Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0026] like Figures 1 to 5 As shown, this utility model embodiment discloses a novel louver, including a first support portion 3, an upper blade 1 and a lower blade 2 disposed opposite to each other. The first support portion 3 extends from the inner side of the lower blade 2 to the upper blade 1. One side of the lower blade 2 bends and extends to the upper blade 1 to form a second support portion 4. The upper blade 1 transitions from the top arc of the first support portion 3 to the lower blade 2 to form a first arc-shaped portion 11. The upper blade 1 transitions from the top arc of the first support portion 3 to the top of the second support portion 4 to form a second arc-shaped portion 12. The top of the first support portion 3 is higher than the top of the second support portion 4.

[0027] In this embodiment, the upper blade 1 forms a first arc-shaped part 11 and a second arc-shaped part 12 through a circular arc transition. This can effectively disperse the force, allowing the force of rainwater to be transmitted along the arc to various parts of the blade, rather than being concentrated at a single point. This makes the force of rainwater more evenly distributed on the blade, thereby reducing the possibility of stress concentration and deformation of the blade, improving the strength and stability of the structure, and meeting the installation requirements of large areas.

[0028] Compared to existing louvers, the upper blade 1 of this embodiment has a larger arc transition to distribute the force, and the height of the first support part 3 has been increased to bear a heavier load and meet the needs of a larger area.

[0029] In some embodiments, one side of the second arc-shaped portion 12 extends toward the lower blade 2 to form a guide portion 5, the guide portion 5 having the same radius as the second arc-shaped portion 12, and the guide portion 5 having a connecting groove 51.

[0030] Furthermore, a water collection trough 6 is provided on the other side of the lower blade 2. One side of the water collection trough 6 is connected to the first arc-shaped part 11 in an arc transition, and the other side of the water collection trough 6 is bent to form a connecting part 61.

[0031] The installation method of multiple louvers to form a louver window is to insert one end of the fastener into the connecting groove 51 and fix the other end of the fastener to the connecting part 61 of the water collection tank 6; or, one end of the fastener is pre-assembled on the connecting part 61 of one louver and the other end of the fastener is embedded in the connecting groove 51 of another louver, so as to achieve the connection and fixation of adjacent louvers.

[0032] After the louvers are installed, the guide section 5 formed by the downward extension of the second arc-shaped portion 12 of the louver connects with the water collection groove 6 of the other louver, and the first arc-shaped portion 11 of the louver directly connects with the water collection groove 6. When it rains, some rainwater slides from the second arc-shaped portion 12 of the louver into the water collection groove 6 of the other louver, and some rainwater slides from the first arc-shaped portion 11 of the louver into the water collection groove 6 of the louver, and then flows into other drainage structures to achieve drainage.

[0033] In some embodiments, the arc length of the first arc portion 11 is smaller than the arc length of the second arc portion 12.

[0034] Designing curved sections on the blades of large-span louvers can effectively improve their load-bearing capacity in rainy weather. The curved design can better disperse the concentrated load generated by rainwater, avoid stress concentration in specific areas of the blades, thereby improving the overall stability and resistance to damage of the structure. It also transforms vertical loads into pressure along the curved direction, thereby reducing the bending moment borne by the blades.

[0035] The longer second arc-shaped section 12 can serve as the main structure bearing the primary load, bearing greater loads and withstanding significant wind or rain pressure, while the shorter first arc-shaped section 11 can serve as a detailed structure bearing secondary loads, providing higher stiffness and stability, effectively distributing loads, and improving the overall stability and resistance to damage of the structure.

[0036] Furthermore, the radius of the first arc-shaped portion 11 is smaller than the radius of the second arc-shaped portion 12.

[0037] The second arc-shaped part 12 with a large arc radius is used to bear a larger load, withstand greater wind or rain pressure, provide a better dispersion effect, reduce stress concentration, and thus improve the overall stability of the structure. The first arc-shaped part 11 with a small arc radius bears a smaller load and can provide higher stiffness and local stability.

[0038] The ratio of the arc length of the first arc portion 11 to the arc length of the second arc portion 12 is in the range of 0.6 to 0.9:1, and the ratio of the arc radius of the first arc portion 11 to the arc radius of the second arc portion 12 is in the range of 0.3 to 0.5:1.

