Abstract
Description
Technical Field
[0001] This invention relates to the field of sunshade technology, specifically a low-energy composite external sunshade system. Background Technology
[0002] As is well known, external shading systems are an important component of modern architecture, including permanent, non-adjustable shading components on building facades as well as outdoor shading devices that can be adjusted according to weather and season.
[0003] For example, the invention patent with application publication number CN102433965A, application publication date May 2, 2012, entitled "An Outdoor Rainproof Sunshade System for Building Roofs," includes a frame, a set of blades, a transmission link, and a link shaft; the transmission link is located on the side of the blade, the link shaft is sleeved in the shaft hole at the upper end of the blade, and the blade shaft is installed in the shaft hole at the center end of the blade. A shaped elastic sealing strip is embedded at the lower end of the blade, used to close the gaps between adjacent blades when they are closed. When the outdoor rainproof sunshade is open, large-area natural lighting and ventilation can be achieved by adjusting the angle of the blades; when the outdoor rainproof sunshade is closed, it can provide complete sunshade on sunny days. In summer, during rain or even heavy rainstorms, rainwater can be smoothly discharged along the drainage channels inside the outdoor rainproof sunshade device. The joints between the blades are all inlaid with shaped elastic sealing strips, which can effectively prevent splashing and seepage caused by heavy rain.
[0004] The shortcomings of existing technologies are that outdoor sunshade devices are often installed on the outside of building entrances to help pedestrians avoid wind and rain. However, most of these devices are glass frame structures and louvered sunshade structures. Although glass frame structures can block wind and rain, their sunshade effect is poor. Although louvered sunshade structures can block sunlight better, the grooves on the louvers can easily accumulate rainwater, causing the accumulated rainwater to fall under the sunshade when the louvers are opened and closed. Moreover, the thick louvers can also affect the lighting effect when sunlight is needed. Summary of the Invention
[0005] The purpose of this invention is to provide a low-energy-consumption composite external shading system to overcome the above-mentioned shortcomings of the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-energy composite external sunshade system, comprising an inclined mounting frame, on which louvers are movably arranged in a linear array, and on the side walls of opposite sides of the louvers are respectively provided a first elastic sheet and a second elastic sheet, the louvers being assembled for the following two workstations: In the first station, multiple louvers are located on different planes, and the first elastic sheet and the second elastic sheet are both on the same plane as the corresponding louvers. In the second station, multiple louvers are on the same plane and close together. The middle part of the second elastic sheet is recessed to form a water storage tank, and the end of the first elastic sheet is bent to embed into the water storage tank.
[0007] As a further description of the above technical solution: the second elastic sheet on the same louver is always higher than the first elastic sheet.
[0008] As a further description of the above technical solution: the first elastic sheet and the second elastic sheet are staggered, and the louver is provided with a wedge block located above the second elastic sheet and used to push against the first elastic sheet.
[0009] As a further description of the above technical solution: the side wall of the louver is provided with a groove located below the first elastic sheet and used to push against the end of the second elastic sheet, and the middle part of the second elastic sheet is provided with a groove.
[0010] As a further description of the above technical solution: the two ends of the louver are symmetrically provided with mounting blocks with a "concave" cross-section, and the second elastic sheet is located inside the corresponding mounting block.
[0011] As a further description of the above technical solution: the mounting bracket is provided with a drainage groove inside, and a movable piece extending to the outside is slidably disposed in the drainage groove.
[0012] As a further description of the above technical solution: the inner side of the mounting block is provided with a water inlet trough to guide the movement of water flow, and when the louver is in the second working position, the bottom of the water inlet trough and the top of the movable piece are on the same plane.
[0013] As a further description of the above technical solution: the mounting bracket is internally slidably provided with movable rails located on both sides of the louvers, and the movable rails can be moved to make the spacing between the plurality of louvers adjustable.
[0014] As a further description of the above technical solution: it also includes a movable frame that is slidably installed inside the mounting bracket, and the movable frame moves to make the plurality of louvers rotate synchronously.
[0015] As a further description of the above technical solution: the movable frame is movably installed below the movable rail, and the movable rail moves so that two adjacent louvers always partially overlap in the vertical direction.
