Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a shutter structure and a curtain wall. Background Art

[0002] A building curtain wall refers to the non-load-bearing exterior enclosure of a building. It typically consists primarily of panels and a supporting structural system, often using large areas of translucent materials such as glass. While this provides good lighting and a good view, it can also easily lead to excessive indoor sunlight exposure. Therefore, louvers are often installed on the exterior or interior of the curtain wall. By adjusting the angle and spacing of the louvers, the amount of sunlight entering can be effectively controlled, providing shade, preventing indoor overheating, and reducing air conditioning energy consumption. Furthermore, when daylight is needed, the angle of the louvers can be adjusted appropriately to allow an appropriate amount of natural light into the room, achieving controlled daylighting. For example, in the hot summer, the louvers can be closed or tilted at a larger angle to block strong direct sunlight. In winter or on cloudy days, the louvers can be opened to fully utilize natural light and reduce lighting energy consumption.

[0003] Existing louver structures are usually set vertically, and a driving structure is set at the bottom and bottom of the louver structure to synchronously drive the rotation of multiple louver blades. In the existing technology, this driving structure is usually a structure with multiple gear transmissions. However, with the development of the times, there is a demand not only for vertically set louver structures, but also for horizontally set louver structures. In the research and development of horizontally set louver structures, it was found that for louvers with the same horizontal and vertical shapes and sizes, the vertically set louver structure cannot be simply rotated 90° to be used as a horizontally set louver structure. The reason is that the size and force mode have changed. Because the internal driving structure and force mode are different, it is necessary to rearrange and design the connection method and driving structure, otherwise it is easy to cause interference or even the problem of being unable to rotate.

[0004] Therefore, it is urgent to design a new horizontally arranged louver structure, rather than simply rotating the vertically arranged louver structure by 90 degrees to use it as a horizontal louver. Utility Model Content

[0026] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] An embodiment of the present invention discloses a louver structure. The louver structure is a building decoration and sunshade component, which is usually composed of a series of parallel louvers. The angles of these louvers can be adjusted to control the entry of light and block sight.

[0030] The following can be combined with the attached Figure 1-Figure 5 Describe the louver structure of the present application.

[0031] In a specific embodiment, the louver structure includes a fixed frame 1, a connecting rod 2 and a plurality of spaced-apart transverse louvers 3, one end of each transverse louver 3 is passed through the fixed frame 1 and extends into the fixed frame 1, and the end is set as the inner end of the frame; the inner end of one of the transverse louvers 3 is provided with a gear 4 and the gear 4 is engaged with a worm 5, one end of the worm 5 is passed through the fixed frame 1 and extends to the outside of the fixed frame 1, and the inner ends of the remaining transverse louvers 3 are fixed with swing arms 31; the gear 4 and the plurality of swing arms 31 are rotatably set on the same connecting rod 2 through their respective rotating shafts, and the connecting rod 2 is set in the fixed frame 1.

[0032] The present application is a specially designed new horizontally arranged louver structure, and its internal drive structure is also adaptively designed for the horizontally arranged louver structure. That is, the louver structure of the present application is specially provided with multiple horizontal louvers 3. The drive structure of the multiple horizontal louvers 3 is specifically implemented by the cooperation of the connecting rod 2, the gear 4 and the worm 5. The specific driving principle is as follows:

[0033] One of the multiple transverse louvers 3 is specifically provided with a gear 4 and a worm 5 is meshed with the gear 4, while the remaining transverse louvers 3 are specifically provided with swing arms 31. The gear 4 and the swing arms 31 are connected to the same connecting rod 2. Therefore, when the worm 5 is driven to rotate, the gear 4 will also rotate, and at the same time drive the connecting rod 2 to rotate, and then the connecting rod 2 drives the swing arms 31 to rotate, thereby achieving the synchronous rotation of the multiple transverse louvers 3. In addition, the cooperation between the worm 5 and the gear 4 also has a certain self-locking function, that is, when the multiple transverse louvers 3 are adjusted to a suitable placement angle, the multiple transverse louvers 3 can stably maintain the suitable placement angle without swinging arbitrarily, and can be fixed at any angle.

[0034] It should be noted that the distance between the inner end of the transverse louver 3 on the gear 4 and the rotating shaft is equal to the length of the swing arm 31, which can better achieve synchronous rotation of multiple transverse louvers 3.

[0035] It should also be noted that since the louver structure of the present application is specifically a horizontally arranged louver structure, the driving structure will be specifically located on the horizontal left or right side of the louver structure. Therefore, in order to better protect the driving structure, the relevant driving structure is assembled into the fixed frame 1 for protection, which can improve the overall safety.

[0036] In summary, the present application is a specially designed new horizontally arranged louver structure, rather than simply rotating the vertically arranged louver structure by 90°, which can better meet the user's needs for a horizontally arranged louver structure; at the same time, the louver structure of the present application also has the effect of hovering at any angle, meeting the user's placement needs at different angles; and, the fixed frame 1 can also protect the driving structure very well, which not only extends the service life of the louver structure of the present application, but also makes the appearance beautiful and neat.