[0039] Preferably, the ratio of the arc length of the first arc portion 11 to the arc length of the second arc portion 12 is in the range of 0.8:1, and the ratio of the arc radius of the first arc portion 11 to the arc radius of the second arc portion 12 is in the range of 0.35:1.

[0040] Preferably, the ratio of the arc length of the first arc portion 11 to the arc length of the second arc portion 12 is in the range of 0.8:1, and the ratio of the arc radius of the first arc portion 11 to the arc radius of the second arc portion 12 is in the range of 0.4:1.

[0041] Furthermore, the ratio of the height of the first support part 3 to the height of the second support part 4 is in the range of 1.2 to 1.6:1.

[0042] In some embodiments, a fixing cavity 301 is provided at the upper end of the first support part 3, and the fixing cavity 301 is used to install the rotating structure. Typically, the fixing cavity 301 extends through the end of the louver, and the length direction of the fixing cavity 301 is the same as the length direction of the louver.

[0043] The fixed cavity 301 reduces material costs and allows for the installation of a rotating structure. This rotating structure is further connected to a transmission structure, which is powered by a drive mechanism, enabling the louvers to rotate. This allows for adjustment of the tilt angle of the louver's water collection trough 6 during drainage, facilitating efficient drainage.

[0044] In some implementations, such as Figure 2 As shown, the first support part 3 is provided with a first support ridge 31 and a second support ridge 32 arranged opposite to each other. A partition 33 is provided between the first support ridge 31 and the second support ridge 32. The lower blade 2 is provided with an opening 302 at the position opposite to the partition 33.

[0045] The partition 33 is disposed opposite to the lower blade 2. One end of the first support ridge 31 and one end of the second support ridge 32 are respectively connected to the lower blade 2. The other end of the first support ridge 31 and the other end of the second support ridge 32 are respectively connected to the upper blade. The upper end of the first support ridge 31, the upper end of the second support ridge 32, the upper blade 1 and the partition 33 surround to form the aforementioned fixed cavity 301.

[0046] The lower ends of the first support ridge 31 and the second support ridge 32, the partition 33, and the lower blade 2 can be arranged to form a weight-reducing cavity, reducing the material cost of the blades. Alternatively, an opening 302 can be left at the position of the lower blade 2 relative to the partition 33. In this way, the partition 33, the lower ends of the first support ridge 31 and the second support ridge 32 can form a light source installation space, and the light will radiate from the opening 302, mounting the light source on the partition 33.

[0047] In a specific example, the first arc-shaped portion 11 of the upper blade 1 generally transitions downward from the top of the first support ridge 31 to the lower blade 2, and the second arc-shaped portion 12 transitions downward from the top of the first support ridge 31 to the top of the second support portion 4.

[0048] Of course, the first arc-shaped portion 11 of the upper blade 1 can also be connected to the lower blade 2 by an arc transition from the top of the second support ridge 32, and the second arc-shaped portion 12 can be connected to the top of the second support portion 4 by an arc transition from the second support ridge 32.

[0049] In some embodiments, the first arc-shaped portion 11, the lower blade 2, and the first support portion 3 form a first cavity 7, and the second arc-shaped portion 12, the lower blade 2, and the second support portion 4 form a second cavity 8. The first cavity 7 and the second cavity 8 reduce the weight of the louver, reduce material costs, and facilitate easy installation.

[0050] In some embodiments, the first support portion 3 is provided with fixing grooves 9 at the connection points with the upper blade 1 and the lower blade 2, respectively. The first arc-shaped portion 11 is also provided with fixing grooves 9 at the connection point with the lower blade 2, and the second support portion 4 is also provided with fixing grooves 9 at the connection point with the upper blade 1.

[0051] The fixing groove 9 is used to install the fixing plate of the transmission structure. The fixing plate has a boss that is embedded in the fixing cavity 301. The main body of the transmission structure is connected to the fixing plate. The length direction of the fixing groove 9 is consistent with the length direction of the louver.

[0052] The main function of this utility model is that the upper blades of the louver are enlarged and have a first arc-shaped part and a second arc-shaped part to distribute the force. Compared with the existing louver, the height of the first support part is increased, the overall load-bearing capacity of the louver is increased, and the installation needs of a larger area are met.

[0053] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
