Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to a movable sunshade photovoltaic panel. Background Technology

[0002] More and more companies are installing photovoltaic (PV) modules on the exterior facades of office buildings, using existing walls as the installation base and employing mechanical components such as brackets, purlins, and clamps for installation. Therefore, enhancing the application value and innovative significance of PV modules on building facades will inevitably become a trend in this direction.

[0003] Current applications of photovoltaic (PV) panels installed on building facades are all fixed, resulting in low utilization of solar energy and consequently low power generation efficiency. Furthermore, the use of PV panels is solely for photovoltaic power generation and lacks other auxiliary functions. Meanwhile, sunshades installed on the walls between windows are widely used to control indoor lighting, but ordinary sunshades only block sunlight and do not convert solar energy into electrical energy.

[0004] Therefore, in view of the common problems of photovoltaic panels and sunshades, how to improve the light energy utilization rate of photovoltaic panels and develop movable sunshade photovoltaic panels that can replace the sunshade function of sunshades is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to provide a movable shading photovoltaic panel that can provide shading while generating photovoltaic power, and can adjust its angle according to the incident angle of sunlight to enhance the light energy utilization rate of the photovoltaic panel.

[0006] To achieve the above objectives, this application provides a movable sunshade panel, installed on the outer wall above a window, comprising:

[0007] Photovoltaic panels;

[0008] Mounting plates are located on both sides of the photovoltaic panel, and the side walls of the mounting plates are provided with a first elongated hole that penetrates through itself and is vertically arranged.

[0009] The power mechanism, fixed to the end face of the mounting plate away from the photovoltaic panel, includes an electric cylinder, the actuating end of which performs an extension / retraction movement in the vertical direction;

[0010] An actuator for connecting the actuating end and the photovoltaic panel includes a crank rocker arm and a connecting shaft connecting the crank rocker arm and the actuating end. The non-end of the crank rocker arm is rotatably connected to the side wall of the mounting plate through a bearing seat. The end of the crank rocker arm is provided with a second elongated hole that penetrates itself. The end of the connecting shaft opposite to the actuating end extends into the second elongated hole and is slidably connected to the second elongated hole.

[0011] The photovoltaic panel has sliding pins that pass through the first elongated hole and slide therethrough on its two sides, and rotating pins that are hinged to the end of the crank rocker arm away from the second elongated hole.

[0012] Preferably, the extension / retraction motion of the actuating end causes the crank rocker arm to rotate around the bearing seat as the center, and causes the lower end of the photovoltaic panel to move closer to / away from the outer wall, while simultaneously causing the sliding pin to move vertically upward / downward within the first elongated hole.

[0013] Preferably, the sliding pin is located at the upper part of the side of the photovoltaic panel, the rotating pin is located at the middle part of the side of the photovoltaic panel, and the two sliding pins located on the two sides of the photovoltaic panel are symmetrically arranged about the photovoltaic panel, and the two rotating pins located on the two sides of the photovoltaic panel are symmetrically arranged about the photovoltaic panel.

[0014] Preferably, the crank rocker arm is provided with a rotating shaft that passes through the side wall of the mounting plate and is rotatably connected to the bearing seat, and the crank rocker arm is divided into two sections by the rotating shaft, and the included angle between the two sections of the crank rocker arm is an obtuse angle.

[0015] Preferably, a bearing is slidably disposed in the second elongated hole, and a bearing baffle for axially limiting the bearing is disposed in the second elongated hole, and the connecting shaft passes through the bearing baffle and is connected to the bearing.

[0016] Preferably, the end of the actuating end is provided with a floating bearing, and the floating bearing is connected to the end of the connecting shaft opposite to the bearing.

[0017] Preferably, the mounting plate has a strip-shaped hole on its side wall, and the connecting shaft is vertically slidable within the strip-shaped hole.

[0018] Preferably, the mounting plate is provided with an outer cover plate, which is used to enclose the power mechanism.