[0037] In a specific embodiment, the transverse louver 3 having the gear 4 is used as the driving louver, and the driving louver is arranged in the middle of the plurality of transverse louvers 3. In this arrangement, the gear 4 and the worm 5 are correspondingly arranged in the middle of the entire louver structure, making it easier for the user to operate the worm 5, reducing the difficulty of operation and improving the convenience of operation.

[0038] In a specific embodiment, the worm 5 is engaged with the bottom of the gear 4. In this arrangement, since the driving louvers can be specifically arranged in the middle of the plurality of transverse louvers 3 in the above embodiment, the worm 5 is arranged at the bottom of the gear 4, which makes the worm 5 located in a position slightly below the middle, which is more in line with the operating habits of most users and can effectively improve the operating comfort.

[0039] In one specific embodiment, each transverse louver 3 is sleeved with a louver support block 32 at its inner end. The louver support block 32 is fixed to the inner wall of the fixed frame 1, and a first bearing 33 is disposed between each transverse louver 3 and the louver support block 32. This arrangement effectively supports the transverse louver 3 within the fixed frame 1, thereby improving structural stability. Furthermore, the first bearing 33 improves the smooth rotation of the transverse louver 3, preventing any stalling during rotation.

[0040] In one specific embodiment, one end of the worm 5 is sleeved with a rod support block 51, which is fixed to the inner wall of the fixed block. A second bearing 52 is disposed between the worm 5 and the rod support block 51. This arrangement effectively supports the worm 5 within the fixed frame 1 by providing the rod support block 51, thereby improving the stability of the structure. Furthermore, the second bearing 52 improves the smooth rotation of the worm 5 and prevents any stalling during rotation.

[0041] In a specific embodiment, the fixed frame 1 is assembled from two half-frames 11, one end of each transverse louver 3 is passed through one of the half-frames 11 and extends into the fixed frame 1, and one end of the worm 5 is passed through one of the half-frames 11 and extends out of the fixed frame 1. In actual research and development, it was found that since the relevant drive structure in the louver structure of the present application needs to be assembled in the fixed frame 1, in order to facilitate the assembly of the relevant drive structure in the fixed frame 1, the fixed frame 1 adopts a structure assembled from two half-frames 11. When assembly is required, the two half-frames 11 can be separated first to free up sufficient assembly space for assembly; when the relevant drive structures are assembled, the two half-frames 11 are finally assembled together, which can greatly improve the overall assembly efficiency.

[0042] Specifically, each half frame 11 includes a long frame segment 111, a short frame segment 112, and a connecting frame segment 113 fixed between the long frame segment 111 and the short frame segment 112. The long frame segment 111 of one half frame 11 and the short frame segment 112 of the other half frame 11, as well as the short frame segment 112 of one half frame 11 and the long frame segment 111 of the other half frame 11, are fixed by fasteners. This arrangement has a simple structure, is easy to manufacture, and reduces manufacturing difficulty; at the same time, it also has sufficient structural strength.

[0043] Specifically, the fastener may be a fixed matching structure of a bolt and a nut, or the fastener may be a screw.

[0044] Specifically, the length d1 of the long frame segment 111 of the half frame 11 is within the range of 80 mm ≤ d1 ≤ 84 mm. For example, the length d1 of the long frame segment 111 of the half frame 11 can be 80 mm, 81 mm, 82 mm, 83 mm, or 84 mm. For another example, the length d1 of the long frame segment 111 of the half frame 11 can be another value within the range of 80 mm ≤ d1 ≤ 84 mm. This arrangement not only effectively controls the overall dimensions, but also provides sufficient space for assembling the drive structure.

[0045] Specifically, the length d1 of the long frame section 111 of the half frame 11 is preferably 82 mm.

[0046] Specifically, the length d2 of the connecting frame section 113 of the half frame 11 is within the range of 36 mm ≤ d2 ≤ 40 mm. For example, the length d2 of the connecting frame section 113 of the half frame 11 can be 36 mm, 37 mm, 38 mm, 39 mm, or 40 mm. For another example, the length d2 of the connecting frame section 113 of the half frame 11 can be another value within the range of 36 mm ≤ d2 ≤ 40 mm. This arrangement not only effectively controls the overall dimensions, but also provides sufficient space for assembling the drive structure.

[0047] Specifically, the length d2 of the connecting frame section 113 of the half frame 11 is preferably 38 mm.

[0048] The embodiment of the present invention discloses a curtain wall including the above-mentioned louver structure. The curtain wall refers to a building exterior protective structure or decorative structure composed of a supporting structure system and a louver structure, which has a certain displacement capability relative to the main structure and does not share the load and function of the main structure.

[0049] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