[0016] In the above technical solution, the low-energy composite external sunshade system provided by the present invention has the following beneficial effects: On sunny days, multiple louvers rotate synchronously, with the multiple louvers parallel and on different planes. At this time, the louvers are in the first working position, and sunlight can pass through the gaps between the louvers to illuminate the area below the mounting frame, assisting the building's lighting work. At this time, the first and second elastic sheets are both on the same plane with the corresponding louvers, ensuring that the area of sunlight blocked by the louvers is minimized, thereby increasing the space available for sunlight to pass through; On rainy days, multiple louvers rotate to the same plane parallel to the mounting frame and close to the ground. The second elastic sheet is recessed in the middle to form a water storage tank. The mounting frame seals both ends of the water storage tank. The end of the first elastic sheet is bent downward to embed into the water storage tank, sealing the gap between the two louvers. The end of the water storage tank away from the corresponding louver is higher than the side of the corresponding louver. The water storage tank forms a communicating vessel with the first elastic sheet as the dividing surface. The water level that the water storage tank can hold is higher than the corresponding louver. When the water storage tank is full of rainwater, subsequent rainwater cannot enter the water storage tank but can only continue to flow backward along the louvers and then enter the drainage channel on the mounting frame. It is then discharged into the rainwater well through the drainage pipe inside the support column. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0021] Please see Figure 1-13 This invention provides a technical solution: a low-energy composite external sunshade system, including an inclined mounting frame 1, on which louvers 11 arranged in a linear array are movably mounted. A first elastic sheet 111 and a second elastic sheet 112 are respectively disposed on the sidewalls of opposite sides of the louvers 11. The louvers 11 are assembled for the following two workstations: In the first station, multiple louvers 11 are located on different planes, and the first elastic sheet 111 and the second elastic sheet 112 are both on the same plane as the corresponding louvers 11. In the second station, multiple louvers 11 are on the same plane and close together, the middle of the second elastic sheet 112 is recessed to form a water storage tank, and the end of the first elastic sheet 111 is bent to be embedded in the water storage tank. The second elastic sheet 112 on the same louver 11 is always higher than the first elastic sheet 111.
[0022] Specifically, the mounting frame 1 is symmetrically provided with support columns 14, one pair of support columns 14 being located at the bottom of the lower side of the mounting frame 1 and having a drain pipe 141 inside, and the pair of support columns 14 being attached to the main body of the building, and the mounting frame 1 having a drain trough 142 connected to the drain pipe 141 inside.
[0023] Furthermore, on sunny days, multiple louvers 11 rotate synchronously, parallel to each other and on different planes. At this time, the louvers 11 are in their first position, allowing sunlight to pass through the gaps between them and illuminate the area below the mounting frame 1, thus aiding in the building's lighting. Simultaneously, the first elastic sheet 111 and the second elastic sheet 112 are both on the same plane as their corresponding louvers 11, minimizing the area blocked by the louvers 11 and maximizing the space available for sunlight to pass through. On rainy days, the multiple louvers 11 rotate to the same plane parallel to the mounting frame 1 and move closer together. The middle of the second elastic sheet 112 is recessed downwards to form... The water storage tank is sealed at both ends by the mounting bracket 1. The end of the first elastic piece 111 is bent downward to embed into the water storage tank, sealing the gap between the two louvers 11. The end of the water storage tank away from the corresponding louver 11 is higher than the side of the corresponding louver 11. The water storage tank forms a communicating vessel with the first elastic piece 111 as the dividing surface. The water level that the water storage tank can hold is higher than the corresponding louver 11. When the water storage tank is full of rainwater, subsequent rainwater cannot enter the water storage tank but can only continue to flow backward along the louver 11, and then enter the drainage channel 142 on the mounting bracket 1. It is discharged into the rainwater well through the drainage pipe 141 inside the support column 14.
[0024] Furthermore, in the above embodiments, both the first elastic sheet 111 and the second elastic sheet 112 are made of elastic copper alloy.
[0025] In another embodiment of the present invention, the first elastic sheet 111 and the second elastic sheet 112 are staggered, and the louver 11 is provided with a wedge 113 located above the second elastic sheet 112 and used to push against the first elastic sheet 111.
[0026] Specifically, during the process of multiple louvers 11 being on the same plane and approaching each other, the louver 11 in the higher position of two adjacent louvers 11 approaches the other louver 11. The first elastic piece 111 on the higher louver 11 approaches the inclined surface of the wedge 113 on the other louver 11. The end of the first elastic piece 111 is pushed downward by the inclined surface of the wedge 113 and then inserted into the water storage tank formed by the bending of the second elastic piece 112, helping to seal the gap between the two adjacent louvers 11.
[0027] In another embodiment of the present invention, a groove is provided on the side wall of the louver 11, which is located below the first elastic sheet 111 and is used to push against the end of the second elastic sheet 112, and a groove is provided in the middle of the second elastic sheet 112.
[0028] Specifically, the groove in the middle of the second elastic sheet 112 is located on the upper surface of the second elastic sheet 112.
