Figure 1 and Figure 2 As shown, the photovoltaic shutter includes a frame 1, a first fixed frame 2-1 is provided on one side of the frame 1, and a second fixed frame 2-2 is provided on the other side of the frame 1, and the corresponding positions of the first fixed frame 2-1 and the second fixed frame 2-2 are respectively provided with first connecting member assemblies and second connecting member assemblies arranged at equal intervals from top to bottom, and a plurality of photovoltaic assemblies are arranged between the first connecting member assembly and the second connecting member assembly, a first rotating link is provided on the first connecting member assembly, and a second rotating link is provided on the second connecting member assembly, and the first rotating link and the second rotating link are connected by a connecting rod (a transverse connecting rod can be provided at the top ends of the first rotating link and the second rotating link, so that a stable connection relationship is formed between the first rotating link and the second rotating link through the transverse connecting rod), and a driving mechanism is provided on the first fixed frame 2-1, and the driving mechanism cooperates with the first rotating link.

[0035] In this embodiment, Figure 3As shown, a substrate 5-1 is provided on the front of each photovoltaic module, and two leads, one positive and one negative, are led out of the substrate 5-1. The leads pass through the lead holes on the photovoltaic module to the back of the photovoltaic module, as shown in FIG. Figure 4 As shown, a wire rack 5-3 is provided on one side of the connector 5-2 located on the back of the photovoltaic module, and the lead wires penetrating into the back of the photovoltaic module are fixed in the wire rack 5-3, thereby fixing the photovoltaic module on the connector 5-2.

[0036] This embodiment controls the photovoltaic blinds by setting a driving mechanism 6, which can quickly respond to changes in external light conditions to automatically adjust the opening and closing angles of the blinds, thereby improving the convenience and efficiency of using the blinds. In addition, by setting the driving mechanism 6, the user can achieve effective management of indoor light and temperature without manual operation.

[0037] In another exemplary embodiment, Figure 5 and Figure 6 As shown, the driving mechanism 6 includes an upper end cover 6-7, a lower end cover 6-1, a screw rod 6-3, an upper bearing 6-10 and a lower bearing 6-2, wherein one end of the screw rod 6-3 is connected to the upper end cover 6-7 through the upper bearing 6-10, a driving motor 6-8 is arranged on the upper end cover 6-7, the other end of the screw rod 6-3 is connected to the lower end cover 6-1 through the lower bearing 6-2, a connecting seat 6-11 is arranged at the bottom of the lower end cover 6-1, a first connecting hole 6-12 is arranged on the connecting seat 6-11, and the connecting seat 6-11 is connected to the first fixed frame 2-1 through the first connecting hole 6-12.

[0038] Furthermore, a screw nut 6-4 is threadedly connected to the screw rod 6-3, a slider 6-5 is provided on the outer sleeve of the screw nut 6-4, a mounting groove 6-5-3 is provided on the slider 6-5, a mounting hole 6-5-4 is provided at the bottom of the mounting groove 6-5-3, the screw nut 6-4 is arranged in the mounting groove 6-5-3, and the screw nut 6-4 corresponds to the mounting hole 6-5-4, and the slider 6-5 is sleeved on the screw rod 6-3 through the mounting hole 6-5-4.

[0039] In this embodiment, the working principle of the driving mechanism is specifically described as follows:

[0040] When the screw rod 6-3 rotates axially under the drive of the driving motor 6-8, the screw nut 6-4 threadedly connected to the screw rod 6-3 moves linearly up and down along the screw rod 6-3, thereby causing the slider 6-5 sleeved on the outer periphery of the screw nut 6-4 to move linearly up and down accordingly. Since the first rotating link 4-1 is in contact with the lower end surface of the slider 6-5, when the screw rod 6-3 rotates axially in a first direction under the drive of the driving motor 6-8 (for example, the first direction is clockwise), the slider 6-5 moves linearly downward along the screw rod 6-3 along with the screw nut 6-4, and the slider 6-5 applies downward pressure to the first rotating link 4-1, forcing the first rotating link 4-1 to drive the second rotating link 4-2 to move downward, thereby driving the photovoltaic assembly to open. On the contrary, when the screw rod 6-3 rotates axially in the second direction driven by the driving motor 6-8 (for example, the second direction is counterclockwise), the slider 6-5 moves linearly upward along the screw rod 6-3 along with the screw nut 6-4. At this time, the pressure transmitted downward by the slider 6-5 to the first rotating link 4-1 gradually disappears, so that the first rotating link 4-1 drives the second rotating link 4-2 to gradually rebound and finally return to its original position, thereby driving the photovoltaic assembly to close.

