Description

Technical Field

[0001] This invention relates to a solar louver, and more particularly to an anisoaxial swing type solar louver. Prior Technology

[0002] In recent years, with the significant increase in global environmental awareness, the demand for green energy has been growing. Among the many green energy sources, solar energy has attracted much attention due to its clean and renewable characteristics. Currently, solar modules (solar panels) have been widely deployed in open spaces and unshaded areas such as building rooftops to ensure direct absorption of sunlight and achieve high-efficiency power generation.

[0003] With the continued growth in electricity demand, relying solely on rooftop solar panels is no longer sufficient to meet the increasing energy needs. Furthermore, in urban areas with numerous high-rise buildings, rooftop space is limited, making solar panel installation challenging. Therefore, existing technologies include mounting solar panels on louvered slats. By adjusting the angle of the louvered slats, the solar panels can be aligned with sunlight as much as possible, thereby maximizing power generation efficiency.

[0004] However, traditional venetian blinds have slats set along only a single axis, meaning the slats can only swing vertically or horizontally. In most cases, the sun's path from sunrise to sunset does not traverse the zenith perpendicularly, but remains constant with seasonal changes and latitude variations. During the sun's movement, the vertically swinging slats can only respond to changes in the angle of sunlight. Similarly, the horizontally swinging slats can only respond to changes in the angle of sunlight. In other words, traditional venetian blinds cannot simultaneously handle changes in both vertical and horizontal light angles, thus limiting their power generation efficiency. Summary of the Invention

[0005] In the prior art, traditional venetian blinds are configured with blades along only a single axis, which limits their power generation efficiency due to their inability to simultaneously handle changes in both vertical and horizontal light angles. The main objective of this invention is to provide an anisoaxial oscillating solar venetian blind. This blind utilizes two sets of blades with opposite axes in the window frame, allowing the blades to oscillate up or down or oscillate horizontally as the sun moves. This simultaneously addresses changes in both vertical and horizontal light angles, ensuring that the first and second incident sunlight intensities are within their respective relative maximum ranges, thereby achieving optimal power generation efficiency.

[0006] Accordingly, the necessary technical means adopted by the present invention to solve the problems of the prior art is to provide an anaxially swaying type solar venetian blind (hereinafter referred to as "solar venetian blind"), comprising a window frame, a first blade group, a second blade group, a plurality of solar panels, and a control module. The window frame has a first assembly space and a second assembly space. Preferably, the window frame includes a window frame body and two bases. The window frame body has the first assembly space and the second assembly space, and the two bases are respectively fixed to both sides of the window frame body to support the window frame body.

[0007] The first blade assembly includes a plurality of first blades, a first blade driving module, and a first light sensing module. The first blades are pivotally connected to the window frame along a first axis within a first assembly space. Preferably, each of the aforementioned first blades includes a first blade body and a first pivot. The first pivot is fixed to the first blade body and passes through the window frame, thereby pivotally connecting the first blade to the window frame.

[0008] The first blade drive module is powered by the first blade to drive the first blade to oscillate. Preferably, the first blade drive module includes a first motor, a plurality of first servo arms, and a plurality of first links. The first motor is mounted on the window frame and electrically connected to the control module. The first servo arms are respectively fixed to the output shaft and the first rotating shaft of the first motor. The first links are pivotally connected at both ends to adjacent first servo arms. When the output shaft of the first motor rotates, power is transmitted to the first blade via the first servo arms and the first links to drive the first blade to oscillate.

[0009] A first light sensing module is disposed on one of the aforementioned first blades, and is used to send a first sun-tracking signal when it senses and determines that a first incident sunlight intensity is outside a first relative maximum value range. The first light sensing module includes two first photosensitive elements and a first partition. The first photosensitive elements are disposed on the aforementioned first blades, and the first partition separates the first photosensitive elements from the first blades.

[0010] The second blade assembly includes a plurality of second blades, a second blade driving module, and a second light sensing module. The second blades are pivotally connected to the window frame in the second assembly space along a second axis orthogonal to the first axis. Preferably, each of the aforementioned second blades includes a second blade body and a second pivot. The second pivot is fixed to the second blade body and passes through the window frame to pivotally connect the second blade to the window frame.

[0011] The second blade drive module is powered by the second blade to drive its oscillation. Preferably, the second blade drive module includes a second motor, a plurality of second servo arms, and a plurality of second links. The second motor is mounted on the window frame and electrically connected to the control module. The second servo arms are respectively fixed to the output shaft and the second rotating shaft of the second motor. The second links are pivotally connected at both ends to adjacent first servo arms. When the output shaft of the second motor rotates, power is transmitted to the second blade via the second servo arms and second links to drive its oscillation.