[0029] Furthermore, as multiple louvers 11 are on the same plane and approach each other, the louver 11 in the higher position of two adjacent louvers 11 moves towards the other louver 11. The second elastic piece 112 on the louver 11 in the lower position is directly opposite the bottom of the groove on the side wall of the other louver 11. As they continue to approach each other, the end of the second elastic piece 112 slides along the side wall of the groove, and the second elastic piece 112 bends downward with the groove in its middle as the bending point to form a water storage tank. This, in turn, works with the mounting bracket 1 and the first elastic piece 111 to seal the gap between two adjacent louvers 11.
[0030] In another embodiment of the present invention, mounting blocks 12 with a concave cross-section are symmetrically arranged at both ends of the louver 11, and the second elastic sheet 112 is located inside the corresponding mounting block 12.
[0031] Specifically, the first elastic sheet 111 is located outside the corresponding mounting block 12. The mounting block 12 includes an upper part 121 and a lower part 122. The lower part 122 is fixedly installed below the upper part 121 by a screw. Two pairs of symmetrical fixing rings 114 are provided on the louvers 11. An insert block 123 is provided on the lower part 122 to insert into the fixing ring 114. A rotating shaft 124 extending into the mounting frame 1 is provided on the side wall of the upper part 121. A sliding groove adapted to the rotating shaft 124 is provided on the mounting frame 1.
[0032] Furthermore, during rainy weather, multiple louvers 11 are on the same plane and close together, the second elastic sheet 112 bends to form a water storage tank, and the second elastic sheet 112 is located inside the mounting block 12. The two ends of the water storage tank are sealed by the mounting blocks 12 on both sides of the louvers 11 to ensure the water storage capacity of the water storage tank, thereby sealing the gap between two adjacent louvers 11.
[0033] Furthermore, in the above embodiments, when installing or replacing the louver 11, the upper part 121 and the lower part 122 of the mounting block 12 can be separated simply by tightening or loosening the screw, thereby installing or replacing the louver 11.
[0034] In another embodiment of the present invention, the mounting frame 1 is provided with a drainage groove 142 inside, and a movable piece 143 extending to the outside is slidably disposed in the drainage groove 142. A water inlet groove 127 for guiding water flow is provided on the inner side of the mounting block 12. When the louver 11 is in the second working position, the bottom of the water inlet groove 127 and the top of the movable piece 143 are on the same plane.
[0035] Specifically, a spring is provided between the movable piece 143 and the drainage channel 142. The movable piece 143 is provided with a downwardly extending arc-shaped guide piece 144 on the side wall outside the drainage channel 142. The water channel 127 is opened on the lower part 122 of the mounting block 12.
[0036] Furthermore, during rainy weather, the mounting block 12 and the louvers 11 rotate relative to the mounting frame 1. The mounting block 12 pushes the guide plate 144 below the movable plate 143, and the guide plate 144 drives the movable plate 143 to move into the drainage channel 142 until the multiple louvers 11 are on the same plane and close together. The mounting blocks 12 on both sides of the louvers 11 also close together, and the water channels 127 on the multiple mounting blocks 12 are connected. Rainwater leaking from the gap between the second elastic plate 112 and the mounting block 12 can flow backward along the water channels 127. At this time, the movable piece 143 is pushed by the spring and abuts against the innermost mounting block 12 of the mounting frame 1. The bottom of the water channel 127 and the top of the movable piece 143 are on the same plane. The movable piece 143 can guide the rainwater in the water channel 127 into the drainage channel 142 inside the mounting frame 1. The first elastic piece 111 of the louver 11 corresponding to the mounting block 12 is located above the movable piece 143. The rainwater flowing down from the louver 11 will fall onto the movable piece 143 and be guided by the movable piece 143 to the drainage channel 142.
[0037] In another embodiment of the present invention, the mounting bracket 1 is slidably provided with movable rails 13 located on both sides of the louvers 11, and the movable rails 13 can be moved to make the spacing of the plurality of louvers 11 adjustable.
[0038] Specifically, a rocker arm 131 is rotatably mounted on the pivot 124 of the mounting block 12. The rocker arms 131 on any two adjacent mounting blocks 12 are hinged together. A cylindrical block extending into the interior of the movable rail 13 is provided at the hinge point of one of the rocker arms 131. A sliding groove controlled by the cylindrical block is provided on the movable rail 13. The pivot 124 on the innermost mounting block 12 of the mounting frame 1 is rotatably mounted on the mounting frame 1. A first electric telescopic rod is provided between the movable rail 13 and the mounting frame 1.