[0041] In summary, this embodiment cleverly utilizes the natural elasticity of the rotating connecting rod, so that the photovoltaic component can be closed only by relying on the automatic rebound function of the rotating connecting rod without relying on the motor, thereby saving the power output of the motor and reducing operating costs.

[0042] It should be noted that a rubber gasket or a damper may be further provided at the connection between the drive motor 6-8 and the upper end cover 6-7 to reduce vibration and noise during operation of the drive motor 6-8, thereby improving the user experience.

[0043] In another exemplary embodiment, Figure 7 and Figure 8 As shown, a slide groove 6-5-5 is provided on the side of the slider 6-5 away from the screw rod 6-3, and the slide groove 6-5-5 is connected with the mounting groove 6-5-3. A stopper 6-5-8 is provided in the mounting groove 6-5-3, and one side of the stopper 6-5-8 is fitted with the screw rod nut 6-4, and the other side of the stopper 6-5-8 is integrally connected with a sliding block 6-5-7, and the sliding block 6-5-7 is provided in the slide groove 6-5-5.

[0044] Furthermore, a positioning groove 6-5-6 is also provided on the side of the sliding block 6-5 away from the screw rod 6-3, and the positioning groove 6-5-6 is located above the sliding groove 6-5-5 and is connected with the sliding groove 6-5-5. A positioning screw 6-5-13 is provided in the positioning groove 6-5-6, and the positioning screw 6-5-13 is connected to the sliding block 6-5-7 through a hole provided on the sliding block 6-5-7.

[0045] Furthermore, the first connecting column 6-5-9 and the second connecting column 6-5-10 are respectively provided at both ends of the side where the stop block 6-5-8 is connected to the sliding block 6-5-7, and the first connecting column 6-5-9 and the second connecting column 6-5-10 are respectively matched with the second connecting holes 6-5-14 provided on the inner wall of the mounting groove 6-5-3 and located on both sides of the sliding groove 6-5-5.

[0046] In this embodiment, the slider 6-5 with the above-mentioned structural features can adapt to various types of lead screw nuts with the same inner diameter but different outer diameters. For example, when it is necessary to replace a lead screw nut with the same inner diameter but a larger outer diameter (for example, during the use of the shutters, the existing lead screw nut is worn out due to the heavy load and cannot meet the requirements of long-term stable operation of the shutters. Replacing the lead screw nut with a larger outer diameter can increase its contact area with the lead screw without changing its inner diameter, thereby improving the bearing capacity and overall mechanical stability of the entire drive mechanism, thereby ensuring the long-term and reliable operation of the shutters), there is no need to completely disassemble the positioning screw 6-5-13, only need to loosen it moderately while maintaining the connection with the sliding block 6-5-7 (for example, the positioning screw 6-5-13 can be rotated half a circle or one circle, depending on the actual situation), so that the positioning screw 6-5-13 obtains a certain degree of freedom of movement. Then, under the guidance of the positioning groove 6-5-6, the positioning screw 6-5-13 is appropriately slid in the positioning groove 6-5-6 along the outer side of the slider 6-5 until it reaches a suitable position suitable for the outer diameter of the new nut, and then the positioning screw 6-5-13 is tightened to complete the positioning of the sliding block 6-5-7. It should be noted that since the sliding block 6-5-7 and the positioning screw 6-5-13 maintain a connection relationship, during the sliding process of the positioning screw 6-5-13, it can drive the sliding block 6-5-7 to slide in the sliding groove 6-5-5. As the sliding block 6-5-7 slides in the sliding groove 6-5-5, the stopper 6-5-8 integrally connected therewith moves in the same direction as the sliding block 6-5-7 in the mounting groove 6-5-3 at the same time. This linkage effect can adjust the space in the mounting groove 6-5-3 to create enough accommodation space to accommodate a screw nut with a larger outer diameter. After the above adjustment, the internal space of the installation groove 6-5-3 is expanded to a certain extent through the coordinated movement of the sliding block 6-5-7 and the stopper 6-5-8, so that a new screw nut with a larger outer diameter can be accommodated and stably installed without making major changes to the slider body or other components. It should also be noted that the first connecting column 6-5-9 and the second connecting column 6-5-10 are respectively embedded in the second connecting holes 6-5-14 on both sides of the installation groove 6-5-3, which play a role in fixing the relative positions of the sliding block 6-5-7 and the stopper 6-5-8, thereby ensuring that when the slider 6-5 moves up and down with the screw nut 6-4, the various components therein maintain a stable geometric relationship, thereby achieving precise matching between the screw nut 6-4 and the slider 6-5.In addition, the presence of the first spring 6-5-11 and the second spring 6-5-12 can provide an elastic buffering effect for the slider 6-5. When the slider 6-5 moves up and down with the lead screw nut 6-3, especially when it reaches the limit of the stroke or encounters resistance, the first spring 6-5-11 and the second spring 6-5-12 can absorb impact force and vibration, reduce the force directly transmitted to other parts of the drive mechanism, thereby improving the stability and durability of the drive mechanism. Furthermore, when it is necessary to replace the screw nut with a different outer diameter, by adjusting the position of the positioning screw 6-5-13, the sliding block 6-5-7 and the stop block 6-5-8 will move in coordination along the slide groove 6-5-5 to adapt to the diameter change of the screw nut. During this coordinated movement, the first spring 6-5-11 and the second spring 6-5-12 respectively surrounding the first connecting column 6-5-9 and the second connecting column 6-5-10 allow the first connecting column 6-5-9 and the second connecting column 6-5-10 to have a certain floating space in the second connecting hole 6-5-14 due to their elastic effect. This floating space can make the cooperation between the slider 6-5 and the screw nut 6-4 more flexible. Even if the outer diameter of the screw nut 6-4 is slightly different, the first spring 6-5-11 and the second spring 6-5-12 can fill or adapt to these tiny size changes through their own compression or extension, thereby ensuring that there is always good contact between the slider 6-5 and the screw nut 6-4.