[0012] A second light sensing module is disposed on one of the aforementioned second blades, for transmitting a second sun-tracking signal when it senses and determines that a second incident sunlight intensity is outside a second relative maximum range. Preferably, the second light sensing module includes two second photosensitive elements and a second partition. The second photosensitive elements are disposed on the aforementioned second blades, and the second partition separates the second photosensitive elements from the second blades.

[0013] Solar panels are respectively disposed on the first blade and the second blade. A control module is electrically connected to the first light sensing module, the second light sensing module, the first blade driving module, and the second blade driving module. After receiving the first solar tracking signal, the control module drives the first blade to swing, thereby keeping the first incident sunlight intensity within the first relative maximum range; and after receiving the second solar tracking signal, the control module drives the second blade to swing, thereby keeping the second incident sunlight intensity within the second relative maximum range.

[0014] Based on the aforementioned necessary technical means, the following auxiliary technical means can be derived. Preferably, the solar louver further includes an energy storage module. The energy storage module is electrically connected to the solar panel to receive and store the electricity generated by the solar panel after being exposed to sunlight.

[0015] In summary, the antiaxial swing type solar louver provided by the present invention uses two sets of blades with opposite axes in the window frame, so that the blades can swing up or down or horizontally as the sun moves, thereby simultaneously responding to changes in the vertical and horizontal angles of light, so that the intensity of the first incident sunlight and the intensity of the second incident sunlight are located in the first relative maximum value range and the second relative maximum value range, respectively, thereby achieving the best power generation efficiency.

Only a few preferred embodiments are listed for specific explanation. These embodiments are only used to conveniently and clearly assist in explaining the purpose and effects of the embodiments of the present invention.

[0020] As shown in Figures 1 to 7, an anisoaxial swing type solar louver (hereinafter referred to as "solar louver") 100 includes a window frame 1, a first blade group 2, a second blade group 3, a plurality of solar panels (only two of them, 4a and 4b, are shown) and a control module 5.

[0021] The window frame 1 has a first assembly space 11 and a second assembly space 12. In this embodiment, the window frame 1 has a window frame body 13 and two bases 14a and 14b. The window frame body 13 has the first assembly space 11 and the second assembly space 12. The bases 14a and 14b are fixed to both sides of the window frame body 13 to support the window frame body 13. In other embodiments, the window frame body 13 can be directly installed on the wall of the building without the need for bases 14a and 14b.

[0022] The first blade assembly 2 includes a plurality of first blades (only one first blade 21 is indicated), a first blade driving module 22, and a first light sensing module 23. The first blade 21 is pivotally connected to the window frame 1 in the first assembly space 11 along a first axis A1. In this embodiment, an XYZ coordinate system is established with the window frame, and the first axis A1 extends along the Y direction. That is, the first blade 21 is capable of pitching.

[0023] In this embodiment, the first blade 21 includes a first blade body 211 and a first rotating shaft 212. The first rotating shaft 212 is fixed to the first blade body 211 and passes through the window frame 1, so that the first blade 21 is pivotally connected to the window frame 1. In addition, in order to prevent the first blade 21 from absorbing excess heat, preferably, the first blade 21 is made of wood, a material with low thermal conductivity.

[0024] The first blade drive module 22 is poweredly connected to the first blade 21 to drive the first blade 21 to oscillate. In this embodiment, the first blade drive module 22 includes a first motor 221, a plurality of first servo arms (only one first servo arm 222 is shown), and a plurality of first links (only one first link 223 is shown). In other embodiments, the first blade drive module 22 can use a variety of different power transmission structures to control the oscillation of the first blade 21.

[0025] The first motor 221 is mounted on the window frame 1 and electrically connected to the control module 5. The first servo arm fixes the output shaft of the first motor 221 and the first rotating shaft respectively. The first connecting rod is pivotally connected at both ends to the adjacent first servo arms. When the output shaft of the first motor 221 rotates, the power is transmitted to the first blade through the first servo arm and the first connecting rod to drive the first blade to oscillate.

[0026] A first light sensing module 23 is disposed on one of the first blades (in this embodiment, it is disposed on the first blade 21) to send a first sun-tracking signal S1 (shown in Figure 7) when it senses and determines that a first incident light intensity is outside a first relative maximum value range. In this embodiment, the first incident light intensity refers to the light intensity generated by the first incident light IL1 (sunlight) (shown in Figure 8A) illuminating the first blade 21.

