[0023] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0024] like Figure 1 and 2 As shown, the portable photovoltaic box includes two identical boxes, a left box 1 and a right box 2, connected by at least two hinges 11. Both boxes are equipped with identical photovoltaic panel assemblies 3, each consisting of a foldable upper photovoltaic panel 31 and a lower photovoltaic panel 32. The upper photovoltaic panel 31 and the lower photovoltaic panel 32 are rotatably connected by a connector 6, allowing them to be folded and unfolded for easy storage. After folding, the two photovoltaic panel assemblies 3 can be placed in the left box 1 and the right box 2. The bottom of the lower photovoltaic panel 32 is hinged to the bottom of the box via a photovoltaic panel hinge 14, and the top of the upper photovoltaic panel 31 is connected to the bottom of the box via a left support rod 33 and a right support rod 34. The open sides of the two boxes are connected by several fasteners. In this embodiment, both the upper photovoltaic panel 31 and the lower photovoltaic panel 32 are reinforced. Specifically, an aluminum alloy or stainless steel reinforcing frame is provided on the outside of the upper photovoltaic panel 31 and the lower photovoltaic panel 32 to improve their strength.

[0025] The left support rod 33 and the right support rod 34 have the same structure. The left support rod 33 includes an upper rod body 331, a lower rod body 332, and a connecting sleeve 333. Both the upper rod body 331 and the lower rod body 332 are threadedly connected to the connecting sleeve 333. The upper rod body 331 and the lower rod body 332 have the same diameter. The top of the upper rod body 331 is provided with an upper mounting hole, and a T-shaped upper rotating shaft 334 is provided in the upper mounting hole. The small end of the upper rotating shaft 334 is fixedly connected to the upper photovoltaic panel 31, and the large end of the upper rotating shaft 334 limits its movement. A countersunk through hole that mates with the upper rotating shaft 334 can also be provided on the upper rotating shaft 334 to better facilitate its installation. The top of the upper rod body 331 is rotatably connected to the upper photovoltaic panel 31 through the upper rotating shaft 334, and the bottom of the upper rod body 331 is fixedly connected to the housing through the lower hinge end 12.

[0026] like Figure 3 As shown, the bottom of the upper rod 331 is provided with an upper threaded section 3311, and the top of the lower rod 332 is provided with a lower threaded section 322. The inner wall of the connecting sleeve 333 is provided with an internal thread that mates with the upper threaded section 3311 and the lower threaded section 322. Specifically, after the upper photovoltaic panel 31 and the lower photovoltaic panel 32 are flattened, the connecting sleeve 333 is first installed on the upper rod 331, making the upper rod 331 and the lower rod 332 coaxially aligned. Then, by rotating the connecting sleeve 333, the rotating connecting sleeve 333 is threadedly connected with the upper threaded section 3311 and the lower threaded section 322, thereby fixing the upper rod 331 and the lower rod 332 together. After the upper rod 331 and the lower rod 332 are connected as a whole, the flattened upper photovoltaic panel 31 and the lower photovoltaic panel 32 are supported and fixed. After the upper photovoltaic panel 31 and the lower photovoltaic panel 32 are flattened, they form a 60-degree angle with the ground.

[0027] like Figure 4 As shown, the connector 6 has two connecting holes, and a T-shaped central pivot 7 is installed in each of the two connecting holes. The small end of one central pivot 7 is fixedly connected to the upper photovoltaic panel 31, and the small end of the other central pivot 7 is fixedly connected to the lower photovoltaic panel 32. The large end of the central pivot 7 limits the connector 6, so that the upper photovoltaic panel 31 and the lower photovoltaic panel 32 can be folded and rotated through the connector 6 and the central pivot 7.

[0028] The upper photovoltaic panel 31 is provided with an upper limit block 8 that cooperates with each connector 6, and the lower photovoltaic panel 32 is provided with a lower limit block 9 that cooperates with each connector 6. The upper limit block 8 and the lower limit block 9 are respectively provided on the back side of the upper photovoltaic panel 31 and the lower photovoltaic panel 32, and the upper limit block 8 and the lower limit block 9 limit the upper photovoltaic panel 31 and the lower photovoltaic panel 32 after they are flattened. Each upper limit block 8 is provided with a locking thread hole, and a locking screw 101 is provided in the locking thread hole. The connector 6 is provided with a locking blind that cooperates with the small end of the locking screw 101. When the upper photovoltaic panel 31 and the lower photovoltaic panel 32 are flattened, the lower end face of the upper photovoltaic panel 31 is in contact with the upper end face of the lower photovoltaic panel 32. At this time, the upper photovoltaic panel 31 can overcome the downward force at the middle hinge by the friction of the end face. In order to further prevent the hinge from moving downward, the locking screw 101 can be screwed into the connector 6 to lock the connector 6, thereby fixing the hinge of the upper photovoltaic panel 31 and the lower photovoltaic panel 32.

[0029] Both boxes are equipped with U-shaped handles 13. When the two boxes are closed, the two handles 13 can be combined into one, making it easy to move the boxes.

[0030] Each compartment is equipped with several elastic straps, each with a Velcro front side and a Velcro back side. These elastic straps work together to secure each folded photovoltaic panel, preventing it from shifting within the compartment.

[0031] Working principle and process: When unfolding for use, open the left box 1 and the right box 2 and place them flat on the ground. Then, pull out one of the photovoltaic panel components 3 to unfold. After the upper photovoltaic panel 31 and the lower photovoltaic panel 32 are pulled out and flattened, they form a 60-degree angle with the ground. Then, make the upper rod 331 and the lower rod 332 coaxial. Then, by rotating the connecting sleeve 333, the bottom of the upper rod 331 and the top of the lower rod 332 are threadedly connected, so that the upper rod 331 and the lower rod 332 are connected as a whole. After 332 is connected, it forms an integrated support rod, which supports the flattened upper photovoltaic panel 31 and lower photovoltaic panel 32. Similarly, the left support rod 33 and right support rod 34 of each photovoltaic panel assembly 3 are installed in the same way to complete the installation and fixation of each photovoltaic panel assembly 3. Similarly, the photovoltaic panel assembly 3 in the two boxes can be unfolded and fixed. After each photovoltaic panel assembly 3 is flattened, the connecting piece 6 can be locked with the locking screw 101 to fix the hinge of the upper photovoltaic panel 31 and lower photovoltaic panel 32. When storing, first unscrew the locking screw 101 of the connector 6 to lock the hinge between the upper photovoltaic panel 31 and the lower photovoltaic panel 32. Then rotate the connecting sleeve 333 upward to disconnect the threaded connection between the connecting sleeve 333 and the upper rod 331 and the lower rod 332. This operation can be performed on the left support rod 33 and the right support rod 34 of each photovoltaic panel assembly 3, so that the photovoltaic panel assembly 3 can be folded. Specifically, the upper photovoltaic panel 31 can be folded over the lower photovoltaic panel 32 first, and the upper rod 331 can be folded over along with the upper photovoltaic panel 31. The lower rod 332 can be directly stored in the box. Then fold the upper photovoltaic panel 31 over the lower photovoltaic panel 32, and then fold the upper photovoltaic panel 31 and the lower photovoltaic panel 32 together and put them into the box. Finally, use elastic straps to tie the joints of the folded photovoltaic panel assembly. Similarly, complete the storage of the photovoltaic panel assembly 3 corresponding to the two boxes. Finally, after the left box 1 and the right box 2 are attached, they can be closed with the buckle.