[0047] The above content introduces in detail the working principle of the slider 6-5 when adapting to the screw nut with an increased outer diameter. Therefore, when it is necessary to replace a nut with the same inner diameter but a smaller outer diameter (for example, it is necessary to add other components to the existing shutter structure and replace the nut with a smaller outer diameter to make room for other components), it is only necessary to adjust the positioning screw 6-5-13 in the positioning groove 6-5-6 in the opposite direction to the previous direction, that is, to slide the positioning screw 6-5-13 in the positioning groove 6-5-6 along the direction of the mounting groove 6-5-3 appropriately, so as to create a suitable space in the mounting groove 6-5-3 to accommodate the screw nut with a smaller outer diameter.

[0048] In summary, this embodiment fine-tunes the position of the positioning screw 6-5-13 so that the sliding block 6-5-7 and the stop block 6-5-8 form a cooperative sliding mechanism, so that the mounting groove 6-5-3 can adapt to screw nuts with different outer diameters. Without replacing the slider or other major structural components, screw nuts of different specifications can be easily replaced according to actual application requirements, which not only simplifies the maintenance and upgrade process, but also reduces the changes to the entire drive mechanism. It is an efficient and economical design solution.

[0049] On the basis of the above embodiment, in order to facilitate the maintenance of the slider 6-5, the present application provides a Figure 7 and Figure 8 The slider 6-5 shown in FIG. 1 is improved in structure. The improved slider 6-5 is as shown in FIG. Figures 9 to 11 As shown. Figures 9 to 11 In the figure, the slider 6-5 can be disassembled into a first slider body 6-5-1 and a second slider body 6-5-2, wherein a first plug block 6-5-20 is provided at one end of the first slider body 6-5-1 away from the slide groove 6-5-5, a first slot 6-5-21 is provided at one end of the second slider body 6-5-2 away from the slide groove 6-5-5, and the first plug block 6-5-20 and the first slot 6-5-21 cooperate with each other; a second slot 6-5-23 is provided at one end of the first slider body 6-5-1 close to the slide groove 6-5-5, a second plug block 6-5-22 is provided at one end of the second slider body 6-5-2 close to the slide groove 6-5-5, and the second plug block 6-5-22 and the second slot 6-5-23 cooperate with each other.

[0050] Further, the second slot 6-5-23 is provided with a first socket 6-5-24, the second plug block 6-5-22 is provided with a second socket 6-5-25, and the first socket 6-5-24 is provided with an adjustment component, the adjustment component includes a step shaft 6-5-17, a nut 6-5-18, a pin 6-5-15 and a third spring 6-5-16, wherein the step shaft 6-5-17 is threadedly connected to the first socket 6-5-24 (the thread height of the step shaft 6-5-17 is not higher than the thread height of the first socket 6-5-24, so that when the slider 6-5 is disassembled, the nut 6-5-18 will be completely retracted in the step shaft 6-5-17 when it moves upward, and will not cause damage to the second socket 6-5-25. Interference), the nut 6-5-18 is arranged in the step shaft 6-5-17 and the lower end of the nut 6-5-18 extends into the second socket 6-5-25, the nut 6-5-18 is provided with an internal thread, the lower end of the pin 6-5-15 is provided with an external thread, the pin 6-5-15 is threadedly connected with the nut 6-5-18; the pin 6-5-15 is also sleeved with a third spring 6-5-16, and the upper end face of the third spring 6-5-16 is aligned with the lower end face of the step shaft 6-5-17, the lower end face of the third spring 6-5-16 is aligned with the upper end face of the nut 6-5-18, the pin 6-5-15, the third spring 6-5-16 and the nut 6-5-18 form a pre-compression structure.