[0027] Since this invention is a solar power generation device, the so-called light intensity directly corresponds to the amount of electricity generated. Therefore, when the first incident light intensity is outside the first relative maximum range, the current orientation (oscillation angle) of the first blade 21 cannot achieve the current maximum power generation efficiency. Conversely, when the first incident light intensity is within the first relative maximum range, the current orientation of the first blade 21 can achieve the current maximum power generation efficiency. It should be noted that the upper limit of light intensity varies with many factors (such as season, latitude, or weather), therefore, a relative maximum range is used for judgment rather than an absolute maximum value. The specific sensing and judgment logic will be described in subsequent paragraphs.

[0028] In this embodiment, the first light sensing module 23 includes two first photosensitive elements 231a and 231b and a first partition 232. The first photosensitive elements 231a and 231b are disposed on the first blade 21, and the first partition 232 separates the first photosensitive elements 231a and 231b on the first blade 21. In addition, since the first light sensing module 23 swings with the first blade 21, in this embodiment, an X1-Y1-Z1 coordinate system (labeled in Figure 5) is established based on the first light sensing module 23 for use in the subsequent description of the incident light angle.

[0029] In this embodiment, both the first photosensitive elements 231a and 231b are photoresistors, but this is not a limitation. In other embodiments, other elements used to detect light intensity, such as photodiodes, can be used. Since the structure and working principle of photoresistors are not claimed in this invention, they will not be described in detail in this embodiment.

[0030] The second blade assembly 3 includes a plurality of second blades (only one second blade 31 is indicated), a second blade driving module 32, and a second light sensing module 33. The second blade 31 is pivotally connected to the window frame 1 in the second assembly space 12 along a second axis A2 orthogonal to the first axis A1. In this embodiment, the second axis A2 extends along the Z direction. That is, the second blade 31 is capable of horizontal oscillation.

[0031] In this embodiment, the second blade 31 includes a second blade body 311 and a second pivot 312. The second pivot 312 is fixed to the second blade body 311 and passes through the window frame 1, so that the second blade 31 is pivotally connected to the window frame 1. In addition, in order to prevent the second blade 31 from absorbing excess heat, it is preferable that the second blade 31 is made of wood, a material with low thermal conductivity.

[0032] The second blade drive module 32 is poweredly connected to the second blade 31 to drive the second blade 31 to oscillate. In this embodiment, the second blade drive module 32 includes a second motor 321, a plurality of second servo arms (only one second servo arm 322 is shown), and a plurality of second links (only one second link 323 is shown). In other embodiments, the second blade drive module 32 can use a variety of different power transmission structures to control the oscillation of the second blade 31.

[0033] The second motor 321 is mounted on the window frame 1 and electrically connected to the control module 5. The second servo arm fixes the output shaft of the second motor 321 and the second rotating shaft respectively. The second connecting rod is pivotally connected at both ends to the adjacent second servo arms. When the output shaft of the second motor 321 rotates, the power is transmitted to the second blade through the second servo arm and the second connecting rod to drive the second blade to oscillate.

[0034] The second light sensing module 33 is disposed on one of the second blades (in this embodiment, it is disposed on the second blade 31) to send out a second sun-tracking signal S2 (shown in Figure 7) when it senses and determines that a second incident light intensity is outside a second relative maximum value range. In this embodiment, the second incident light intensity refers to the light intensity generated by the second incident light IL2 (sunlight) (shown in Figure 9A) illuminating one of the second blades 31.

[0035] Since this invention is a solar power generation device, the so-called light intensity directly corresponds to the amount of electricity that can be generated. Therefore, the fact that the second incident light intensity is outside the second relative maximum range means that the current orientation (oscillation angle) of the second blade 31 cannot achieve the current maximum power generation efficiency. Conversely, when the second incident light intensity is within the second relative maximum range, the current orientation of the second blade 31 can achieve the current maximum power generation efficiency. It should be noted that the upper limit of light intensity varies with many factors (such as season, latitude, or weather), therefore, a relative maximum range is used for judgment rather than an absolute maximum value. The specific sensing and judgment logic will be described in subsequent paragraphs.

[0036] In this embodiment, the second light sensing module 33 includes two second photosensitive elements 331a and 331b and a second partition 332. The second photosensitive elements 331a and 331b are disposed on the second blade 31, and the second partition 332 separates the second photosensitive elements 331a and 331b while being disposed on the second blade 31. In addition, since the second light sensing module 33 swings with the second blade 31, in this embodiment, an X2-Y2-Z2 coordinate system (labeled in Figure 6) is established based on the second light sensing module 33 for use in the subsequent description of the incident light angle.

