Description

[0002] In existing outdoor multi-functional folding photovoltaic panel technologies, users often need to adjust multiple components multiple times when unfolding the photovoltaic panel. This design not only increases the complexity of operation but may also lead to operational errors, thus affecting the user experience and efficiency. For example, some existing products may require adjusting the angle and position of each photovoltaic panel separately, or additional tools and steps are needed to fix or unlock certain components. These cumbersome operations are not only time-consuming but may also adversely affect the structure and lifespan of the photovoltaic panel.

[0003] Chinese Utility Model Patent Application No. 202323212441.1 discloses a foldable photovoltaic panel, including a base, a central pole, and an umbrella tray. One end of the central pole is detachably connected to the base. The umbrella tray includes a connecting plate and multiple photovoltaic panels. The connecting plate is detachably connected to the other end of the central pole. One end of each photovoltaic panel is movably connected to the connecting plate. The photovoltaic panels are hinged to each other, and the photovoltaic panels can be unfolded or folded around the circumference of the connecting plate. Although this device can be folded to the maximum extent to reduce space occupation and facilitate transportation and storage, after unfolding, the photovoltaic panels need to be supported by multiple support rods and sliding sleeves in the locking assembly, which is too complicated to operate. Moreover, the device has a special shape after folding, making it inconvenient to store and carry.

[0004] Therefore, it is necessary to propose a multifunctional outdoor photovoltaic folding panel to solve the above problems. Summary of the Invention

[0026] Example 1 Please see Figures 1 to 3An outdoor multifunctional photovoltaic folding panel includes a main frame 1. The main frame 1 includes an upper cover plate 2, a lower fixing frame 3, an internal threaded ring 5, a mounting cylinder 6, and multiple support columns 4. The upper cover plate 2 and the lower fixing frame 3 are both regular polygons. The multiple support columns 4 are fixedly installed between the upper cover plate 2 and the lower fixing frame 3. The internal threaded ring 5 is fixedly connected to the center of the lower fixing frame 3. The mounting cylinder 6 is fixedly connected between the internal threaded ring 5 and the upper cover plate 2. A rotating shaft 17 is rotatably connected between the multiple support columns 4. A photovoltaic panel assembly 16 is fixedly connected to the outside of the rotating shaft 17. The photovoltaic panel assembly 16 includes a main... A photovoltaic panel 18 is fitted with an opening and closing mechanism 19 on the outside of the mounting cylinder 6. The opening and closing mechanism 19 is used to control the opening and closing of multiple photovoltaic panel modules 16. The opening and closing mechanism 19 includes an adjusting collar 22 that is slidably connected to the outside of the mounting cylinder 6. The top of the adjusting collar 22 is annularly hinged with multiple linkage rods 23. The number of linkage rods 23 is the same as that of the main photovoltaic panel 18. The ends of the linkage rods 23 are hinged to the middle of the main photovoltaic panel 18. A guide slide 43 is vertically opened on the surface of the mounting cylinder 6. A guide block is fixedly connected to the inside of the adjusting collar 22. The guide block is slidably connected to the guide slide 43.

[0027] In this embodiment, the photovoltaic mechanism is configured as a regular prism after folding, such as... Figure 1 The hexagonal prism shown is supported by an upper cover plate 2, a lower fixed frame 3, and multiple support columns 4. It can be used as a stool, concealing multiple photovoltaic panel modules 16 within the sides of the prism, thus reducing the size of the photovoltaic mechanism. To unfold, simply push the adjusting collar 22; the collar 22 slides upwards along the mounting cylinder 6. The adjusting collar 22, via the linkage rod 23, simultaneously rotates multiple main photovoltaic panels 18 along the rotating shaft 17, thereby achieving unfolding. Figure 2 As shown; with this setup, multiple main photovoltaic panels 18 can be deployed simultaneously in just one step, greatly reducing the difficulty of operation and making it particularly suitable for outdoor use.

[0028] Example 2 Please see Figure 2 , Figure 4 and Figure 6This embodiment is a further optimization based on embodiment 1. Specifically, the photovoltaic panel assembly 16 also includes a first photovoltaic panel 32 and a second photovoltaic panel 34. The first photovoltaic panel 32 and the second photovoltaic panel 34 are right-angled triangles. The right-angled side of the first photovoltaic panel 32 is rotatably connected to the bottom of one side of the main photovoltaic panel 18 through a hinge 35. An extension plate 33 is fixedly connected to the bottom of the other side of the main photovoltaic panel 18. The height of the extension plate 33 is greater than the thickness of the first photovoltaic panel 32. The right-angled side of the second photovoltaic panel 34 is rotatably connected to the bottom of the extension plate 33 through a hinge 35. The extension plate 33 is designed to ensure that the first photovoltaic panel 32 can be smoothly folded and attached to the back of the main photovoltaic panel 18. Subsequently, the second photovoltaic panel 34 can be stacked orderly under the first photovoltaic panel 32, thus realizing an alternating folding layout and effectively avoiding the spatial interference problem that may occur between the two photovoltaic panels. A reset torsion spring is also sleeved on the hinge 35. The reset torsion spring is used to drive the first photovoltaic panel 32 and the second photovoltaic panel 34 to rotate inward.