[0051] In this embodiment, a handle 6-5-19 is provided at the upper end of the pin shaft 6-5-15, and the operator can use the rotation of the handle 6-5-19 to control the up and down movement of the pin shaft 6-5-15. For example, when the slider 6-5 needs to be disassembled, the handle 6-5-19 needs to be rotated in a first direction (for example, the first direction is clockwise). By rotating the handle 6-5-19, the pin shaft 6-5-15 can be moved upward and disengaged from the second socket 6-5-25. In this process, the third spring 6-5-16 in a pre-compression state will be further compressed, so that its elastic force increases, and then the nut 6-5-18 moves upward with the pin shaft 6-5-15 to gradually disengage from the second socket 6-5-25 and completely retract into the stepped shaft 6-5-17. As the nut 6-5-18 moves upward, the connection between the first slider body 6-5-1 and the second slider body 6-5-2, which were originally locked with each other through the first plug 6-5-20 and the first slot 6-5-21, and the second plug 6-5-22 and the second slot 6-5-23, will be gradually loosened. When the pin 6-5-15 moves upward to a sufficient position, the connection between the first slider body 6-5-1 and the second slider body 6-5-2 will be completely released, and the first slider body 6-5-1 and the second slider body 6-5-1 can be separated. On the contrary, when it is necessary to install the slider 6-5, first bring the first slider body 6-5-1 and the second slider body 6-5-2 close to each other and align them to ensure that the first plug 6-5-20 and the first slot 6-5-21, and the second plug 6-5-22 and the second slot 6-5-23 are correctly docked. Then, rotate the handle 6-5-19 in the second direction (for example, counterclockwise) to move the pin 6-5-15 downward. At this time, the third spring 6-5-16 in compression will gradually release the pressure and push the nut 6-5-18 toward the second socket 6-5-25 until it contacts and locks, thereby reconnecting the first slider body 6-5-1 and the second slider body 6-5-2 tightly together.

[0052] This embodiment realizes the detachable connection of the slider by setting an adjustment component, so that when the user needs to clean, inspect or replace damaged parts, the user can quickly disassemble the slider and perform targeted repairs or replacements, which greatly shortens the maintenance time and reduces the maintenance cost.

[0053] In another exemplary embodiment, Figure 6As shown, the driving mechanism also includes an upper limit switch 6-9 and a lower limit switch 6-6, wherein the upper limit switch 6-9 is arranged on one side of the lower end surface edge of the upper end cover 6-7 and corresponds to the upper end surface edge of the slider 6-5, and the lower limit switch 6-6 is arranged on the first fixed frame and corresponds to the lower end surface edge of the slider 6-5, and the upper limit switch 6-9 and the lower limit switch 6-6 are correspondingly arranged on a straight line.

[0054] In this embodiment, when the slider 6-5 moves linearly downward along the screw 6-3 with the screw nut 6-4 to the maximum position of its stroke, the slider 6-5 will touch the lower limit switch 6-6 and trigger the switch action, which will send an electrical signal to the drive motor 6-8 to stop the drive motor 6-8, thereby avoiding mechanical damage or unnecessary energy consumption of the photovoltaic component due to exceeding the predetermined stroke during the opening process, that is, the lower limit switch 6-6 can ensure that the opening state of the photovoltaic component does not exceed the predetermined safety limit.

[0055] In the process that the slider 6-5 moves linearly upward along the screw 6-3 with the screw nut 6-4 and drives the photovoltaic assembly to close, when the photovoltaic assembly is closed to the maximum limit, the slider 6-5 will touch the upper limit switch 6-9, thereby preventing the slider 6-5 from further downward movement. That is, the upper limit switch 6-9 can prevent the slider 6-5 from over-squeezing the first rotating link and causing the photovoltaic assembly to be damaged due to over-closing.

[0056] In summary, the upper limit switch 6-9 and the lower limit switch 6-6 jointly ensure that the movement range of the photovoltaic component is strictly controlled between the preset upper and lower limit positions, which not only protects the driving mechanism from overload damage, but also ensures the smoothness and accuracy of the driving process.

[0057] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