[0037] In this embodiment, both the second photosensitive elements 331a and 331b are photoresistors, but this is not a limitation. In other embodiments, they can be other elements used to detect light intensity, such as photodiodes. Since the structure and working principle of photoresistors are not claimed in this invention, they will not be described in detail in this embodiment.

[0038] Solar panels are respectively disposed on the first blade and the second blade (in this embodiment, solar panel 4a is disposed on the first blade 21 and solar panel 4b is disposed on the second blade 31) to generate electricity when exposed to sunlight. The structure and working principle of the solar panels are not claimed in this invention and will not be described in detail in this embodiment.

[0039] The control module 5 is electrically connected to the first light sensing module 23, the second light sensing module 33, the first blade driving module 22, and the second blade driving module 32. In this embodiment, the control module 5 is actually electrically connected to the first motor 221, the second motor 321, the first photosensitive elements 231a and 231b, and the second photosensitive elements 331a and 331b.

[0040] The control module 5 is used to, upon receiving the first sun-tracking signal S1, cause the first blade drive module 22 to drive the first blade to swing, thereby keeping the first incident sunlight intensity within the first relative maximum range; and to, upon receiving the second sun-tracking signal S2, cause the second blade drive module 32 to drive the second blade to swing, thereby keeping the second incident sunlight intensity within the second relative maximum range. The specific control logic will be described in subsequent paragraphs. In this embodiment, the control module 5 includes an Arduino control board. In other embodiments, the control module 5 may include at least one of a control board, a control chip, and a control circuit.

[0041] The solar-powered blind 100 in this embodiment further includes an energy storage module 6. The energy storage module 6 is electrically connected to the solar panel to receive and store the electricity generated by the solar panel after being exposed to sunlight. Specifically, the energy storage module 6 includes a solar power controller (MPPT), a lead-acid battery, a switch, and an inverter. The structure and working principle of the energy storage module 6 are prior art and not claimed in this invention; therefore, they will not be described further in this embodiment.

[0042] In addition to connecting electricity to the energy storage module 6, the solar panels can also be electrically connected to the first motor 221, the second motor 321, and the control module 5 as auxiliary power. Furthermore, the solar panels can be directly connected to the mains power grid for use without being stored through the energy storage module 6.

[0043] Next, the sensing, judgment, and control logic of the automatic sun-tracking blades will be explained. Please refer to Figures 8A to 9B. Figures 8A and 8B are cross-sectional schematic diagrams of the first light sensing module of the anisoaxial oscillating solar blind of the preferred embodiment of the present invention; and Figures 9A and 9B are cross-sectional schematic diagrams of the second light sensing module of the anisoaxial oscillating solar blind of the preferred embodiment of the present invention.

[0044] As shown in Figure 8A, when the first incident light IL1 (sunlight) shines on the first blade 21, its component in the X1-Z1 plane forms a first angle R1 with the first blade 21. In most cases, the first incident light IL1 also has a component in the Y1 direction. When the first angle R1 deviates from 90 degrees (when the component of the first incident light IL1 in the X1-Z1 plane obliquely strikes the first blade 21), a portion of the first incident light IL1 is blocked by the first partition 232, forming a shadow region SA. The shadow region SA blocks one of the first photosensitive elements.

[0045] In this embodiment, the first included angle R1 is less than 90 degrees, meaning the shadow region SA covers the first photosensitive element 231a. When the first photosensitive element 231a is covered by the shadow region SA, the corresponding photosensitive parameter (resistance value) generated by the first photosensitive element 231a will be different from the photosensitive parameter generated by the first photosensitive element 231b. In other words, when the photosensitive parameter of the first photosensitive element 231a is different from the photosensitive parameter of the first photosensitive element 231b, it can be determined that the component of the first incident light IL1 in the X1-Z1 plane is not perpendicularly incident (the first included angle R1 is 90 degrees or close to 90 degrees).

[0046] Because solar panels have the highest power generation efficiency when incident perpendicularly (when incident at an angle, they cannot reach maximum efficiency due to reflection and scattering), it can be inferred that the intensity of the first incident sunlight is outside the first relative maximum range when it is determined that the incident sunlight is not perpendicular. Next, when it is determined that the photosensitive parameters of the first photosensitive element 231a are different from those of the first photosensitive element 231b, a first sun-tracking signal S1 is sent to the control module 5. Upon receiving the first sun-tracking signal S1, the control module 5 causes the first blade drive module 22 (first motor 221) to drive the first blade 21 to swing.

[0047] The direction of the swing can be determined from the difference in photosensitive parameters. Taking a photoresistor (the greater the light, the smaller the resistance) as an example, when the resistance value of the first photosensitive element 231a is large (the difference is a positive number), it means that the first photosensitive element 231a is blocked by shadow, which means that the first blade 21 needs to swing in the direction that can increase the first included angle R1, and vice versa.