[0019] Preferably, the sliding pin is a graphite bushing, and the rotating pin is a rotating pin.

[0020] Preferably, the number of the mounting plate, the power mechanism, and the actuator are all two, and the two mounting plates, the two power mechanisms, and the two actuators are symmetrically arranged about the photovoltaic panel.

[0021] Compared to the aforementioned background technology, this application provides a movable solar photovoltaic panel, which is installed on the outer wall above a window, specifically on the outer wall between two windows. Utilizing a crank-slider mechanism, the photovoltaic panel transitions from a vertically retracted state to a horizontally extended state, with the extended panel positioned along the upper edge of the window. Specifically, this movable solar photovoltaic panel uses an electric cylinder as its power mechanism, providing power to a crank-rocker arm. The rotation of the crank-rocker arm acts on the photovoltaic panel through a rotating pin, and the freedom of movement of the sliding pin is constrained by a first elongated hole, ensuring that the upper part of the photovoltaic panel does not shift vertically during extension, while the lower part of the panel moves away from the outer wall, achieving a shading effect after extension. Furthermore, the extension process can be seen as adjusting the angle of the photovoltaic panel to adapt to different incident angles of sunlight, improving light energy utilization.

[0022] Specifically, the movable solar shading photovoltaic panel includes a photovoltaic panel, a mounting plate, a power mechanism, and an actuator. The photovoltaic panel has sliding pins and rotating pins on its two sides. The mounting plate is located on both sides of the photovoltaic panel, and its side wall has a first elongated hole in which the sliding pins slide vertically. The power mechanism uses an electric cylinder to convert the rotational motion of a servo motor into linear motion, precisely controlling the unfolding angle of the photovoltaic panel and simultaneously positioning it after unfolding. The actuator includes a crank rocker arm and a connecting shaft connecting the crank rocker arm and the actuating end of the electric cylinder. The extension / retraction motion of the electric cylinder acts on the crank rocker arm, which in turn acts on the photovoltaic panel through the rotating pins hinged to the crank rocker arm, thus completing the crank-slider mechanism. This movable solar shading photovoltaic panel, designed in this way, can adjust its angle according to the incident angle of sunlight to enhance the light energy utilization rate of the photovoltaic panel, providing shading while generating photovoltaic power.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] It should be noted that the instruction manual includes... Figure 2In this context, the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the purpose of facilitating and simplifying the description of this application, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] As per the instruction manual Figure 1 As shown, in this embodiment, a movable sunshade panel is provided. It is installed on the outer wall above the window, specifically on the outer wall between two windows, i.e., installed on the inter-window wall. On the building facade, the wall between two windows is the inter-window wall, which is usually the main load-bearing wall. (See attached specification.) Figure 4 and Figure 5 In this system, the movable shading photovoltaic has two states: a retracted state and an extended state. Of course, it also includes the tilted state after adjusting the angle of the photovoltaic panel.

[0038] like Figure 2 As shown, the aforementioned movable solar photovoltaic panel 100 includes a photovoltaic panel 1, a mounting plate 2, a power mechanism 3, and an actuator 4. The photovoltaic panel 1 is a component used to convert light energy into electrical energy. Mounting plates 2 are provided on both sides of the photovoltaic panel 1. The side wall of the mounting plate 2 is provided with a first elongated hole 21 that penetrates through itself and is vertically arranged. Of course, the mounting plate 2 needs to be fixedly installed with the window wall to ensure the stability of the photovoltaic panel 1.

[0039] In addition, the power mechanism 3 adopts an electric cylinder 31, which can convert the rotational motion of the servo motor into linear motion, and has precise speed control, position control, and thrust control, ensuring the accuracy of the power mechanism 3 in motion engineering. It should be noted that in this embodiment, the actuating end of the electric cylinder 31 extends or retracts in the vertical direction.

