[0022] like Figure 1-3 As shown, the utility model discloses a foldable photovoltaic module, which includes a box body 1 and a photovoltaic module 2. The photovoltaic module 2 is arranged in the box body 1. The photovoltaic module 2 includes a plurality of photovoltaic panels 21 that are rotatably connected in sequence through scissor parts 3. The photovoltaic panel 21 located at the tail end is rotatably connected to the inner wall of the box body 1. In this embodiment, the box body 1 includes a bottom plate, two side walls, a side plate and an L-shaped plate, wherein the L-shaped plate closes one side and the top of the box body 1, and the side plate and the L-shaped plate are both rotatably connected and detachably connected to the bottom plate. That is, when the photovoltaic module 2 is needed, the side plate and the L-shaped plate can be removed for easy use. The photovoltaic panel 21 includes a solar panel and a frame, and scissor parts 3 are arranged on both sides of the frame, that is, the number of the scissor parts 3 is two, which are respectively located on both sides of the photovoltaic panel 21.

[0023] When the photovoltaic assembly 2 is in the first state, the multiple photovoltaic panels 21 are folded and stored inside the box body 1, that is, in the first state, the photovoltaic panels 21 are stored in the box body 1 in a vertically folded state. When the photovoltaic assembly 2 is in the second state, the multiple photovoltaic panels 21 are unfolded outside the box body 1, that is, in the second state, the multiple photovoltaic panels 21 are unfolded by the scissors 3 and spread horizontally or laid flat at a certain angle.

[0024] Through the rotational connection of the scissor parts 3, the photovoltaic module 2 can flexibly switch between the folded and unfolded states. At the same time, the photovoltaic panel 21 at the tail end is rotationally connected to the box body 1. Through a simple rotation operation, the user can easily change the photovoltaic module 2 from the folded state to the unfolded state. When the photovoltaic module 2 is in the folded state, the photovoltaic panel 21 at the tail end can fit tightly with the inner wall of the box body 1, so the volume and weight of the entire module are effectively controlled, which is easy to carry and transport. This flexibility allows the photovoltaic module 2 to adapt to different usage scenarios and needs, such as rapid deployment in places where temporary power supply is required.

[0025] The photovoltaic module 2 in the present invention is foldable so that the photovoltaic module 2 can be folded into a smaller volume when not in use, making it easier to carry, transport and store.

[0026] In one embodiment, a fixed shaft 11 is fixedly installed in the box body 1 along the horizontal direction, and a rotating block 22 is fixedly installed on the photovoltaic panel 21 at the tail end, and the rotating block 22 is rotatably connected to the fixed shaft 11. The fixed shaft 11 serves as the center point of support and rotation, which ensures the stability and directionality of the photovoltaic panel 21 during folding and unfolding.

[0027] When the photovoltaic assembly 2 needs to be folded, the other photovoltaic panels 21 are folded inwards in sequence through the scissor parts 3 and other structures, and finally the tail photovoltaic panel 21 is also rotated around the fixed axis 11 to a suitable position, so that the entire assembly is compactly stored in the box body 1. When unfolding, the photovoltaic panels 21 are unfolded in sequence through the reverse operation, and the tail photovoltaic panel 21 is also rotated around the fixed axis 11 to a suitable angle to ensure that all photovoltaic panels 21 can be fully exposed to the sun.

[0028] In one embodiment, both sides of the photovoltaic module 2 are provided with symmetrically arranged mounting posts 4, which are fixedly installed on the inner wall of the box body 1 in the longitudinal direction, and both ends of the mounting posts 4 are fixedly installed with threaded posts 5, and the threaded posts 5 are threadedly connected with fixing blocks 6, which are used to fix the photovoltaic module 2 in the first state. In this embodiment, the number of threaded posts 5 and fixing blocks 6 is four, and the fixing blocks 6 can be adjusted according to the actual size and installation requirements of the photovoltaic module 2 to ensure that the photovoltaic module 2 can fit tightly in the box body 1, while preventing it from shaking or falling off during operation.

[0029] In one embodiment, a buffer plate 7 is further included, and the four corners of the buffer plate 7 are detachably connected to the corresponding threaded columns 5 through corresponding fixing blocks 6, and the inner side of the buffer plate 7 contacts the photovoltaic panel 21 located at the head end, that is, the four corners of the buffer plate 7 are provided with through holes corresponding to the four threaded columns 5. That is, when the photovoltaic assembly 2 is in the first state, the through holes on the buffer plate 7 are respectively aligned with the four threaded columns 5 and inserted, and then the corresponding fixing blocks 6 are screwed onto the threaded blocks in turn, so that the inner side of the buffer plate 7 is tightly fitted with the photovoltaic panel 21 located at the head end. The photovoltaic assembly 2 after folding is further prevented from shaking or tilting in the box body 1, thereby enhancing the overall stability of the device.

