylight body. Multiple sunshade panels are rotatably mounted equidistantly between the inner walls on opposite sides of the mounting frame. The sunshade panels are hollow. Multiple air inlets are evenly distributed on the outer surface of the sunshade panel near the outdoor side. The air inlets are located on the outer surface of the sunshade panel at the middle position. A sliding plate is slidably mounted on the inner wall of the sunshade panel near the air inlets. Multiple through holes are evenly distributed on the outer surface of the sliding plate. Two first limiting pins are fixedly mounted on the inner wall of the sunshade panel near the air inlets. Two first limiting grooves are formed on the outer surface of the sliding plate. The two first limiting pins are slidably mounted with the inner walls of the two first limiting grooves respectively. Multiple exhaust holes are evenly distributed through the top and bottom walls of the sunshade panel. The exhaust ends of the multiple exhaust holes are located above the skylight body.

[0008] As a further embodiment of the present invention, a sliding rod is fixedly installed at one end of the sliding plate, and the end of the sliding rod away from the sliding plate slides through the outer surface of the sunshade and is slidably installed with its inner wall. A plurality of fixing blocks are fixedly installed at equal intervals on the upper surface of the mounting frame near the sliding rod, and the end of the sliding rod away from the sliding plate is rotatably installed with the outer surface of one side of the fixing block.

[0009] As a further embodiment of the present invention, a driving block is fixedly installed at the end of the sunshade away from the sliding rod through the outer surface of the mounting frame, and a sliding plate is slidably installed on the outer surface of the mounting frame near the driving block. Two second limiting grooves are formed on the outer surface of the sliding plate, and two second limiting pins are fixedly installed on the outer surface of one side of the mounting frame. The two second limiting pins are slidably installed with the inner walls of the two second limiting grooves respectively.

[0010] As a further embodiment of the present invention, a drive column is fixedly installed at the bottom end of the drive block, and a plurality of drive grooves are equidistantly opened on the outer surface of the slide plate. The drive column is slidably installed on the inner wall of the drive groove. An electric telescopic rod is fixedly installed on the upper surface of the other side of the mounting frame. The telescopic end of the electric telescopic rod is fixedly connected to the outer surface of the slide plate. The drive groove and the center line of the slide plate are perpendicular to each other.

[0011] As a further embodiment of the present invention, two lead screws are symmetrically and rotatably installed between the inner walls on opposite sides of the mounting frame, and scrapers are slidably installed on the outer surfaces of the two lead screws. The lead screws and scrapers are threadedly connected, and the scrapers are located below the sunshade and abut against the upper surface of the transparent glass.

[0012] As a further embodiment of the present invention, driven gears are fixedly installed on the outer surfaces of the two lead screws near the slide plate, and two transmission gears are rotatably installed on the outer surface of the mounting frame near the driven gears. The two transmission gears mesh with the two driven gears respectively, and drive gears are fixedly installed through the outer surface of the mounting frame at the ends of the two transmission gears near the slide plate.

[0013] As a further embodiment of the present invention, racks are fixedly installed on the upper surfaces of the slide plate near both ends, and the racks mesh with drive gears.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The wind force causes the sun visor to bend, connecting the through holes on the sliding plate with the air inlet. Wind enters the interior of the sun visor through the air inlet and then blows out through the exhaust hole. Since the exhaust end of the exhaust hole faces the transparent glass and the exhaust hole is flared, a reaction force is generated. This reaction force counteracts part of the wind force acting on the sun visor, thus ensuring that the sun visor is not damaged in strong winds, thereby preventing the sun visor from deforming, being damaged, or falling off.

[0016] 2. The driven gear drives the lead screw to rotate, which in turn drives the scraper to slide along the outer surface of the transparent glass to remove the dust. The dust is blown out through the gaps between the sunshades by the external wind. With this device, when the sunshade is first opened, the electric telescopic rod moves back and forth for one stroke, so that the scraper cleans the outer surface of the transparent glass, allowing light to enter.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components.

