Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. 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.

[0037] Firstly, the basic structure, such as Figure 1As shown, an outward-folding frame for a photovoltaic module includes a top edge plate 101, a first side edge plate 102, a first bottom edge plate 103, a second side edge plate 104, a second bottom edge plate 105, and a third side edge plate 106.

[0038] The top edge plate 101, the first side plate 102, and the first bottom edge plate 103 form a first space with an opening on one side, and the first space is used to insert the edge of the photovoltaic panel of the photovoltaic module.

[0039] The first bottom plate 103, the second side plate 104, the second bottom plate 105, and the third side plate 106 form a second space, which is used to place corner brackets.

[0040] Before the corner brackets of the photovoltaic module are installed, the third side plate 106 and the first bottom plate 103 are disconnected to allow the size of the second space to change elastically. After the corner brackets are installed, the third side plate 106 is welded to the first side plate 102 or the first bottom plate 103 or the first side plate 102 and the first bottom plate 103 to fix the size of the second space.

[0041] In conventional photovoltaic (PV) module frames, the second space for inserting corner brackets is typically a fixed size. In existing installation methods, this second space is manufactured slightly larger than the corner bracket size to facilitate installation. However, this results in a larger gap between the corner bracket and the frame, affecting the stability of the connection between the two frames. In this invention, before installing the corner brackets, the third side plate 106 and the first bottom plate 103 are disconnected, allowing the size of the second space to change flexibly, thus facilitating corner bracket installation. After the corner brackets are installed, the third side plate 106 is welded to the first side plate 102 or the first bottom plate 103, or the first side plate 102 and the first bottom plate 103, to fix the size of the second space, thereby improving the frame's stability.

[0042] Specifically, the preferred example is, for instance... Figure 1 As shown, based on the aforementioned outward-folding frame structure, the following structure is included: the top edge plate 101, the first side edge plate 102, the first bottom edge plate 103, the second side edge plate 104, the second bottom edge plate 105, and the third side edge plate 106 are connected sequentially; the top edge plate 101, the first side edge plate 102, the first bottom edge plate 103, the second side edge plate 104, the second bottom edge plate 105, and the third side edge plate 106 are formed by multiple bending of the same plate. The top edge plate 101, the first side edge plate 102, the first bottom edge plate 103, the second side edge plate 104, the second bottom edge plate 105, and the third side edge plate 106 are made from the same plate, a manufacturing method with lower costs than pultrusion of aluminum profiles, and the plate material can be thinner, such as a plate with a thickness of 1mm.

[0043] Specifically, preferred example two, such as Figure 2 , Figure 3 , Figure 4 As shown, based on the outward-folding frame of the above-mentioned basic structure, the following structure is included: the front end of the top edge plate 101 is bent to form an end edge plate 107, and the upper surface of the end edge plate 107 is attached to the lower surface of the top edge plate 101; the end edge plate 107, the top edge plate 101, the first side edge plate 102, the first bottom edge plate 103, the second side edge plate 104, the second bottom edge plate 105, and the third side edge plate 106 are connected in sequence; the end edge plate 107, the top edge plate 101, the first side edge plate 102, the first bottom edge plate 103, the second side edge plate 104, the second bottom edge plate 105, and the third side edge plate 106 are formed by bending the same plate multiple times. The end plate 107, top plate 101, first side plate 102, first bottom plate 103, second side plate 104, second bottom plate 105, and third side plate 106 are made from the same sheet body. This manufacturing method is less expensive than pultrusion of aluminum profiles, and the sheet material can be thinner, such as 1mm thick. The end plate 107 is used to reinforce the strength of the top plate 101 to prevent it from collapsing.

[0044] Specifically, the preferred example is three, such as... Figure 5 As shown, based on the outward-folding frame of the aforementioned basic structure, the following structure is included: an inclined guide plate 108 is connected between the first bottom edge plate 103 and the second side edge plate 104, the guide plate 108 being inclined downwards; the top edge plate 101, the first side edge plate 102, the first bottom edge plate 103, the guide plate 108, the second side edge plate 104, the second bottom edge plate 105, and the third side edge plate 106 are connected sequentially; the top edge plate 101, the first side edge plate 102, the first bottom edge plate 103, the guide plate 108, the second side edge plate 104, the second bottom edge plate 105, and the third side edge plate 106 are formed by multiple bending of the same plate. The inclined guide plate 108 facilitates guiding the photovoltaic panels of the photovoltaic module into the first space.

