[0037] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] It should be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] It should be noted that in the description of this utility model, the terms "connection" and "installation" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; direct connection or connection through an intermediate medium; mechanical connection or electrical connection. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0040] Among existing blinds, whether manual blinds, electric blinds, or photovoltaic blinds, none of them can achieve autonomous adjustment of the blade angle.

[0041] Based on this, the embodiment of the present utility model provides a photovoltaic tracking smart blinds, referring to Figure 1 The photovoltaic tracking smart blinds include a mounting shell 1, a plurality of blades 2, an angle adjustment chain 3 and an angle adjustment mechanism 4, wherein:

[0042] Angle adjustment chain 3 is connected to each blade 2;

[0043] Each blade 2 includes a base plate 21 and a solar cell panel 22 laid on the base plate 21. A wire for connecting the solar cell panels 22 is wound around the angle adjustment chain 3, and the wire is electrically connected to the angle adjustment mechanism 4.

[0044] The angle adjustment mechanism 4 is mounted on the mounting housing 1 and its power output end is connected to the angle adjustment chain 3 . The angle adjustment mechanism 4 is configured to be able to adjust the angle of the blade 2 according to changes in light intensity.

[0045] To install the photovoltaic tracking smart blinds provided in this application, simply secure the mounting housing 1 to the top of the window. Once installed, several blades 2 are sequentially connected to the angle adjustment chain 3 from top to bottom, with the blades 2 positioned opposite the window. The top end of the angle adjustment chain 3 penetrates the mounting housing 1 and connects to the angle adjustment mechanism 4.

[0046] During operation, the solar panel 22 converts solar energy into electricity and supplies power to the angle adjustment mechanism 4, achieving energy conservation and environmental protection. Furthermore, the angle adjustment mechanism 4 can adjust the angle of the blades 2 according to changes in light intensity. Specifically, when the light intensity is high, the angle adjustment mechanism 4 drives the blades 2 to rotate to increase the spread area of ​​the blind. At this time, the blind blocks a larger area of ​​the window and the solar panel 22 faces the light, thereby preventing excessive light from entering the room and improving the conversion rate of the solar panel 22. When the light intensity is low, the angle adjustment mechanism 4 drives the blades 2 to rotate to reduce the spread area of ​​the blind. At this time, the blind blocks a smaller area of ​​the window, thereby increasing the amount of light entering the room. As described above, the blind provided by the present application can achieve autonomous blade angle adjustment, improving ease of use and indoor comfort, while also positioning the blades 2 at an optimal angle for collecting light energy.

[0047] Continue to refer to Figure 1 The photovoltaic tracking smart blinds provided in this embodiment also include a display screen 7 and / or a temperature sensor and / or a humidity sensor installed on the mounting shell 1.

[0048] Reference Figure 2 and Figure 3A control module 8 is disposed in the mounting housing 1, and a display screen 7 is connected to the control module 8. A mounting hole for fixing the display screen 7 is provided on the side wall of the mounting housing 1 facing the room. The display screen 7 can display information such as indoor temperature and / or indoor humidity and / or time and date, making it more convenient for users to use.

[0049] Reference Figure 2 and Figure 3 The angle adjustment mechanism 4 includes an angle adjustment motor 41 and a roller 42 connected to the output shaft of the angle adjustment motor 41 , and the roller 42 is connected to the angle adjustment chain 3 .

[0050] Specifically, the angle adjustment motor 41 has two output shafts, each connected to a corresponding roller 42. The two rollers 42 are connected to the two angle adjustment chains 3, with the top of each angle adjustment chain 3 inserted into the mounting housing 1 and fixed to the corresponding roller 42. When the angle adjustment motor 41 drives the rollers 42 to rotate, one side of the angle adjustment chain 3 rises and the other side descends, thereby driving the blades 2 to rotate and adjust the blade angle.

[0051] Furthermore, the angle adjustment mechanism 4 further includes a light sensor 43 for detecting light intensity. The angle adjustment mechanism 4 can adjust the angle of the blade 2 according to the detection result of the light sensor 43 .

[0052] Optionally, the light sensor 43 is mounted on the light-facing side of the mounting housing 1 or on the side of the mounting housing 1 facing the interior. Mounting the light sensor 43 on the light-facing side of the mounting housing 1 facilitates positioning the blades 2 at an optimal angle for collecting light energy. Mounting the light sensor 43 on the side of the mounting housing 1 facing the interior further facilitates adjusting the indoor light.

[0053] Continue to refer to Figure 2 and Figure 3 The photovoltaic tracking smart blinds provided in this embodiment also include a lifting drive mechanism 6, which includes a lifting drive motor 61, a reel 62 and a pull rope 63, wherein: the lifting drive motor 61 and the reel 62 are both installed in the mounting shell 1, and the output shaft of the lifting drive motor 61 is connected to the reel 62; the upper end of the pull rope 63 is wound on the reel 62, and the lower end of the pull rope 63 passes through each blade 2 in sequence.

