[0034] Please see Figures 1-3 The photovoltaic device 100 of this application includes a housing 10 and a photovoltaic module 20. The housing 10 is openable and closable. The photovoltaic module 20 includes a plurality of photovoltaic devices 21, each photovoltaic device 21 being rotatably connected to another photovoltaic device 21. The photovoltaic module 20 is capable of being in a folded state and an unfolded state. When folded, the photovoltaic module 20 is housed within the housing 10, and when the housing 10 is opened, the photovoltaic module 20 is unfolded outside the housing 10. The photovoltaic device 21 includes a photovoltaic panel 211 and a frame 212. The frame 212 surrounds the edge of the photovoltaic panel 211. When the photovoltaic device 100 is in the unfolded state, the frames 212 of adjacent photovoltaic devices 21 abut against each other, so that adjacent photovoltaic devices 21 are maintained at a predetermined angle α.

[0035] In the photovoltaic device 100 of this embodiment, the photovoltaic module 20 can be housed within the housing 10 when folded, making it easier to transport the photovoltaic device 100 via the housing 10. Furthermore, the photovoltaic module 20 can be unfolded outside the housing 10 when it is opened, facilitating normal operation of the photovoltaic device 100 to convert solar energy into electrical energy. Additionally, the frames 212 of adjacent photovoltaic devices 21 abut against each other, maintaining a predetermined angle α between adjacent photovoltaic devices 21. This ensures the photovoltaic module 20 remains in a stable state, increases the light-receiving area of ​​the photovoltaic device 21, and improves the power generation capacity of the photovoltaic device 100.

[0036] Specifically, the housing 10 is a component used to house the photovoltaic module 20. When the photovoltaic module 20 is folded and housed in the housing 10, the photovoltaic module 20 can move along with the housing 10, thus making the photovoltaic device 100 easy to transport.

[0037] The number of photovoltaic devices 21 can be 2, 4, 5, 6, or 8, etc. The photovoltaic device 21 is generally plate-shaped. For example... Figure 5 and Figure 6 As shown, the photovoltaic device 21 has a long edge 2121 and a short edge 2122 that is substantially perpendicular to the long edge 2121. Multiple photovoltaic devices 21 can be detachably connected end to end, for example, multiple photovoltaic devices 21 can be detachably connected end to end along the width direction of the photovoltaic device 21, which facilitates the assembly and disassembly of the photovoltaic device 100 and makes the photovoltaic device 100 easy to use.

[0038] Because multiple photovoltaic devices 21 are rotatably connected, the photovoltaic module 20 can be in a folded state and an unfolded state. When the photovoltaic module 20 is in the folded state, multiple photovoltaic modules 20 are stacked, such as... Figure 1 As shown. When the photovoltaic module 20 is in the deployed state, a predetermined angle is formed between two adjacent photovoltaic devices 21, such as... Figure 3 As shown. Exemplarily, when the photovoltaic module 20 is in the unfolded state, two adjacent photovoltaic devices 21 are maintained at a predetermined angle. In this way, the photovoltaic module 20 is convenient to store and transport when folded, and when the photovoltaic module 20 is in the unfolded state, the angle between two adjacent photovoltaic devices 21 is limited to a predetermined angle, so that the state of the photovoltaic module 20 remains stable, the light-receiving area of ​​the photovoltaic device 21 is increased, which is beneficial for the photovoltaic module 20 to convert solar energy into electrical energy.

[0039] In one example, the predetermined angle α is, for example, 120°-150°, such as 120°, 125°, 130°, 140°, or 150°. This results in a larger unfolded area for the photovoltaic device 1000, which is beneficial for the photovoltaic device 1000 to convert solar energy into electrical energy.

[0040] It is understood that in some other embodiments, the predetermined angle α is, for example, 50°-170°, such as 50°, 60° or 70°.

[0041] The adjacent photovoltaic devices 21 are set at an angle relative to the bearing surface. Without reducing the power generation, the photovoltaic equipment 100 can save space. On the other hand, when there are obstructions such as leaves on the photovoltaic devices 21, the leaves or other obstructions can slide off the surface of the photovoltaic devices 21, avoiding partial shading of the photovoltaic devices 21 and thus reducing the power generation.

