Therefore, different numbers of small-sized photovoltaic modules are adapted to meet the appropriate power requirements.

[0004] To meet the requirements for electricity use, multiple small-sized photovoltaic modules need to be connected in an array. Therefore, the structure needs to consider how to make these small-sized photovoltaic modules easy to carry and store after they are connected. Summary of the Invention

[0009] Furthermore, the adapter plate is parallel to the base plate of the U-shaped component, and a connecting plate is fixedly connected between the upper end of the base plate and the upper end of the adapter plate.

[0010] Furthermore, threaded holes for fixing hinges are respectively provided at both ends of the adapter plate.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] like Figure 1 , Figure 2The diagram shows a quick connection structure for small-sized photovoltaic modules, which has connecting blocks 2 used in pairs between adjacent photovoltaic modules 1 on the left and right or top and bottom. The connecting block 2 includes a U-shaped component 20, an adapter plate 21, and a connecting plate 22. The U-shaped component 20 includes a short side plate 202, a long side plate 203, and a bottom plate 204. The short side plate 202 and the long side plate 203 are arranged in parallel. The bottom plate 204 is fixed to the bottom of the short side plate 202 and the long side plate 203, and the bottom plate 204 protrudes from the outer side of the short side plate 202 to form a stepped surface. The short side plate 202, the long side plate 203, and the bottom plate 204 form a slot 201 structure.

[0023] The adapter plate 21 and the base plate 204 of the U-shaped part 20 are arranged in parallel. The connecting plate 22 is fixed between the upper end of the base plate 204 and the upper end of the adapter plate 21. A hinge 3 is provided between the adapter plates 21. Threaded holes 210 for fixing the hinge 3 are respectively opened at both ends of the adapter plate 21.

[0024] The side of the photovoltaic module 1 is fitted into the slot 201 of the U-shaped part 20, forming a mortise and tenon structure connection. The left and right or top and bottom adjacent photovoltaic modules 1 can be flipped and folded through the hinge 3.

[0025] See Figure 5 , Figure 6 As shown, when the rotation center of hinge 3 is located at the top, the short side plate 202 is bonded and fixed to the upper side of photovoltaic module 1, and the long side plate 203 is bonded and fixed to the lower side of photovoltaic module 1. At this time, the connecting block 2 forms a forward installation state. When the rotation center of hinge 3 is located at the bottom, the short side plate 202 is bonded and fixed to the lower side of photovoltaic module 1, and the long side plate 203 is bonded and fixed to the upper side of photovoltaic module 1. At this time, the connecting block 2 forms a reverse installation state.

[0026] Figure 3 This is a structural diagram connecting four photovoltaic modules 1. For ease of description, the four photovoltaic modules 1 are represented by A, B, C, and D respectively. The connecting block 2 between module A and module B is installed facing forward, with the rotation center of the hinge 3 located at the top; the connecting block 2 between module B and module C is installed in reverse, with the rotation center of the hinge 3 located at the bottom; the connecting block 2 between module C and module D is installed facing forward, with the rotation center of the hinge 3 located at the top. When folding and storing, first fold module A upwards onto the top surface of module B, then fold the folded modules A and B downwards onto the bottom surface of module C, and finally fold the folded modules A, B, and C upwards onto the top surface of module D.

[0027] Figure 4This is a structural diagram of six photovoltaic modules 1 connected together. For ease of description, the six photovoltaic modules 1 are represented by abcdefg. The connecting block 2 between module a and module b is installed facing forward, with the rotation center of hinge 3 located at the top. The connecting block 2 between module b and module c is installed in reverse, with the rotation center of hinge 3 located at the bottom. The connecting block 2 between module c and module d is installed facing forward, with the rotation center of hinge 3 located at the top. The connecting block 2 between module d and module e is installed in reverse, with the rotation center of hinge 3 located at the bottom. The connecting block 2 between module e and module f is installed facing forward, with the rotation center of hinge 3 located at the top. When folding for storage, the modules are folded sequentially from a to f: upward-downward-upward-downward-upward.

[0028] The above operation enables quick installation and storage of small-sized photovoltaic modules 1, which can be stored in a small space, solving the current problems of crystalline silicon modules being difficult to carry and inconvenient to use.

[0029] In addition, if the photovoltaic module 1 is rectangular, when connecting, since the long frame part of the module is relatively long, two pairs of smaller connecting blocks 2 can be used for connection. When connecting the short frame of the module, a single pair of larger connecting blocks 2 can be used for connection.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
