Description

Technical Field

[0001] This utility model belongs to the field of sunshade louver technology, and specifically relates to a sunshade louver. Background Technology

[0002] In modern architecture, glass curtain walls are increasingly used for walls or roofs. Glass has excellent light transmittance, allowing sunlight to enter and making interior spaces brighter. When there is ample natural light, indoor lighting can be reduced, leading to energy conservation and emission reduction. However, the high light transmittance of glass curtain walls also comes with significant drawbacks: in summer, strong sunlight can cause a rapid increase in indoor temperature due to the large amount of direct sunlight entering the room; and the strong light can affect the visual comfort of occupants. To address these issues, louvers are widely used as an important architectural shading component. Louvers control the amount and angle of light by adjusting their rotation angle, allowing for customized lighting according to individual needs.

[0003] Patent CN201821479040.9 discloses an outdoor sunshade louver. The device includes a frame, an electric telescopic rod, a battery, blades, and a control button. The frame is a closed rectangular structure formed by splicing a top plate, side plates, and a bottom plate. Blades are movably installed on the inner side of the side plates via fixing grooves. Connecting rods are fixed on both sides of the blades, and one side of the blades is connected to the electric telescopic rod via a connecting rod. A light-emitting device and a baffle are also provided on the front of the side plates. Its working principle is as follows: the electric telescopic rod is extended and retracted by the control button. The electric telescopic rod drives the connecting rod of the blades to move, thereby driving the blades to rotate around the axis of the connecting rod, achieving blade angle adjustment.

[0004] The aforementioned patent has the following technical problems: 1. Sufficient space needs to be reserved on one side of the blade to accommodate the overall structure and movement trajectory of the electric telescopic rod, resulting in an increase in the overall thickness of the sunshade louver. 2. When adjusting the blade angle, the electric telescopic rod needs to push the connecting rod up and down while also moving away from or towards the blade rotation axis; this often results in low blade angle adjustment accuracy, or problems such as the rotation angle not matching expectations, or adjustment jamming.

[0029] See Figures 1-7 This is one embodiment of a sunshade louver proposed in this utility model. The sunshade louver includes: a frame 10 and blades 20, with the blades 20 rotatably disposed between two frame 10s. Multiple blades 20 between the two frame 10s are defined as a blade group. The blade group is equipped with a drive motor 31 and a first connecting rod 32 for realizing the linkage of the multiple blades 20. The first connecting rod 32 is hinged to the multiple blades 20. The blade connected to the drive motor 31 is the active blade 29, and the drive motor 31 directly drives the rotation of the active blade. The other blades are driven blades.

[0030] In this embodiment, the drive motor 31 directly drives the active blade 29 to rotate, significantly reducing installation space and improving scenario adaptability. The drive motor 31 directly drives the active blade 29 to rotate through the output shaft, and the motion is a single rotation drive, which makes the force relationship simpler and more stable, which is beneficial to improving adjustment accuracy and component life. The active blade 29 is hinged to multiple blades 20 through the first connecting rod 32. When the active blade 29 rotates, it can synchronously drive the other blades 20 to rotate through the first connecting rod 32, so as to achieve uniform angle adjustment of all blades 20. The hinged linkage structure is simple and has a low failure rate, which can further reduce the overall complexity and cost of the device, while improving the stability of the adjustment process.

[0031] In some embodiments of this application, a blade group may be equipped with one drive motor 31, or two or more synchronous motors that rotate synchronously. Depending on the number of blades, blade size, power of the drive motor 31, etc., one blade group or multiple blade groups may be set between the two frame edges 10.

[0032] In some embodiments of this application, the output shaft of the drive motor 31 serves as the rotation shaft of the active blade 29. The rotation of the active blade 29 is achieved by rotating the output shaft. To enable the drive motor 31 to drive the rotation of the active blade 29, the drive motor 31 is fixed on the active blade 29, and the output shaft is mounted on the frame 10. When the rotation shaft rotates, the drive motor 31 drives the active blade 29 to rotate. The rotation of the active blade 29 drives the driven blade to rotate together through the first connecting rod 32.

[0033] In some other embodiments of this application, the drive motor 31 may be fixed on the frame 10 and the output shaft may be mounted on the active blade 29.

[0034] In some embodiments of this application, a first connecting plate 21 is provided on the blade 20, and a connecting shaft 33 is provided between the first connecting plate 21 and the first connecting rod 32. The first connecting plate 21 and the first connecting rod 32 are hinged together. The first connecting plate 21 and the first connecting rod 32 are arranged parallel to each other, and the first connecting rod 32 is arranged parallel to the frame 10. The first connecting rod 32 is arranged vertically, and multiple blades 20 in the blade group are all hinged to the first connecting rod 32. The first connecting plate 21 and the first connecting rod 32 are arranged parallel to each other and are hinged together by the connecting shaft 33. The first connecting rod 32 can synchronously convert the rotation of the active blade 29 into a thrust or pull force on all blades, ensuring that the rotation angle of all blades 20 is completely consistent and avoiding the deviation of the force transmission direction. The first connecting plate 21 and the first connecting rod 32 are arranged parallel to each other, and the first connecting rod 32 is arranged vertically. The entire linkage structure can fit tightly against the inner side of the frame 10 without occupying additional horizontal space, further reducing the overall thickness of the sunshade louver.