[0042] Please see Figure 1 and Figure 2 In some embodiments, the housing 10 includes a first portion 11 and a second portion 12, which are rotatably connected to allow the housing 10 to be opened and closed. This rotatable connection makes it easier to open and close the housing 10. In one example, the first portion 11 and the second portion 12 can be connected by a hinge or other connecting device, allowing them to rotate relative to each other.

[0043] The first part 11 and the second part 12 can be shaped like a cuboid with an opening on one side. When the first part 11 and the second part 12 are closed, they can together form a space to accommodate the photovoltaic module 20.

[0044] Please see Figures 1-3 In some embodiments, the first part 11 includes a first body 111 and a first side plate 112 rotatably connected to the first body 111, the first side plate 112 and the first body 111 being able to form a first receiving space 113;

[0045] The second part 12 includes a second main body 121 and a second side plate 122 rotatably connected to the second main body 121. The second side plate 122 and the first main body 111 can form a second accommodating space 123.

[0046] The first main body 111 and the second main body 121 are rotatably connected. The photovoltaic module 20 is housed in the first accommodating space 113 and / or the second accommodating space 123. When the first main body 111 and the second main body 121 are rotated to open the housing 10, the photovoltaic module 20 can unfold outward from the side corresponding to the first side plate 112 and / or the second side plate 122.

[0047] Thus, the first main body 111 and the second main body 121 are rotatably connected, which makes it easier to open or close the housing 10. In addition, the first side plate 112 and the second side plate 122 can rotate, thereby providing clearance space for the unfolding of the photovoltaic module 20.

[0048] When the folded volume of the photovoltaic module 20 is small, it can be accommodated in either the first accommodating space 113 or the second accommodating space 123; when the folded volume of the photovoltaic module 20 is large, it can be accommodated in both the first accommodating space 113 and the second accommodating space 123. When there are multiple photovoltaic modules 20, some can be accommodated in the first accommodating space 113, while others can be accommodated in the second accommodating space 123.

[0049] Specifically, the first side plate 112 is relative to the base plate of the first part 11, which is the largest plate-like part in terms of area among all the plate-like components of the first part 11. The first part 11 may have multiple side plates, and the side plates and the base plate of the first part 11 can form a first receiving space 113. The first side plate 112 is one of the multiple side plates of the first part 11.

[0050] The second side plate 122 is relative to the base plate of the second part 12, which is the largest plate-type part of the second part 12 in terms of area. The second part 12 may have multiple side plates, and the side plates and the base plate of the second part 12 can form a second receiving space 123. The second side plate 122 is one of the multiple side plates of the second part 12.

[0051] The first side panel 112 and the second side panel 122 can be located on the same side of the housing 10, which gives the photovoltaic module 20 more clearance when it is unfolded, so that the photovoltaic module 20 can be opened smoothly.

[0052] Please see Figures 1-3 In some embodiments, there are two photovoltaic modules 20, one of which can be folded and disposed in the first part 11, and the other of which can be folded and disposed in the second part 12.

[0053] Thus, the two photovoltaic modules 20 can increase the power generation of the photovoltaic device 100 to meet different power generation needs. Specifically, the two photovoltaic modules 20 can be deployed from the same side of the housing 10 or from different sides of the housing 10, thereby adapting to different environments. For example, in the embodiments provided above, when the first side plate 112 and the second side plate 122 can be located on the same side of the housing 10, after the first side plate 112 and the second side plate 122 are deployed, one photovoltaic module 20 can be deployed through the side corresponding to the first side plate 112, and the other photovoltaic module 20 can be deployed through the side corresponding to the second side plate 122.

[0054] Please see Figure 1In some embodiments, the housing 10 is provided with straps 30, which can bind the photovoltaic module 20 when it is folded and placed inside the housing 10. In this way, the straps 30 can further fix the position of the photovoltaic module 20, making the photovoltaic module 20 less swaying during the transportation of the photovoltaic equipment 100 and reducing the probability of damage to the photovoltaic module 20.

[0055] Please see Figure 3 and Figure 4 In some embodiments, the photovoltaic module 20 is in an unfolded state, the photovoltaic device 21 is inclined relative to the bearing surface and forms a lower edge 2101 and a higher edge 2102, and the photovoltaic device 100 includes a connecting shaft 40 and a roller 50 disposed on the connecting shaft 40, the connecting shaft 40 being connected to the lower edge 2101.