[0031] Reference Figures 1-10An adjustable skylight shading device includes a skylight body 1 and a mounting frame 2. The mounting frame 2 is disposed on the outer surface of the skylight body 1 near the outside. A transparent glass 25 is disposed between the inner walls of the skylight body 1. Multiple sunshade panels 5 are rotatably mounted at equal intervals between the inner walls on opposite sides of the mounting frame 2. The sunshade panels 5 are hollow. Multiple air inlets 9 are evenly distributed on the outer surface of the sunshade panel 5 near the outside. The air inlets 9 are disposed on the outer surface of the sunshade panel 5 at the middle position. A sliding plate 6 is slidably mounted on the inner wall of the sunshade panel 5 near the air inlets 9. Multiple through holes 13 are evenly distributed on the outer surface of the sliding plate 6. Two first limiting pins 15 are fixedly installed on the wall. Two first limiting grooves 14 are opened on the outer surface of the sliding plate 6. The two first limiting pins 15 are slidably installed with the inner walls of the two first limiting grooves 14 respectively. Multiple exhaust holes 10 are evenly opened through the top and bottom walls of the sunshade 5. The exhaust ends of the multiple exhaust holes 10 are set above the sunroof body 1. A sliding rod 7 is fixedly installed at one end of the sliding plate 6. The end of the sliding rod 7 away from the sliding plate 6 is slidably installed through the outer surface of the sunshade 5 and its inner wall. Multiple fixing blocks 8 are fixedly installed at equal intervals on the upper surface of the mounting frame 2 near the sliding rod 7. The position of the sliding rod 7 is restricted by the fixing blocks 8 to facilitate the movement of the sliding plate 6.

[0032] Due to the force of the wind, the sun visor 5 bends, connecting the through hole 13 on the sliding plate 6 with the air inlet 9. Wind enters the interior of the sun visor 5 through the air inlet 9 and then exits through the exhaust hole 10. Since the exhaust end of the exhaust hole 10 faces the transparent glass 25 and is funnel-shaped, a reaction force is created. This reaction force counteracts some of the wind force acting on the sun visor 5, ensuring that the sun visor 5 is not damaged in strong winds, thus preventing deformation, damage, and detachment. When strong wind enters the hollow part of the sun visor 5 through the air inlet 9, the airflow flows internally and is finally discharged through the funnel-shaped exhaust hole 10. This design allows the wind... The airflow can flow freely within the sun visor 5, reducing the direct impact of wind on its surface. After the wind enters through the air inlet 9, some of the wind force is absorbed and converted within the sun visor 5, reducing the wind pressure directly acting on its surface. Through effective airflow guidance, wind pressure can be balanced to a certain extent, thereby reducing the load on the sun visor 5. The design of the flared exhaust port 10 helps the airflow to exit more smoothly, thereby reducing eddies and aerodynamic drag. This not only reduces the wind force on the sun visor 5 but also improves its overall aerodynamic performance. Due to the presence of internal airflow, it can play a certain buffering role, thereby improving the stability of the sun visor 5 under wind force and reducing the risk of deformation and damage caused by wind pressure.

[0033] In this embodiment, a drive block 11 is fixedly installed on the end of the sunshade 5 away from the slide bar 7, passing through the outer surface of the mounting frame 2. A slide plate 4 is slidably installed on the outer surface of the mounting frame 2 near the drive block 11. Two second limiting grooves 17 are opened on the outer surface of the slide plate 4. Two second limiting pins 18 are fixedly installed on the outer surface of one side of the mounting frame 2. The two second limiting pins 18 are slidably installed with the inner walls of the two second limiting grooves 17 respectively. A drive column 12 is fixedly installed at the bottom end of the drive block 11. Multiple drive grooves 16 are equidistantly opened on the outer surface of the slide plate 4. The drive column 12 is slidably installed with the inner wall of the drive groove 16. An electric telescopic rod 3 is fixedly installed on the upper surface of the other side of the mounting frame 2. The telescopic end of the electric telescopic rod 3 is fixedly connected to the outer surface of the slide plate 4. The drive grooves 16 and the center lines of the slide plate 4 are perpendicular to each other.