[0029] Please see Figure 6 The top of the main photovoltaic panel 18 is provided with an installation channel 36. The installation channel 36 is provided with a main fixing rope 37. One end of the main fixing rope 37 is fixedly connected to two auxiliary fixing ropes 38. The two auxiliary fixing ropes 38 extend from both sides of the main photovoltaic panel 18 and are fixedly connected to the first auxiliary photovoltaic panel 32 and the second auxiliary photovoltaic panel 34 respectively. The other end of the main fixing rope 37 extends from the middle of the lower surface of the main photovoltaic panel 18 and is fixedly connected to the middle of the installation cylinder 6. The installation channel 36 is symmetrically rotatably connected with guide pulleys 39. The two auxiliary fixing ropes 38 pass around the two guide pulleys 39 respectively.

[0030] In this embodiment, by setting a first auxiliary photovoltaic panel 32 and a second auxiliary photovoltaic panel 34 on both sides of the main photovoltaic panel 18, the total area of ​​the photovoltaic panel after unfolding is increased, thus improving the power generation efficiency. Moreover, when the adjusting collar 22 in embodiment 1 drives multiple main photovoltaic panels 18 to unfold simultaneously via the linkage rod 23, the lower surface of the main photovoltaic panel 18 moves away from the mounting cylinder 6, and the main fixing rope 37 between the main photovoltaic panel 18 and the mounting cylinder 6 is relatively lengthened, indirectly stretching the main fixing rope 37. The main fixing rope 37 then pulls the two auxiliary fixing ropes 38, which in turn pull the first auxiliary photovoltaic panel 32 and the second auxiliary photovoltaic panel 34 on both sides of the main photovoltaic panel 18, thereby unfolding the first auxiliary photovoltaic panel 32 and the second auxiliary photovoltaic panel 34. Furthermore, under the action of the return torsion spring on the hinge 35, the photovoltaic panel slides downward for adjustment when being stored. The adjusting collar 22, through the linkage rod 23, drives multiple main photovoltaic panels 18 to retract inward simultaneously. The lower surface of the main photovoltaic panel 18 approaches the mounting cylinder 6, and the main fixing rope 37 between the main photovoltaic panel 18 and the mounting cylinder 6 is relatively shortened. At this time, the two auxiliary photovoltaic panels are no longer under tension and rotate inward and fold under the action of the return torsion spring. The first auxiliary photovoltaic panel 32 and the second auxiliary photovoltaic panel 34 are folded on the lower surface of the main photovoltaic panel 18, so that the main photovoltaic panel 18, the first auxiliary photovoltaic panel 32 and the second auxiliary photovoltaic panel 34 are arranged sequentially from the outside to the inside. This design utilizes the retraction and stretching action of the rope to unfold the two auxiliary photovoltaic panels at the same time as unfolding the main photovoltaic panel 18. This not only increases the area of ​​the photovoltaic panels, but also eliminates unnecessary operation steps, relying entirely on the movement of the main photovoltaic panel 18 itself, thus improving the practicality of the device.

[0031] Example 3 Please see Figure 3 , Figure 5 , Figure 7 and Figure 8 This embodiment is a further optimization based on embodiment 2. Specifically, the opening and closing mechanism 19 is provided with a locking mechanism 20. Limiting holes 21 are provided in the middle and bottom outer sides of the mounting cylinder 6. The locking mechanism 20 includes a mounting groove 24 provided at the bottom of the adjusting collar 22 and a rotating cover 28 fitted at the bottom of the adjusting collar 22. A pin 26 is fixedly connected inside the mounting groove 24 by a compression spring 25. The pin 26 is engaged with the limiting hole 21. An adjusting post 27 is fixedly connected to the bottom of the pin 26. An arc-shaped adjusting slide 31 is provided at the bottom of the rotating cover 28. The adjusting post 27 is located in the adjusting slide 31. A slider 30 is fixedly connected to the inner side of the top of the rotating cover 28. An annular groove 29 is provided on the outer side of the adjusting collar 22. The slider 30 is slidably connected to the annular groove 29.

[0032] In this embodiment, by setting a locking mechanism 20 and two sets of limiting holes 21 in the middle and bottom of the mounting cylinder 6, when unfolding the photovoltaic panel, one only needs to pinch the rotating cover 28 through the lower fixing frame 3 and rotate it. The rotating cover 28 squeezes the adjusting column 27 through the adjusting slide 31, thereby pulling the pin 26 away from the limiting hole 21 at the bottom of the mounting cylinder 6. Then, the adjusting collar 22 is pushed upward. When the pin 26 is aligned with the limiting hole 21 in the middle of the mounting cylinder 6, under the tension of the compression spring 25, the pin 26 is inserted into the limiting hole 21, completing the limiting fixation. This not only limits the opening and closing mechanism 19 when folding and unfolding, but also makes adjustment convenient.