[0056] In this way, the photovoltaic device 21 is set at an angle relative to the supporting surface. Without reducing the power generation, it can save the floor space of the photovoltaic equipment 100. On the other hand, when there are obstructions such as leaves on the photovoltaic device 21, the leaves or other obstructions can slide off the surface of the photovoltaic device 21, avoiding the photovoltaic device 21 being partially obstructed and thus reducing the power generation.

[0057] Furthermore, the roller 50 allows the photovoltaic module 20 to slide relative to the bearing surface during the unfolding process, which not only saves effort but also increases the unfolding speed of the photovoltaic module 20.

[0058] Please see Figure 4 In some embodiments, the photovoltaic device 100 includes a grounding stud 60 inserted into the connecting shaft 40 and embedded in the bearing surface. Thus, the grounding stud 60 can improve the stability of the photovoltaic module 20 during use, thereby further improving the power generation efficiency of the photovoltaic module 20.

[0059] Please see Figure 3 and Figure 4 In some embodiments, the photovoltaic device 100 includes a plurality of adapters 70, and each photovoltaic device 21 is rotatably connected to another photovoltaic device 21 via an adapter 70. In this way, the adapter 70 allows two adjacent photovoltaic devices 21 to be rotatably connected.

[0060] Please see Figures 5-6 In some embodiments, the photovoltaic device 21 includes a photovoltaic panel 211 and a frame 212, the frame 212 wrapping around the edge of the photovoltaic panel 211, and the adapter 70 connecting the frames 212 of two adjacent photovoltaic devices 21 to allow the two adjacent photovoltaic devices 21 to be rotatably connected.

[0061] Thus, the frame 212 can provide an installation position for the adapter 70, so that two adjacent photovoltaic devices 21 can be rotatably connected through the adapter 70.

[0062] Please see Figures 5-6 In one embodiment, the photovoltaic panel 211 may include a substrate 2111, solar cells 2112, and a light-transmitting cover plate 2113. The solar cells 2112 are disposed on the substrate 2111, and the light-transmitting cover plate 2113 covers the solar cells 2112. Specifically, the substrate 2111 may be made of materials such as PET, CPC, fiberglass board, or glass. The substrate 2111 may be a rectangular or rounded rectangular sheet. The solar cells 2112 may be fixed to the substrate 2111 by adhesive bonding. The solar cells 2112 are used to convert light energy into solar energy. There may be multiple solar cells 2112, arranged in an array. For example, the row arrangement direction of the solar cells 2112 is the same as the length direction of the substrate 2111, and the column arrangement direction of the solar cells 2112 is the same as the width direction of the substrate 2111.

[0063] The light-transmitting cover 2113 can be made of materials such as PET, CPC, and glass, and the light-transmitting cover 2113 can have the same shape and size as the substrate 2111. The light-transmitting cover 2113 can be bonded to the substrate 2111 or the battery cell 2112 by adhesive bonding.

[0064] Please see Figures 5-6 In one example, the frame 212 includes two long edges 2121 and two short edges 2122, with the two long edges 2121 arranged opposite each other and the two short edges 2122 located between the two long edges 2121. The adapter 70 can connect the long edges 2121 of the frame 212, thereby making the center of gravity of the photovoltaic device 100 lower when folded, and making transportation more convenient.

[0065] Please see Figure 4 For ease of description, in some embodiments, in two adjacent photovoltaic devices 21, the adapter 70 includes a first rotating member 71, a second rotating member 72, and a rotating shaft 73. The first rotating member 71 and the second rotating member 72 are rotatably connected via the rotating shaft 73. The first rotating member 71 is fixed to one of the photovoltaic devices 21, and the second rotating member 72 is fixed to the other photovoltaic device 21. Specifically, the first rotating member 71 is fixed to the frame 212 of one of the photovoltaic devices 21, and the second rotating member 72 is fixed to the frame 212 of the other photovoltaic device 21. In this way, the first rotating member 71 and the second rotating member 72 enable the two adjacent photovoltaic devices 21 to be rotatably connected.
