[0030] In order to make the purpose, technical solution and advantages of the specific implementation of the present invention more clear, the specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings. Here, the schematic specific implementation of the present invention and its description are used to explain the present invention, but are not intended to limit the present invention.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4A and Figure 4BAs shown, the present invention provides a flexible photovoltaic system for realizing flexible connection between rigid photovoltaic components while ensuring system strength. The flexible photovoltaic system includes a plurality of photovoltaic components 100 and a plurality of frames 200 matching the photovoltaic components 100, wherein:

[0032] The plurality of frames 200 are arranged in sequence, and the plurality of photovoltaic modules 100 are embedded in each of the frames 200;

[0033] Both ends of the frame 200 have a connecting portion 210 and a wiring port 220 that are arranged opposite to the adjacent frame 200: each two adjacent frames 200 are movably connected through the connecting portion 210 and can be rotated to change the relative position; the wiring port 220 of each two adjacent frames 200 is movably connected to form a wiring groove 300, and the connecting wires 110 of each photovoltaic component 100 pass through the wiring groove 300 and are electrically connected to an adjacent photovoltaic component 100 in turn.

[0034] In a specific implementation, the connection parts 210 at both ends of each frame 200 may be arranged in a variety of embodiments. Figure 1 , Figure 2 As shown, in order to simplify the connection structure while ensuring the reliability of the connection, two adjacent frames 200 can be connected through two points, that is, two connecting parts 210 can be provided at both ends of each frame 200, wherein: the two connecting parts 210 are respectively provided on both sides of the frame 200, and further, in order to give the connecting line 110 movement space when the frame rotates and avoid bumping the connecting line 110, the connecting part 210 can protrude outside the main body along the arrangement direction of the frame 200, thereby increasing the distance between the two adjacent frames to protect the connecting line 110.

[0035] In a specific implementation, there may be multiple implementation schemes for the connection between the connection parts 210. Figure 1 , Figure 2 As shown, in order to ensure the connection strength and improve the working reliability of the system, the two connecting parts 210 arranged opposite to each other can be hingedly connected by a hinge shaft 400, wherein: the side walls of each connecting part 210 can be provided with an axial hole, and intersect with the top of the connecting part 210 arranged opposite to each other to align the axial hole; the hinge shaft 400 can then pass through each of the axial holes to hingely connect the two connecting parts 210.

[0036] In a specific implementation, there are many implementation schemes for the connection port 220. For example, Figure 3 , Figure 4A and Figure 4BAs shown, in order to prevent the wiring port 220 from being disposed on the outside of the frame 200 and damaging the connecting wire 110, the wiring port 220 can be disposed between the two connecting portions 210; further, in order to effectively protect the connecting wire 110, the wiring port 220 can all protrude out of the main body along the arrangement direction of the frame 200, that is, to form a wiring groove 300 of equal length to the gap between the frame 200, thereby preventing the wiring harness from being exposed.

[0037] In a specific implementation, there are multiple implementation schemes for setting the movable connection mode of the connection port 220. For example, Figure 3 , Figure 4A and Figure 4B As shown, the two wiring ports 220 in each wiring slot 300 can be the same as the connecting portion 210, that is, they are also hingedly connected through the hinge shaft 400, wherein: the two slot walls of each wiring port 220 can be provided with an axial hole, and intersect with the top of the wiring port 220 arranged oppositely to align the axial hole, and the hinge can be an axis passing through each axial hole to hingely connect the two wiring ports 220.

[0038] In specific implementation, Figure 3 , Figure 4A and Figure 4B As shown, in order to enhance the connection stability of the wiring slot 300, avoid the wiring harness from being exposed during operation, and further ensure the overall strength of the system, the wiring slot 300 may also be provided with a flexible reinforcement component 310. The flexible reinforcement component 310 can enhance stability while not restricting the rotation of the wiring slot 300. Furthermore, there may be a variety of implementation schemes for the selection of the flexible reinforcement component 310. For example, since the composite hinge structure has excellent flexibility without losing stability, the flexible reinforcement component 310 may be a composite hinge reinforcement component. Further, as Figure 5A , Figure 5B and Figure 5C As shown, the composite hinge reinforcement component may include a first hinge rod 311, a second hinge rod 312 and a hinge plate 313, wherein: the two connection ports 220 are each provided with a first hinge rod 311, and the first hinge rod 311 can move in an arc track 221 opposite to the connection port 220; the second hinge rod 312 is arranged in parallel between the two first hinge rods 311, and is movably connected to the two first hinge rods 311 through the hinge plate 313.

[0039] In a specific implementation, in order to further protect the connecting wire 110, a connecting wire 110 protection member may be provided. There are many implementation schemes for providing the connecting wire 110 protection member, for example, Figure 3 , Figure 4A and Figure 4BAs shown, the flexible photovoltaic system may further include a wire hose 320 , which is disposed inside the wiring slot 300 and covers the outside of the connecting line 110 .

[0040] In a specific implementation, there are multiple implementation schemes for selecting the wire hose 320. For example, since the plastic wire hose has the advantages of light weight, corrosion resistance and high temperature resistance, the wire hose 320 can be a plastic wire hose. For another example, since the corrugated tube has excellent bending property and working reliability, the wire hose 320 can also be a corrugated wire hose.

[0041] In summary, the flexible photovoltaic system provided by the present invention comprises a plurality of frames arranged in sequence and photovoltaic modules 100 arranged inside the frames, and each frame 200 has a connection portion 210 and a wiring port 220 arranged opposite to the adjacent frame 200 at both ends: each adjacent frame 200 is movably connected through the connection portion 210, and can be rotated and moved with the connection point as the axis to change the relative position; the wiring ports 220 of each adjacent frame 200 are movably connected to form a wiring groove 300, and the connection wires 110 of each photovoltaic module 100 are all passed through the wiring groove 300 to be electrically connected with the adjacent photovoltaic module 100, so that each photovoltaic module 100 is connected in series. The flexible photovoltaic module 100 system aims at the defects of the existing photovoltaic modules 100 having few flexible varieties and high demand for flexible applications, and creatively uses the flexible connection structure to realize the flexible installation of conventional rigid crystalline silicon modules; at the same time, the design of the flexible wiring groove 300 also effectively guarantees the reliability and structural strength of the circuit connection.

[0042] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