[0034] The telescopic movement of the telescopic end of the electric telescopic rod 3 drives the slide plate 4 to move back and forth, which in turn drives the drive groove 16 to move. The drive groove 16 drives the drive block 11 to swing through the drive column 12. The drive block 11 drives the sunshade 5 to rotate within an angle range. The rotation of the sunshade 5 can adjust the gap between two adjacent sunshades 5, thereby adjusting the amount of sunlight penetrating the sunshade 5. This device can adjust the amount of sunlight penetrating the sunshade 5.

[0035] In this embodiment, two lead screws 19 are symmetrically and rotatably mounted between the inner walls of opposite sides of the mounting frame 2. Scraper blades 20 are slidably mounted on the outer surfaces of the two lead screws 19. The lead screws 19 and scraper blades 20 are threadedly connected. The scraper blades 20 are located below the sunshade 5 and abut against the upper surface of the transparent glass 25. Driven gears 24 are fixedly mounted on the outer surfaces of the two lead screws 19 near the end of the slide plate 4. Two transmission gears 23 are rotatably mounted on the outer surface of the mounting frame 2 near the driven gears 24. The two transmission gears 23 mesh with the two driven gears 24 respectively. Drive gears 22 are fixedly mounted through the outer surface of the mounting frame 2 at the end of the two transmission gears 23 near the slide plate 4. Racks 21 are fixedly mounted on the upper surfaces of the slide plate 4 near both ends. The racks 21 mesh with the drive gears 22.

[0036] The slide plate 4 drives the two racks 21 to move, the racks 21 drive the drive gear 22 to rotate, the drive gear 22 drives the transmission gear 23 to rotate, and the transmission gear 23 drives the lead screw 19 to rotate through the driven gear 24. This causes the lead screw 19 to drive the scraper 20 to slide along the outer surface of the transparent glass 25 to scrape away the dust on its outer surface. The scraped dust escapes from the gaps between the sunshades 5 under the blowing of the external wind. With this device, when the sunshade 5 is just opened, the electric telescopic rod 3 can move back and forth for one stroke, so that the scraper 20 can clean the outer surface of the transparent glass 25, making it easier for light to enter.

[0037] It should be noted that, in use, the telescopic movement of the electric telescopic rod 3 drives the sliding plate 4 to reciprocate, causing the sliding plate 4 to move the drive groove 16. The drive groove 16, through the drive column 12, drives the drive block 11 to oscillate. The drive block 11 causes the sunshade 5 to rotate within a certain angle range. The rotation of the sunshade 5 can adjust the gap between two adjacent sunshades 5, thereby adjusting the amount of sunlight penetrating the sunshade 5. This device can adjust the amount of sunlight penetrating the sunshade 5. Simultaneously, the sliding plate 4 drives the two racks 21 to move, the racks 21 drive the drive gear 22 to rotate, the drive gear 22 drives the transmission gear 23 to rotate, and the transmission gear 23, through the driven gear 24, drives the lead screw 19 to rotate. This causes the lead screw 19 to drive the scraper 20 to slide along the outer surface of the transparent glass 25 to scrape away the dust on its outer surface. Driven by external wind, light escapes through the gaps between the sunshade panels 5. This device allows the electric telescopic rod 3 to move back and forth once when the sunshade panel 5 is first opened, causing the scraper 20 to clean the outer surface of the transparent glass 25, facilitating the entry of light. When the sunshade panel 5 encounters strong wind, the wind force causes the sunshade panel 5 to bend, connecting the through hole 13 on the slider 6 with the air inlet 9. The wind enters the interior of the sunshade panel 5 through the air inlet 9 and then blows out from the exhaust hole 10. Since the exhaust end of the exhaust hole 10 faces the transparent glass 25 and the exhaust hole 10 is horn-shaped, a reaction force is formed. This reaction force counteracts part of the wind force acting on the sunshade panel 5, thus ensuring that the sunshade panel 5 is not damaged in strong winds, thereby preventing the sunshade panel 5 from deforming, being damaged, or falling off.