[0033] Example 4 Please see Figure 7 and Figure 9 This embodiment is a further optimization based on embodiment 1. Specifically, a removable lithium battery 7 is provided in the middle of the mounting cylinder 6, a charging panel 13 is fixedly connected to the top of the mounting cylinder 6, a control circuit board 12 is electrically connected to the bottom of the charging panel 13, a power male connector 11 is electrically connected to the bottom of the control circuit board 12, both the power male connector 11 and the control circuit board 12 are fixedly connected to the mounting cylinder 6, a power female connector 10 is electrically connected to the top of the lithium battery 7, an external threaded cover 8 is detachably installed inside the internal threaded ring 5, and a slotted rib 9 is fixedly connected to the outer surface of the external threaded cover 8; a mounting opening 14 is provided in the middle of the upper cover plate 2, a sliding cover 15 is slidably connected inside the mounting opening 14, the sliding cover 15 is used to protect the charging panel 13, the charging panel 13 is integrated into the internal space of the mounting opening 14, and its surface is equipped with a USB standard interface, a DC power output interface and a digital display screen, and the main light The photovoltaic panel 18, the first photovoltaic panel 32, and the second photovoltaic panel 34 form an electrical circuit with the central control circuit board 12 through multi-core wires. The control circuit board 12 adopts a DC-DC converter topology and has bidirectional power transmission capability. Under illumination, its built-in MPPT (maximum power point tracking) algorithm can convert the DC power generated by the photovoltaic array through the Boost boost circuit and then perform constant current and voltage limiting charging for the rechargeable lithium battery 7 through the DC-DC isolation module. The control circuit board 12 drives the lithium battery 7 to provide a 5V / 12V adjustable DC output to the charging panel through the bidirectional DC / DC converter. An operation slot 40 is opened on the bottom shell of the lithium battery 7, and an operation board 41 is fixedly connected in the operation slot 40. Pulling the operation board 41 can pull out the lithium battery 7. A handle 42 is fixedly connected to the top of the top cover 2. By setting the handle 42, it is convenient to lift and carry the photovoltaic folding panel device.

[0034] In this embodiment, by opening the sliding cover 15 inside the mounting port 14, the data cable of a mobile device, such as a mobile phone, can be connected to the USB charging port on the charging panel 13 for charging. By setting the lithium battery 7 inside the mounting cylinder 6, the effect of energy storage is achieved, and the remaining power of the lithium battery 7 can be observed through the display screen. Furthermore, by setting the inner threaded ring 5 and the outer threaded cover 8, the outer threaded cover 8 can be removed by turning the flat rib 9. Then, by pulling the operating plate 41 inside the operating slot 40, the power female connector 10 at the top of the lithium battery 7 is separated from the power male connector 11, and the lithium battery 7 can be pulled out, thus realizing the installation and replacement of the lithium battery 7.

[0035] In summary: The main frame 1 of this invention adopts a regular polygonal design, consisting of an upper cover plate 2, a lower fixed frame 3, and a support column 4. When folded, it can be used as a stool, combining functionality and portability. The photovoltaic panel assembly 16 is hidden on the side of the prism, significantly reducing the size of the device, making it suitable for outdoor scenarios. By adjusting the collar 22 and sliding it along the mounting cylinder 6, the linkage rod 23 synchronously drives multiple main photovoltaic panels 18 to rotate and unfold around the rotating shaft 17. Only one step is needed to complete the unfolding of all photovoltaic panels, reducing the difficulty of use. The design is suitable for complex outdoor environments, taking into account both aesthetics and practicality. The addition of a first secondary photovoltaic panel 32 and a second secondary photovoltaic panel 34 expands the total area of ​​the photovoltaic panels. Automatic unfolding / folding is achieved through the linkage of a hinge 35 and a reset torsion spring, without the need for additional operation steps. The main fixing rope 37 and the secondary fixing rope 38 work together with the guide pulley 39 to drive the secondary photovoltaic panels to unfold or fold using the tension and contraction characteristics of the ropes, thereby enhancing mechanical stability. After folding, the secondary photovoltaic panels are tightly attached to the lower surface of the main photovoltaic panel 18, forming a hierarchical arrangement, which reduces the space occupied and improves the structural compactness. The locking mechanism 20 achieves the limiting and fixing of the opening and closing mechanism 19 by engaging the pin 26 with the limiting hole 21, ensuring the stability of the unfolded or folded state and preventing misoperation; the rotating cover 28 and the adjusting slide 31 work together to squeeze the adjusting column 27, quickly releasing the pin 26, and combined with the automatic rebound function of the compression spring 25, simplifying the locking process; It has a built-in removable lithium battery 7 and a charging panel 13, supports solar storage and USB and DC interfaces for charging multiple devices, and monitors the power level in real time through the display screen to meet outdoor power needs; the lithium battery 7 can be quickly installed and removed through the operation slot 40 and the operation board 41 for easy maintenance and replacement.