[0054] Specifically, the lower end of the pull rope 63 passes through the wire holes on each blade 2 in sequence, and the bottom end of the pull rope 63 is tied and fixed. The lifting drive motor 61 is used to drive the reel 62 to rotate, so as to wind the pull rope 63 around the reel 62 or lower the pull rope on the reel 62, thereby retracting or lowering the blade 2.

[0055] Continue to refer to Figure 3The photovoltaic tracking smart blinds provided in this embodiment also include a battery 5 housed within the mounting housing 1. The battery 5 is connected between the angle adjustment mechanism 4 and the wires. Furthermore, the battery 5 is electrically connected to the lift drive mechanism 6, the display screen 7, and the control module 8. The battery 5 is used to store the electrical energy converted by the solar panel 22 and to power various electrical components.

[0056] In existing Venetian blinds, the top of the angle adjustment chain 3 is fixed to the roller 42 via a snap or screw connection. If the actual angle of the blade 2 does not match the preset angle, the mounting housing 1 must be disassembled and the fixed position of the angle adjustment chain 3 and the roller 42 adjusted. This method is not only time-consuming and labor-intensive, but also requires a professional on-site inspection, making it inconvenient.

[0057] Based on the above problems, refer to Figure 4 The angle adjustment mechanism 4 also includes a first pressure roller 44, a second pressure roller 45 and a pressure roller driving member 46 installed on the roller 42. The pressure roller driving member 46 is used to drive the first pressure roller 44 to move in a direction close to or away from the second pressure roller 45. The angle adjustment chain 3 passes between the first pressure roller 44 and the second pressure roller 45.

[0058] Specifically, in this embodiment, there are two second pressure rollers 45, both mounted on the roller 42 via pins. The first pressure roller 44 is located between the two second pressure rollers 45. The angle adjustment mechanism 4 also includes a swing rod 47, one end of which is connected to the first pressure roller 44, and the center of which is hinged to the roller 42. The pressure roller driver 46 is an electric push rod, with its ends hinged to the end of the swing rod 47 away from the first pressure roller 44 and the roller 42, respectively.

[0059] Reference Figure 5 The dotted line in the figure represents the angle adjustment chain 3. When the top of the angle adjustment chain 3 needs to be fixed on the roller 42, the pressure roller driving member 46 is controlled to drive the first pressure roller 44 to move in the direction close to the second pressure roller 45, so that the first pressure roller 44 and the second pressure roller 45 clamp the angle adjustment chain 3.

[0060] Reference Figure 6 When the relative position of the angle adjustment chain 3 and the roller 42 needs to be adjusted, the pressure roller driving member 46 is controlled to drive the first pressure roller 44 to move in a direction away from the second pressure roller 45, so that the first pressure roller 44 and the second pressure roller 45 release the angle adjustment chain 3; then, the user manually pulls the angle adjustment chain 3 until the blade 2 is placed to the preset angle; finally, the pressure roller driving member 46 is controlled to drive the first pressure roller 44 to move in a direction close to the second pressure roller 45, so that the first pressure roller 44 and the second pressure roller 45 clamp the angle adjustment chain 3 again.

[0061] Optionally, anti-slip grooves are pressed on the circumferential surface of the first pressing roller 44 to enhance the clamping force of the angle adjustment chain 3 .

[0062] Continue to refer to Figure 5 and Figure 6 The angle adjustment mechanism 4 also includes a rotating shaft 48 and a tension spring 49, wherein: the rotating shaft 48 is connected between the output shaft of the angle adjustment motor 41 and the roller 42; the tension spring 49 is connected between the first pressure roller 44 and the rotating shaft 48.

[0063] Specifically, there are two rotating shafts 48, one at each end of the angle adjustment motor 41. One end of each rotating shaft 48 is fixedly connected to the output shaft of the angle adjustment motor 41 via a coupling, and the other end of each rotating shaft 48 is rotatably connected to the end wall of the mounting housing 1. The roller 42 is mounted and fixed on the rotating shaft 48. The second pressure roller 45 is located between the first pressure roller 44 and the rotating shaft 48. One end of the tension spring 49 is hooked on the central axis of the first pressure roller 44, and the other end of the tension spring 49 is hooked on the rotating shaft 48.

[0064] The above structure enables the tension spring 49 to provide an elastic force to drive the first pressing roller 44 to move in a direction close to the second pressing roller 45, so as to ensure that the relative position of the angle adjustment chain 3 and the roller 42 is not easily changed.

[0065] In the blinds provided in this application, the tension spring 49 is used to clamp the angle adjustment chain 3 by the first pressure roller 44 and the second pressure roller 45, and the mini electric push rod is mainly used to loosen the angle adjustment chain 3 by the first pressure roller 44 and the second pressure roller 45, so as to be more convenient for users to use.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
