Description

Technical Field

[0001] This utility model belongs to the field of venetian blind technology, specifically relating to a venetian blind that automatically adjusts light. Background Technology

[0002] With the development of smart homes and automation technologies, Venetian blinds are window coverings that control indoor light and privacy through adjustable horizontal or vertical slats. Venetian blinds typically consist of multiple parallel vertical slats, whose angles can be adjusted to control the amount and direction of light entering the room. Venetian blinds are widely used in residences, office buildings, and other environments requiring controlled light and privacy.

[0003] Venetian blinds control the amount of light entering by adjusting the angle of the vertical slats. Users can manually or electrically adjust the angle of the vertical slats to change the angle of the slats and control the amount of light reflected, refracted, and directly entering the room. By adjusting the angle of the vertical slats, ventilation and lighting can be maintained while blocking outside views. Venetian blinds can effectively block excessive solar radiation heat, maintain indoor temperature, reduce the frequency of air conditioning use, and thus save energy.

[0004] In some existing technologies, there are designs that adjust the angle of light by using venetian blinds. For example, some venetian blind designs control the opening and closing angle of the blinds through electric actuators or transmission mechanisms, thereby adjusting indoor lighting. However, these designs still have some problems, such as the adjustment range being too limited, or the adjustment effect being unsatisfactory when the light changes drastically, especially under strong sunlight, making it difficult to achieve precise control of indoor light. To address these issues, we have designed an automatic light-adjusting venetian blind to provide an alternative technical solution. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-6 An automatic light-adjusting venetian blind includes a rectangular window frame 1, with multiple rotatable longitudinal blades 3 inside the rectangular window frame 1. A rotatable bottom light-reflecting plate 4 is provided at one end of the bottom of the longitudinal blades 3, and a bottom reflector 5 is provided at the other end of the bottom of the longitudinal blades 3. A rotating mechanism for rotating the bottom light-reflecting plate 4 is provided inside the rectangular window frame 1.

[0023] A rectangular mounting box 2 is fixed to the top of the rectangular window frame 1. A first drive motor 8 is fixed inside the rectangular mounting box 2 with bolts. A first longitudinal rotating shaft 6 is fixed to one side of the longitudinal blade 3. The output end of the first drive motor 8 is connected to the first longitudinal rotating shaft 6 through a track. The operation of the first drive motor 8 enables the output end of the first drive motor 8 to rotate. The track enables the longitudinal blade 3 to rotate, thereby enabling the longitudinal blade 3 to rotate around the first longitudinal rotating shaft 6 as the center.

[0024] The first longitudinal rotation axis 6 passes through the interior of the rectangular window frame 1 and is rotatably connected to the rectangular window frame 1 through a bearing, thereby enabling the first longitudinal rotation axis 6 to rotate inside the rectangular window frame 1. The rotation of the first longitudinal rotation axis 6 enables the longitudinal blade 3 to rotate.

[0025] The rotating mechanism includes a transverse rotating column 9, a second drive motor 10 is fixed inside the transverse rotating column 9 by bolts, a transverse threaded rod 11 is fixed at the output end of the second drive motor 10, a transverse sliding block 12 is threaded to the outer side of the transverse threaded rod 11, an oblique transmission rod 13 is rotatably connected to the top of the transverse sliding block 12, an oblique rotating rod 14 is rotatably connected to one end of the oblique transmission rod 13, a second longitudinal rotating shaft 7 is fixed inside the bottom end of the oblique rotating rod 14, and the second longitudinal rotating shaft 7 is fixed to the side of the bottom light refraction plate 4 and fixedly connected to the bottom light refraction plate 4.

[0026] The transverse rotating column 9 is sleeved on the outside of the first longitudinal rotating shaft 6 and fixedly connected to the first longitudinal rotating shaft 6, thereby fixing the transverse rotating column 9. Through the fixing of the transverse rotating column 9 to the first longitudinal rotating shaft 6, the rotation of the first longitudinal rotating shaft 6 can drive the transverse rotating column 9 to rotate.

[0027] Here, the operation of the second drive motor 10 causes the transverse threaded rod 11 to rotate. The rotation of the transverse threaded rod 11 causes the transverse sliding block 12 to move laterally inside the transverse rotating column 9. The lateral movement of the transverse sliding block 12 causes the oblique transmission rod 13 to move. The movement of the oblique transmission rod 13 causes the oblique rotating rod 14 to rotate. This causes the oblique rotating rod 14 to rotate inside the second longitudinal rotating shaft 7. This causes the second longitudinal rotating shaft 7 to drive the bottom light refraction plate 4 to rotate. This allows sunlight from the outside to be refracted through the bottom light refraction plate 4 and the bottom reflector 5. The rotation of the longitudinal blade 3 and the bottom light refraction plate 4 allows the angle of the light to be adjusted.

[0028] The interior of the transverse rotating column 9 is provided with a transverse sliding groove. The transverse sliding block 12 is located inside the transverse sliding groove and is slidably connected to the transverse rotating column 9 through the transverse sliding groove. The transverse sliding groove allows the transverse sliding block 12 to slide laterally inside the transverse rotating column 9, and the transverse sliding groove can guide the movement trajectory of the transverse sliding block 12.

[0029] The rectangular window frame 1 has an arc-shaped sliding groove inside. The second longitudinal rotating shaft 7 is located inside the arc-shaped sliding groove and is movably connected to the rectangular window frame 1 through the arc-shaped sliding groove, so that when the horizontal rotating column 9 rotates, the second longitudinal rotating shaft 7 can move inside the rectangular window frame 1.

[0030] By setting rotatable longitudinal blades 3 and bottom light refraction plates 4, the light entering the room can be precisely adjusted according to different light intensities and angles. The rotation of the bottom light refraction plate 4 and the cooperation of the bottom reflector 5 enable the light to be refracted and reflected more flexibly, thereby effectively adjusting the indoor lighting, preventing strong sunlight from directly entering the room, and improving the indoor lighting environment.

[0031] Working principle: The operation of the second drive motor 10 enables the transverse threaded rod 11 to rotate. The rotation of the transverse threaded rod 11 enables the transverse sliding block 12 to move laterally inside the transverse rotating column 9. The lateral movement of the transverse sliding block 12 enables the oblique transmission rod 13 to move. The movement of the oblique transmission rod 13 enables the oblique rotating rod 14 to rotate, which in turn enables the oblique rotating rod 14 to rotate inside the second longitudinal rotating shaft 7. This, in turn, enables the second longitudinal rotating shaft 7 to drive the bottom light refraction plate 4 to rotate, allowing sunlight to be refracted through the bottom light refraction plate 4 and the bottom reflector 5. The angle of the light can be adjusted by the rotation of the longitudinal blade 3 and the bottom light refraction plate 4.

[0032] Furthermore, by setting rotatable longitudinal blades 3 and bottom light refraction plates 4, the light entering the room can be precisely adjusted according to different light intensities and angles. The rotation of the bottom light refraction plate 4 and the cooperation of the bottom reflector 5 enable the light to be refracted and reflected more flexibly, thereby effectively adjusting the indoor lighting, preventing strong sunlight from directly entering the room, and improving the indoor lighting environment.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