[0035] In some embodiments of this application, the connecting shaft 33 has a shaft body 331, a stop cap 332 extending radially along one end of the shaft body 331, and an extension body 333 extending axially along the other end of the shaft body 331. The radial dimension of the shaft body 331 is larger than the radial dimension of the extension body 333. The shaft body 331 and the extension body 333 form a radial dimension difference, constituting a stepped structure. During assembly, the smaller extension body 333 can be passed through the fixing hole 211 of the first connecting plate 21 first, and then the larger shaft body 331 can achieve automatic positioning without additional measurement and positioning. The stop cap 331 extends radially along one end of the shaft body 331 and can directly abut against the outer side of the first connecting plate 32 after assembly, preventing axial movement of the connecting shaft 33 and eliminating the need for additional installation of nuts, snap rings, and other fasteners, thus simplifying the installation process.

[0036] In some embodiments of this application, a hinge hole 321 is provided on the first connecting rod 32 for the shaft 331 to pass through, and a fixing hole 211 is provided on the first connecting plate 21 to match the extension body 333. The shaft body 331 is rotatably located in the hinge hole 321 within the fixing hole 211 where the extension body 333 is fixed.

[0037] In some embodiments of this application, the blade assembly further includes a second connecting rod 34 hinged to multiple blades 20. The second connecting rod 34 is parallel to the first connecting rod 32, and the first connecting rod 32 and the second connecting rod 34 are located on the inner and outer sides of the rotation axis 25 of the blade 20, respectively, forming symmetrical force transmission points. When the active blade 29 drives the connecting rod to move, the two connecting rods simultaneously apply thrust or pull from both sides of the blade 29, avoiding the blade 20 from generating additional torsion around the rotation axis 25 due to unilateral force application by a single connecting rod. The parallel arrangement of the two connecting rods can strictly limit the movement trajectory of the blades 20, ensuring that each blade 20 can only rotate around its own rotation axis, and guaranteeing that the adjustment angles of all blades are completely synchronized.

[0038] In some embodiments of this application, a rotating shaft 25 is provided at the center of the blade 20. A first connecting plate 21 extends upward along one side of the blade 20 and is hinged to the first connecting rod 32. A second connecting plate 22 extends downward along the other side of the blade 20 and is hinged to the second connecting rod 34. The first connecting plate 21 and the second connecting plate 22 are arranged in parallel. The first connecting plate 21 and the second connecting plate 22 are provided at the end of the blade 20. The first connecting plate 21 is arranged upward and the second connecting plate 22 is arranged downward in opposite directions, forming a symmetrical force-bearing structure centered on the rotating shaft. When the connecting rod pushes the connecting plate, the forces on both sides can completely offset the torque of the rotating shaft 25, preventing the blade 20 from bending or deforming due to uneven force on one side.

[0039] In some embodiments of this application, when blades 20 are provided on both the left and right sides of the frame 10, a common rotating shaft 25 is provided between the two blades 20. A through hole is provided on the frame 10 for the rotating shaft 25 to pass through, and the left and right ends of the rotating shaft 25 are respectively fixed on the two blades 20. The two blades share the same rotating shaft, which can reduce the installation space of one rotating shaft and significantly reduce the overall thickness of the blades on both sides.

[0040] In some embodiments of this application, the blade 20 has a blade body 26, a fixing seat 27 disposed at the end of the blade body 26, and an end cap 28 for fixing the fixing seat 27. The rotating shaft 25 is fixed on the fixing seat 27. The fixing seat 27 has a base 271 and a fixing edge 272 extending radially outward along one end of the base 271. An extension opening for the base 271 to extend is provided on the end cap 28. The fixing edge 272 is located on the side of the end cap 28 closer to the blade body 26. A fixing groove for fixing the rotating shaft 25 is provided on the base 271. The fixing edge 272 of the fixing seat 27 extends radially outward along one end of the base 271. The extension opening of the end cap 28 only allows the base 271 to extend. The fixing edge 272 is stuck between the end cap 28 and the blade body 26, forming an axial limit to prevent the fixing seat 27 from moving axially when the blade 20 rotates. The contact area between the fixing edge 272 and the end cap 28 and the blade body 26 can be increased, the force on the fixing seat can be distributed, and the overall connection stability can be improved. The fixing groove opened on the seat 271 can accurately position the rotating shaft 25, avoid the rotating shaft 25 from being offset or tilted during installation, and ensure the coaxiality of the rotating shaft 25 and the blade body 26.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
