Abstract
Description
Technical Field
[0001] This utility model relates to an electric folding louver, belonging to the field of building door and window technology. Background Technology
[0002] Venetian blinds are generally used for building exterior windows. In summer, when temperatures rise, they can block sunlight from entering the room, thus preventing the indoor temperature from rising. In winter, by adjusting the angle of the venetian blinds, sunlight can enter the room and raise the indoor temperature. Therefore, they can help buildings save energy and reduce consumption.
[0003] Venetian blinds can be installed indoors or outdoors. Outdoor blinds block sunlight from entering the glass, providing better shading. Currently, outdoor blinds are generally operated manually, with the angle of the inner slats adjusted to control the amount of light blocking. However, since the slats are always in contact with the glass, this can obstruct the view.
[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0005] This utility model addresses the shortcomings of the prior art by providing an electrically folding venetian blind. The blind can be electrically controlled to fold to one side of the window, solving the problem of traditional venetian blinds blocking the view. Furthermore, the rotation angle of the venetian blinds can be electrically adjusted to achieve precise adjustment of the amount and direction of light.
[0006] To solve the above technical problems, the present invention adopts the following technical solution:
[0007] An electrically operated folding louver includes a fixed louver and a sliding louver arranged symmetrically on both sides, which are installed on the outside of an outer frame. The outer frame includes two outer horizontal frames arranged symmetrically on the top and bottom and two outer vertical frames arranged symmetrically on the left and right. An electric push rod A is installed between the fixed louver and the upper outer horizontal frame. Both the fixed louver and the sliding louver include louver blades, louver horizontal frames, and louver vertical frames. The two ends of the louver blades are rotatably installed on the louver vertical frames along the length direction. An electric push rod B and multiple gear assemblies are provided in the louver vertical frame on one side of the louver blades. The electric push rod B controls the direction of the louver blades through the gear assemblies.
[0008] Furthermore, pulley tracks are provided on the opposing inner sides of both outer horizontal frames.
[0009] Furthermore, the fixed louver and the sliding louver are connected by hinge B. The side of the fixed louver away from the sliding louver is connected to the outer vertical frame by hinge A, and the side of the sliding louver away from the fixed louver is connected to the pulley track by a pulley hinge.
[0010] Furthermore, both ends of the electric push rod A are hinged.
[0011] Furthermore, the gear assemblies are configured to correspond one-to-one with the louvers.
[0012] Furthermore, the gear assembly includes meshing gears and racks.
[0013] Furthermore, the racks of adjacent gear assemblies are connected end-to-end in the vertical direction, allowing them to move synchronously.
[0014] Furthermore, the rack is provided with a square hole, and the head of the electric push rod B is connected to the square hole of the rack through a connecting rod.
[0015] Furthermore, the gear is connected to the end of the louver blade, and the gear and the louver blade rotate synchronously.
[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:
[0017] The two window sashes adopt a linked folding design. The electric push rod can fold the two window sashes to the side of the window as a whole, completely freeing up the window space, leaving no obstruction, increasing the amount of light entering, and solving the problem that traditional blinds cannot be fully retracted or block the view.
[0018] The electric push rod drives the rack and pinion to rotate the gear, controlling the direction of the louvers and achieving precise adjustment of the amount and direction of light to meet the shading or lighting needs of different scenarios.
[0019] By replacing manual operation with electric operation, it improves convenience and features a simple structure, is not easily damaged, and is easy to maintain.
[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation
[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0028] like Figures 1-5 As shown in the figure, this utility model provides an electric folding louver, including a fixed louver 2 and a sliding louver 3 arranged symmetrically on the left and right sides, with the fixed louver 2 and the sliding louver 3 installed on the outside of the outer frame 1.
[0029] The outer frame 1 includes two outer horizontal frames 11 arranged symmetrically at the top and bottom and two outer vertical frames 12 arranged symmetrically at the left and right. The inner sides of the two outer horizontal frames 11 are provided with pulley tracks 13.
[0030] The fixed louver 2 and the sliding louver 3 are connected by hinge B5. The side of the fixed louver 2 away from the sliding louver 3 is connected to the outer vertical frame 12 by hinge A4. The side of the sliding louver 3 away from the fixed louver 2 is connected to the pulley track 13 by pulley hinge 6.
[0031] An electric push rod A7 is installed between the fixed louver fan 2 and the upper outer horizontal frame 11. Both ends of the electric push rod A7 are hinged.
[0032] When the electric push rod A7 is working, it drives the fixed louver 2 to move along the axis of hinge A4. While the fixed louver 2 is moving, it drives one side of the sliding louver 3 to move along the axis of hinge B5, and the other side moves along the pulley track 13 under the drive of pulley hinge 6, so that the two louvers can be folded and closed.
[0033] Both the fixed louver 2 and the sliding louver 3 include louver blades 23, louver horizontal frames 21 and louver vertical frames 22. The two ends of the louver blades 23 are rotatably mounted on the louver vertical frames 22 along the length direction.
[0034] The louver frame 22 on one side of the louver blade 23 is equipped with an electric push rod B27 and multiple gear assemblies. The gear assemblies are arranged one-to-one with the louver blade 23. The electric push rod B27 controls the rotation of the louver blade 23 by cooperating with the gear assemblies.
[0035] The gear assembly includes a meshing gear 24 and a rack 25. The racks 25 of adjacent gear assemblies are connected end-to-end in the vertical direction and can move synchronously. The rack 25 is provided with a square hole 26, and the head of the electric push rod B27 is connected to the square hole 26 of the rack 25 through a connecting rod 28. The gear 24 is connected to the end of the louver blade 23, and the gear 24 and the louver blade 23 rotate synchronously.
[0036] When the electric actuator B27 is working, it drives the rack 25 to slide through the connecting rod 28. The rack 25 drives the gear 24 to rotate, and the gear 24 drives the louver 23 to rotate. By setting the stroke of the electric actuator B27, the rotation angle of the louver 23 can be effectively controlled.
[0037] This invention can achieve sun shading of exterior windows. The direction of the louvers 23 can be adjusted by the electric push rod B2, thereby adjusting the amount of light and the direction of light.
[0038] This invention allows the fixed louver 2 and the sliding louver 3 to be folded to one side of the window, making the window unobstructed, increasing the amount of light entering, and making the view more open.
[0039] This invention enables external sunshade for widened windows, and features a simple structure, resistance to damage, and easy maintenance.