[0039] Furthermore, during rainy weather, the first electric telescopic rod pushes the movable rail 13 closer to the rotating shaft 124. The movable rail 13 pushes the rocker arm 131 to rotate through the cylindrical block. The rocker arm 131 drives two adjacent mounting blocks 12 to move away from each other. The cylindrical block on the rocker arm 131 moves along the groove on the movable rail 13 until the distance between the mounting blocks 12 is sufficient for it to rotate. Then the mounting blocks 12 rotate to the same plane parallel to the mounting frame 1. Then the movable rail 13 moves away from the direction of rotation. The rocker arm 131 pulls multiple mounting blocks 12 and louvers 11 closer together. The louvers 11 switch to the second position to block rainwater.
[0040] In another embodiment of the present invention, a movable frame 132 is slidably mounted inside the mounting frame 1, and the movable frame 132 moves to make the plurality of louvers 11 rotate synchronously.
[0041] Specifically, a turntable 125 is provided on the rotating shaft 124, and a cylindrical protrusion 126 is provided on the turntable 125 that fits the gap in the middle of the movable frame 132.
[0042] Furthermore, on sunny days, the movable frame 132 moves upward relative to the mounting frame 1, pushing the protrusion 126 upward. The protrusion 126 drives the rotating shaft 124 of the turntable 125 to move, thereby causing the mounting block 12 and the louvers 11 to rotate relative to the mounting frame 1, so that the louvers 11 open and sunlight can pass through the gaps between the louvers 11. On rainy days, the movable block moves downward relative to the mounting frame 1, pushing the mounting block 12 and the louvers 11 to rotate in opposite directions, so that multiple louvers 11 are on the same plane parallel to the mounting frame 1, thereby facilitating the louvers 11 to close together and block rainwater.
[0043] In another embodiment of the present invention, the movable frame 132 is movably mounted below the movable rail 13, and the movable rail 13 moves so that two adjacent louvers 11 always partially overlap in the vertical direction.
[0044] Specifically, a self-springing telescopic rod is provided between the movable rail 13 and the movable frame 132 (this is prior art and will not be described in detail). The mounting frame 1 has a sliding groove inside to guide the movement of the movable frame 132. The mounting frame 1 also has a second electric telescopic rod inside to push the movable frame 132 to move upward.
[0045] Furthermore, on sunny days, the first electric telescopic rod pushes the movable rail 13 to move. The movable rail 13 drives the louvers 11 to move closer or further away via the rocker arm 131. The movable frame 132 drives the louvers 11 to rotate, so that there is always a partial overlap between two adjacent louvers 11 in the vertical direction. This allows oblique sunlight (such as sunlight with a small angle in winter, which helps people under the louvers 11 to keep warm) to block direct sunlight from directly above (such as sunlight with a large angle in summer, which helps people under the louvers 11 to get shade). The movable piece 143 extends outward from the drainage groove 142 under the push of the spring and overlaps with the innermost louver 11 in the vertical direction, thereby blocking the direct sunlight from directly above in the gap between the innermost louver 11 and the mounting bracket 1.
[0046] Furthermore, during rainy weather, the first electric telescopic rod pushes the movable rail 13 closer to the rotating shaft 124. The movable rail 13, through the cylindrical block, pushes the rocker arm 131 to rotate. The rocker arm 131 causes the two adjacent mounting blocks 12 to move away from each other. The cylindrical block on the rocker arm 131 moves along the slide groove on the movable rail 13, and the movable rail 13, through the self-springing telescopic rod, pushes the movable frame 132 downward. The movable frame 132 pushes the mounting blocks 12 and the louvers 11 to rotate until the two adjacent mounting blocks 12 overlap, the mounting blocks 12 stop rotating, the movable rail 13 continues to move, and the self-springing telescopic rod is compressed until it pushes the first elastic plate 111 and the second elastic plate 112 on the adjacent louvers 11 to misalign. At this time, the self-springing telescopic rod releases some of the accumulated elastic potential energy, extends and pushes the mounting blocks 12 and the louvers 11 to rotate, and the movable frame 132 moves to the lowest point of the slide groove. The louvers 11 are on the same plane parallel to the mounting bracket 1. Then the movable rail 13 moves away from the direction of rotation. The self-springing telescopic rod continues to extend to release the accumulated elastic potential energy. The movable rail 13 pulls multiple mounting blocks 12 and louvers 11 together through the rocker arm 131. The louvers 11 switch to the second position to block rainwater. After the rain, the movable rail 13 moves down to separate the louvers 11. At this time, the second electric telescopic rod pushes the movable frame 132 to move upward. The movable frame 132 drives the mounting blocks 12 and louvers 11 to rotate through the turntable 125, so that the adjacent mounting blocks 12 are staggered. Then the movable rail 13 moves upward, driving the inclined louvers 11 to move together. The movable rail 13 drives the movable frame 132 to move through the self-springing telescopic rod, so that the two adjacent louvers 11 always have a partial overlap in the vertical direction to block the direct sunlight from directly above.
[0047] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