[0040] For the aforementioned implementing agency 4, such as Figure 2 and Figure 6 As shown, the actuator 4 is mainly used to connect the actuating end of the electric cylinder 31 and the photovoltaic panel 1. It includes a crank rocker arm 41 and a connecting shaft 43 connecting the crank rocker arm 41 and the actuating end. The non-end of the crank rocker arm 41 is rotatably connected to the side wall of the mounting plate 2 through the bearing seat 42. The end of the crank rocker arm 41 is provided with a second elongated hole 44 that passes through itself. The end of the connecting shaft 43 away from the actuating end extends into the second elongated hole 44 and is slidably connected with the second elongated hole 44.

[0041] It should be noted that, as Figure 2 and Figure 3As shown, the photovoltaic panel 1 has sliding pins 11 that pass through the first elongated hole 21 and are slidably disposed therewith on both sides. In addition, the photovoltaic panel 1 also has rotating pins 12 that are hinged to the end of the crank rocker arm 41 away from the second elongated hole 44 on both sides.

[0042] In summary, the movable solar photovoltaic panel 100 of this application is installed on the outer wall above the window, specifically on the outer wall between two windows. Through a crank-slider mechanism, the photovoltaic panel 1 is converted from a vertically retracted state to a horizontally extended state. Figure 4 and Figure 5 As shown, the unfolded photovoltaic panel 1 is located at the upper edge of the window. Specifically, the movable sunshade photovoltaic panel 100 uses an electric cylinder 31 as the power mechanism 3 to provide power to the crank rocker arm 41. The rotation effect of the crank rocker arm 41 acts on the photovoltaic panel 1 through the rotating pin 12, and the freedom of movement of the sliding pin 11 is constrained by the first elongated hole 21, ensuring that the upper end of the photovoltaic panel 1 does not shift in the vertical dimension during the unfolding process. At the same time, the lower end of the photovoltaic panel 1 is away from the outer wall, achieving the sunshade effect after unfolding. In addition, the above unfolding process can be regarded as adjusting the angle of the photovoltaic panel 1 to adapt to different incident angles of sunlight and improve the utilization rate of light energy.

[0043] In summary, the movable solar photovoltaic panel 100 includes a photovoltaic panel 1, a mounting plate 2, a power mechanism 3, and an actuator 4. The photovoltaic panel 1 has sliding pins 11 and rotating pins 12 on its two sides. The mounting plate 2 is located on both sides of the photovoltaic panel 1, and a first elongated hole 21 is provided on the side wall of the mounting plate 2. The sliding pins 11 slide vertically within the first elongated hole 21. The power mechanism 3 uses an electric cylinder 31, which can convert the rotational motion of the servo motor into linear motion, precisely controlling the unfolding angle of the photovoltaic panel 1 and simultaneously positioning the unfolded photovoltaic panel 1. The actuator 4 includes a crank rocker arm 41 and a connecting shaft 43 connecting the crank rocker arm 41 and the actuating end of the electric cylinder 31. Figure 6 and Figure 7 As shown, the extension / retraction motion of the electric cylinder 31 acts on the crank rocker arm 41, and through the rotating pin 12 hinged to the crank rocker arm 41, it acts on the photovoltaic panel 1, thus completing the setting of the crank-slider mechanism. The movable shading photovoltaic panel 100 set in the above manner can adjust its angle according to the incident angle of sunlight to enhance the light energy utilization rate of the photovoltaic panel 1, and can provide shading while generating photovoltaic power.

[0044] Furthermore, such as Figure 6As shown, the extension motion of the actuator pushes the crank rocker arm 41 to rotate around the axis of the bearing seat 42. At this time, the crank rocker arm 41 and the rotating pin 12 will push the lower end of the photovoltaic panel 1 closer to the outer wall in a rotating hinge manner. At the same time, under the principle of the crank-slider mechanism and the limiting sliding of the sliding pin 11 in the first elongated hole 21, the sliding pin 11 will move vertically upward in the first elongated hole 21, thereby driving the upper end of the photovoltaic panel 1 vertically upward, thus completing the retraction action of the photovoltaic panel 1. Similarly, Figure 7 A schematic diagram of the power mechanism 3 and the actuator 4 is provided when the photovoltaic panel 1 is in the unfolded state. At this time, the actuating end of the electric cylinder 31 is retracted, the crank rocker arm 41 drives the lower end of the photovoltaic panel 1 away from the outer wall, and at the same time, the sliding pin 11 moves vertically downward in the first elongated hole 21 to complete the unfolding action of the photovoltaic panel 1.