[0030] In one embodiment, two support assemblies 8 are symmetrically arranged and used to support the photovoltaic assembly 2 in the second state. The support assembly 8 includes a connecting rod 81, a stabilizing seat 82 and a plurality of supporting rods 83. The connecting rod 81 is located between the photovoltaic assembly 2 and the box body 1. The first end of the connecting rod 81 is detachably connected to the box body 1, and the stabilizing seat 82 is detachably connected to the second end of the connecting rod 81. The plurality of supporting rods 83 correspond to the plurality of photovoltaic panels 21 one by one. The supporting rods 83 are detachably connected to the connecting rods 81 in the longitudinal direction and are used to support the corresponding photovoltaic panels 21. In this embodiment, the frame of the photovoltaic panel 21 and the connecting rod 81 are both provided with limiting grooves adapted to the supporting rods 83.

[0031] That is, when the photovoltaic module 2 needs to be unfolded, the connecting rod 81 is first installed on the box body 1, and the stabilizing seat 82 is installed on the connecting rod 81, and the bottom of the stabilizing seat 82 is in contact with the ground. Then the photovoltaic module 2 is unfolded, and after the photovoltaic module 2 is unfolded, the first end of the support rod 83 is inserted into the limit groove on the photovoltaic panel 21, and then the second end of the support rod 83 is inserted into the limit groove on the connecting rod 81, so that the photovoltaic panel 21, the connecting rod 81 and the support rod 83 form a stable triangle to prevent the photovoltaic module 2 from shaking or falling under the influence of external factors such as wind.

[0032] In one embodiment, the connecting rod 81 includes a transition rod 801 and a plurality of adjustment rods 802, the first end of the transition rod 801 is detachably connected to the box body 1, the plurality of adjustment rods 802 are sequentially connected end to end, the adjacent connecting rods 81 are detachably connected, the connecting rod 81 at the tail end is detachably connected to the second end of the transition rod 801, and the connecting rod 81 at the head end is detachably connected to the stabilizing seat 82. In this embodiment, the transition rod 801 is threadedly connected to the threaded column 5, the adjustment rod 802 is clamped to the transition rod 801, the adjustment rods 802 are also clamped to each other, and the adjustment rod 802 at the head end is clamped to the stabilizing seat 82. The number of adjustment rods 802 to be carried can be selected according to the length of the photovoltaic assembly 2 after unfolding, so as to facilitate storage and transportation.

[0033] In one embodiment, the support assembly 8 further includes a plurality of pads 84, which are placed on the ground and respectively located at the bottom of the box body 1 and below the connecting rod 81. Placing the pads 84 below the bottom of the box body 1 helps to increase the distance between the photovoltaic assembly 2 and the ground, adapt to different terrains, and facilitate the installation of the connecting rod 81. Placing the pads 84 below the connecting rod 81, specifically, placing the pads 84 at the connection between two adjacent adjustment rods 802 constituting the connecting rod 81 or at the connection between the adjustment rod 802 and the transition rod 801, further improves the stability of the device in the second state.

[0034] The working principle of this embodiment is as follows:

[0035] In the first state, the photovoltaic assembly 2 is folded inside the box body 1, and the fixing block 6 is threadedly connected to the threaded column 5 to fix the buffer plate 7. The buffer plate 7 fits with the photovoltaic panel 21 at the head end, so that the photovoltaic assembly 2 is not easy to shake and unfold in the box body 1 after folding.

[0036] When the photovoltaic assembly 2 needs to be unfolded, choose whether to place a cushion block 84 at the bottom of the box body 1 according to actual needs, open or remove the side panels and L-shaped panels of the box body 1, unscrew the two fixing blocks 6 at the bottom of the box body 1, install the two transition rods 801 on the threaded columns 5 at the bottom of the box body 1, and then select the multiple adjustment rods 802 required according to actual needs, install the adjustment rods 802 on the transition rods 801, connect the multiple adjustment rods 802 end to end, and install the stabilizing seat 82 on the adjustment rod 802 at the head end. At the same time, place the upper cushion block 84 at the connection between the transition rod 801 and the adjustment rod 802 and the connection between the two adjacent adjustment rods 802. Then unscrew the two fixing blocks 6 at the top of the box body 1 and remove the buffer plate 7. Pull out the photovoltaic panel 21 at the head end, and under the drive of the scissor member 3, the multiple photovoltaic panels 21 are unfolded, and then the photovoltaic panel 21 at the head end is rotated downward, driving the photovoltaic panel 21 at the tail end to rotate around the fixed axis 11 in the box body 1, and the multiple photovoltaic panels 21 are spread out along a certain angle. After that, the first end of the support rod 83 is inserted into the limit groove on the photovoltaic panel 21, and then the second end of the support rod 83 is inserted into the limit groove on the connecting rod 81, so that the photovoltaic panel 21, the connecting rod 81 and the support rod 83 form a stable triangle.
