Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Example:

[0032] Reference Figure 1-5 The device includes a folding bag 1 and a right photovoltaic panel 6. The folding bag 1 includes a middle folding strap 2, a left folding strap 4 rotatably connected to the left end of the middle folding strap 2, and a right folding strap 3 rotatably connected to the right end of the middle folding strap 2. The rear end of the right photovoltaic panel 6 has a right mounting groove 19. An upper support frame 21 is rotatably connected to the top of the inside of the right mounting groove 19, and a lower support frame 22 is rotatably connected to the bottom of the inside of the right mounting groove 19. A plug 17 is fixedly connected to the rear end of the middle folding strap 2, near the right folding strap 3. A left mounting groove 24 is opened on the rear surface of the left folding strap 4. A tension strap 25 is fixedly connected to the surface of the left folding strap 4, located at the rear end of the left mounting groove 24. A second plug 26 is fixedly connected to the top of the tension strap 25. A locking interface 23 is opened inside the lower support frame 22. The surface of the folding bag 1 is covered with PVC coated fabric. The interior of the folding bag 1 consists of the left folding strap 4, the middle folding strap 2, and the right folding strap 3 from left to right. The middle folding strap 2, right folding strap 3, and left folding strap 4 can be folded and flipped. Photovoltaic panels are installed on the front surfaces of each strap for photovoltaic power generation. When folding, first rotate the right folding strap 3 towards the front surface of the middle folding strap 2, so that its surface covers the front of the middle folding strap 2. Then rotate the left folding strap 4 towards the rear surface of the right folding strap 3, so that its surface covers the rear of the right folding strap 3. After folding the right folding strap 3, the plug 17 on the right side of the rear of the middle folding strap 2 is exposed. After folding the left folding strap 4, the tension strap 25 and the second plug 26 at the rear of the left folding strap 4 are exposed. Pulling the tension strap 25 inserts the second plug 26 into the plug 17, completing the folding process. When unfolding the folding bag 1, the upper and lower support plates in the right mounting slot 19 at the rear of the right folding strap 3 can be removed. The structure of the left mounting slot 24 at the rear of the left folding strap 4 is the same as that of the right mounting slot 19. After removing the support plates from the left folding strap 4 and the right folding strap 3, rotate the lower support frame 22 and place it on the ground or structural layer. Then rotate the upper support frame 21 and insert it into the card interface 23, so that the upper support frame 21, the lower support frame 22 and the folding bag 1 form a triangular structure, thus completing the unfolding and installation.

[0033] Reference Figure 2 and Figure 4A rotating shaft 20 is rotatably connected inside the right mounting slot 19, and an upper support frame 21 is fixedly connected to the surface of the rotating shaft 20. The upper support frame 21 can be rotated through the rotating shaft 20 to unfold and retract the support frame.

[0034] Reference Figure 2 and Figure 3 The plug 17 has a side insertion hole 18 on its inner side. The side end of the second plug 26 is fixedly connected to a spring seat 27, and the top of the spring seat 27 is fixedly connected to a side locking block 28. When folding the folding bag 1, the bracket in the left mounting slot 24 can be stored and bound by the tension strap 25. When unfolding the folding bag 1, the side locking block 28 at the side insertion hole 18 can be pressed, and the spring seat 27 at the lower end of the side locking block 28 can be pressed into the plug 17. Then, the second plug 26 can be pulled out by the tension of the tension strap 25.

[0035] Reference Figure 1 and Figure 5 A central photovoltaic panel 14 is installed on the front surface of the central folding belt 2, a right photovoltaic panel 6 is installed on the front surface of the right folding belt 3, and a left photovoltaic panel 5 is installed on the front surface of the left folding belt 4. The left photovoltaic panel 5, the central photovoltaic panel 14, and the right photovoltaic panel 6 are used for photovoltaic power generation, and an inner slot 7 is provided in the middle of the left photovoltaic panel 5.