[0045] Based on the above embodiments, the photovoltaic panel 1 of this application uses a conventional component with a frame, the size of which can be selected according to the actual site conditions; the sliding pin 11 is set at the upper part of the side of the photovoltaic panel 1, or it can be located at the end of the photovoltaic panel 1, as long as it does not affect the sliding of the photovoltaic panel 1 within the first elongated hole 21; the rotating pin 12 is located at the middle of the side of the photovoltaic panel 1, which facilitates pushing or pulling the photovoltaic panel 1 back; of course, there are no strict restrictions on the specific setting positions of the sliding pin 11 and the rotating pin 12, as long as the principle of the crank-slider mechanism can be realized. In addition, the two sliding pins 11 and the two rotating pins 12 located on the two sides of the photovoltaic panel 1 are symmetrically arranged about the photovoltaic panel 1 to ensure the consistency of the movement of the two sides of the photovoltaic panel 1.

[0046] Furthermore, a rotating shaft 47 is provided on the crank rocker arm 41, penetrating the side wall of the mounting plate 2 and rotatably connected to the bearing seat 42. The crank rocker arm 41 is divided into two sections by the rotating shaft 47, and the included angle between the two sections of the crank rocker arm 41 is an obtuse angle. The obtuse angle opens upwards, meaning that in order for the photovoltaic panel 1 to be in a vertical position when retracted, the crank rocker arm 41 needs to be set at a certain angle and cannot be a straight-edge structure. Of course, the specific angle of the obtuse angle is not specifically limited here, as long as it ensures that the photovoltaic panel 1 can be retracted and unfolded.

[0047] To facilitate the sliding and rotation of the connecting shaft 43 within the second elongated hole 44, a bearing 45 is slidably installed within the second elongated hole 44 and limited by a bearing baffle 46 on the second elongated hole 44. At the same time, the connecting shaft 43 passes through the bearing baffle 46 and is connected to the bearing 45, ensuring that when the electric cylinder 31 pushes the connecting shaft to move up and down, the connecting shaft 43 has sufficient sliding space to accommodate the rotation of the crank rocker arm 41.

[0048] In addition, a floating bearing 32 is provided at the actuating end of the electric cylinder 31. The floating bearing 32 is connected to the end of the connecting shaft 43 away from the bearing 45. The floating bearing 32 enables the connecting shaft 43 to adapt to multi-angle changes, enhances the toughness of the connecting shaft 43 at this point, and ensures that the crank rocker arm 41 can rotate stably. At the same time, a strip hole 22 is provided on the side wall of the mounting plate 2. The connecting shaft 43 slides vertically within the strip hole 22 to meet the limit positions of the vertical movement of the connecting shaft 43.

[0049] To improve the overall safety and aesthetics of the movable sunshade panel 100, such as Figure 9 As shown, an outer cover plate 5 is provided on the mounting plate 2, which can enclose the power mechanism 3. In addition, the sliding pin 11 is made of graphite bushing to enhance its wear resistance; the rotating pin 12 is made of pin. Of course, the sliding pin 11 and the rotating pin 12 can be set according to actual needs, which will not be described in detail here.

[0050] Based on the above embodiments, the number of mounting plate 2, power mechanism 3, and actuator 4 are all two, and the two mounting plates 2, two power mechanisms 3, and two actuators 4 are symmetrically arranged about the photovoltaic panel 1 to improve the consistency of movement on both sides of the photovoltaic panel 1, thereby improving the overall stability of the photovoltaic panel 1.

[0051] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0052] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