[0048] As shown in Figure 8B, when the photosensitive parameters are the same or slightly different, the first blade 21 stops swinging, and it is determined that the component of the first incident light IL1 on the X1-Z1 plane is perpendicularly incident on the first blade 21 (the first included angle R1' is 90 degrees or close to 90 degrees), that is, the intensity of the first incident sunlight is in the first relative maximum range, and thus has the maximum power generation efficiency.

[0049] As shown in Figure 9A, when the second incident light IL2 illuminates the second blade 31, its component in the X2-Z2 plane has a second included angle R2 with the second blade 31. In most cases, the second incident light IL2 also has a component in the Y2 direction. When the control module 5 receives the second sun-tracking signal S2, it causes the second blade drive module 32 (second motor 321) to drive the second blade 31 to swing.

[0050] As shown in Figure 9B, when the photosensitivity parameters are the same or have only slight differences, the second blade 31 stops oscillating, and it is determined that the component of the second incident light IL2 in the X2-Z2 plane is perpendicularly incident on the second blade 31 (the second included angle R2' is 90 degrees or close to 90 degrees), meaning that the intensity of the second incident sunlight is in the second relative maximum range, thus achieving the maximum power generation efficiency. Since the structure, working principle, and driving logic of the second light sensing module 33 and the second blade driving module 32 are the same as or similar to those of the first blade driving module 22 and the first light sensing module 23, please refer to the description in the corresponding paragraphs; they will not be repeated in this embodiment.

[0051] The sensing, judgment, and control logic of the automatic sun-tracking blades has now been explained. Next, the mode switching of the solar louver 100 will be explained. Please refer back to Figure 1. As shown in Figure 1, the control module 5 also includes a knob 51 and a three-position switch (not shown), which can be switched between a sun-tracking mode, a manual mode, and a closed mode. In this embodiment, the three-position switch corresponds to the sun-tracking mode, the manual mode, and the closed mode, respectively, and can be switched as needed (for example, after sunset, switching from the sun-tracking mode to the manual mode or the closed mode). The structure and working principle of the three-position switch are not claimed in this invention and will not be described in detail in this embodiment.

[0052] In sun-tracking mode, control module 5 controls the oscillation of the first and second blades based on the first sun-tracking signal S1 and the second sun-tracking signal S2. For details on the related sensing, judgment, and control logic, please refer to the explanation in the preceding paragraphs; it will not be repeated here. Sun-tracking mode is suitable for daytime conditions with sunlight, and can automatically adjust the blade angle to maximize the power generation efficiency of the solar panels.

[0053] In manual mode, control module 5 stops receiving the first sun-tracking signal S1 and the second sun-tracking signal S2, or ignores them after receiving them. At this time, the oscillation angle of the blades can be adjusted by rotating knob 51, thereby improving air convection and regulating indoor temperature. Manual mode is suitable for nighttime or cloudy days when there is no sunlight.

[0054] In practice, knob 51 can correspond to both the first and second blades simultaneously; that is, when knob 51 is turned, the first and second blades will oscillate synchronously in a controlled manner. Furthermore, an additional knob (not shown) can be added, so that the two knobs correspond to the first and second blades respectively. This means that the angles of the first and second blades can be adjusted separately to obtain a better convection effect. Additionally, a switch can be added to switch the control object of knob 51, thereby allowing separate control of the first and second blades when only one knob 51 is used.

[0055] In the off mode, the power supply (including mains power and solar power) to the control module 5, the first motor 221, and the second motor 321 is cut off, thereby saving the power consumed by these components when they are in standby mode. The off mode is suitable for situations where the solar louver 100 is not used for a long time, and can effectively save energy.

[0056] In summary, the solar louver 100 provided by the present invention utilizes two sets of blades (a first set of blades 2 and a second set of blades 3) with opposite axes in the window frame 1. This allows the blades to swing up or down or horizontally as the sun moves, thereby simultaneously responding to changes in the vertical and horizontal angles of light. This ensures that the intensity of the first incident sunlight and the intensity of the second incident sunlight are located within the first and second relative maximum ranges, respectively, thereby achieving optimal power generation efficiency.

[0057] The detailed description of the above preferred embodiments is intended to more clearly illustrate the features and spirit of the present invention, and is not intended to limit the scope of the present invention by the preferred embodiments disclosed above. On the contrary, the aim is to cover various modifications and equivalent arrangements within the scope of the patent claims made by the present invention.