[0045] Specifically, preferred example four, such as Figure 6 , Figure 8 , Figure 9As shown, based on the aforementioned outward-folding frame structure, the following structure is included: the front end of the top edge plate 101 is bent to form an end edge plate 107, the upper surface of the end edge plate 107 is attached to the lower surface of the top edge plate 101; an inclined guide plate 108 is connected between the first bottom edge plate 103 and the second side edge plate 104, the guide plate 108 being inclined downwards; the end edge plate 107, top edge plate 101, first side edge plate 102, first bottom edge plate 103, guide plate 108, second side edge plate 104, second bottom edge plate 105, and third side edge plate 106 are connected sequentially; the end edge plate 107, top edge plate 101, first side edge plate 102, first bottom edge plate 103, guide plate 108, second side edge plate 104, second bottom edge plate 105, and third side edge plate 106 are formed by multiple bending of the same plate. The inclined guide plate 108 facilitates guiding the photovoltaic panels of the photovoltaic module into the first space. The end plate 107 is used to enhance the strength of the top plate 101 so that the top plate 101 is not easy to collapse.

[0046] Specifically, preferred example five, such as Figure 7 As shown, the front end of the third side plate 106 is bent to form the second end plate 109. After the corner bracket is installed, the second end plate 109 is laser welded to the first bottom plate 103, thereby improving the stability of the frame.

[0047] Specifically, in one optional embodiment, a portion of the first bottom edge plate 103 is recessed downwards to form a pit. In this invention, the bottom edge plates and side plates are not limited to being straight plates.

[0048] Specifically, in one optional implementation, based on the outward-folding frame of any one of the above basic structures to the four preferred examples, the following structure is included: the height of the second space is greater than the height of the first space.

[0049] Secondly, a photovoltaic module, including corner brackets, such as... Figure 10As shown, the corner code includes a first corner code base plate 201 and a second corner code base plate 202. The first corner code base plate 201 has a first corner code side plate 203 and a second corner code side plate 204 on both sides.

The second corner code base plate 202, the third corner code side plate 205, and the fourth corner code side plate 206 are placed in the second space of the second frame. The first frame and the second frame respectively adopt the basic structure or the frame of the photovoltaic module described in Preferred Example 1 or Preferred Example 2. Specifically, in one optional embodiment, the first corner code base plate 201 and the second corner code base plate 202 are perpendicular to each other; the first corner code side plate 203 and the third corner code side plate 205 are fitted together; and the second corner code side plate 204 and the fourth corner code side plate 206 are fitted together. The outer edges of the first corner code side plate 203, the second corner code side plate 204, the third corner code side plate 205, and the fourth corner code side plate 206 are provided with serrations. The corner codes connect the first frame and the second frame, making them less prone to detachment.

[0050] Secondly, another type of photovoltaic module includes corner brackets, such as... Figure 11 As shown, the corner code includes a first corner code base plate 201 and a second corner code base plate 202. The first corner code base plate 201 has a first corner code side plate 203 and a second corner code side plate 204 on both sides. The second corner code base plate 202 has a third corner code side plate 205 and a fourth corner code side plate 206 on both sides.

Specifically, in one optional embodiment, the first corner code base plate 201 and the second corner code base plate 202 are perpendicular to each other; the first corner code side plate 203 and the third corner code side plate 205 are fitted together; and the second corner code side plate 204 and the fourth corner code side plate 206 are fitted together. The outer edges of the first guide side plate, the second corner code side plate 204, the second guide side plate, and the fourth corner code side plate 206 are provided with serrations. The corner codes connect the first frame and the second frame, preventing them from easily coming apart. The first guide side plate or the second guide side plate corresponds to the guide plate 108 in the first frame or the second frame.