[0036] Reference Figure 1 and Figure 2 The front end surface of the left folding belt 4 is provided with an inner slot 7. When the folding package 1 is folded, the front end of the left folding belt 4 will cover the rear end surface of the right folding belt 3. At this time, the inner slot 7 will cover the right mounting slot 19 on the surface of the right folding belt 3, which can prevent the bracket from causing wear to the left photovoltaic panel 5.

[0037] Reference Figure 1 and Figure 5 A left support rod 8 is fixedly connected inside the folding bag 1, located between the middle folding strap 2 and the left folding strap 4. A right support rod 9 is fixedly connected inside the folding bag 1, located between the middle folding strap 2 and the right folding strap 3. The left support rod 8 and the right support rod 9 act as the internal skeleton of the folding bag 1, adding weight to the overall device and making it less likely to tip over when blown by the wind during unfolding, thus improving the stability of the device.

[0038] Reference Figure 1 and Figure 5 Inside the folding case 1, at the rear end of the left support rod 8 and right support rod 9, a cable routing groove 16 is provided. A conductor wire 15 is inserted into the cable routing groove 16, and a power converter socket 10 is fixedly connected to the top of the conductor wire 15 at the rear end of the middle folding strip 2. The cable routing groove 16 is located inside the folding case 1 at the rear end of the left support rod 8, and its interior is used for installing circuit wiring; folding does not affect the wiring. The power converter socket 10 can convert voltage, providing a power interface that can be directly used for everyday tools.

[0039] Reference Figure 1 The converter power adapter 10 has a USB interface 12 at its top, a switch 11 at its top, and an indicator light 13 at its top, located to the right of the USB interface 12. The USB interface 12 is used to connect electrical devices, and the switch 11 is used to control the output switch. The USB interface 12 is used to display the current output status.

[0040] The implementation principle of a foldable photovoltaic power generation device according to this application is as follows: When folding, the right folding strap 3 can be rotated towards the front end surface of the middle folding strap 2, so that the surface of the right folding strap 3 covers the front end of the middle folding strap 2. Then, the left folding strap 4 can be rotated towards the rear end surface of the right folding strap 3, so that the left folding strap 4 covers the rear end of the right folding strap 3. After the right folding strap 3 is folded, the plug 17 on the right side of the rear end of the middle folding strap 2 can be exposed. After the left folding strap 4 is folded, the tension strap 25 and the second plug 26 at the rear end of the left folding strap 4 can be exposed. At this time, pulling the tension strap 25 will insert the second plug 26 into the interior of the plug 17, thus completing the folding. When unfolding the folding bag 1, the upper and lower support plates in the right mounting groove 19 at the rear end of the right folding strap 3 can be removed. The structure of the left mounting groove 24 at the rear end of the left folding strap 4 is the same as that of the right mounting groove 19. After removing the support plates from the left folding strap 4 and the right folding strap 3, rotate the lower support frame 22 and place it on the ground or structural layer. Then, rotate the upper support frame 21 and insert it into the card interface 23, so that the upper support frame 21, the lower support frame 22, and the folding bag 1 form a triangular structure, completing the unfolding and installation. When folding the folding bag 1, the support bracket in the left mounting slot 24 can be stored and restrained using the tension strap 25. When unfolding the folding bag 1, the side locking block 28 at the side insertion hole 18 can be pressed, and the spring seat 27 at the lower end of the side locking block 28 can be used to press it into the plug 17. Then, the second plug 26 can be pulled out by the tension of the tension strap 25. When the folding bag 1 is folded, the front end of the left folding strap 4 will cover the rear end surface of the right folding strap 3. At this time, the inner card slot 7 will cover the right mounting slot 19 on the surface of the right folding strap 3, which can prevent the support bracket from abrading the left photovoltaic panel 5. This device is designed with three folding straps, which can store the support device when stored, occupying little space and making it convenient for outdoor sports. It can be quickly unfolded and installed during use, facilitating rapid connection to electrical appliances. The device is highly stable, has a wide range of applications, and is easy to carry.
