[0002] Solar power generation devices, also known as solar cells or photovoltaic cells, can directly convert solar energy into electrical energy. The principle of power generation is based on the photovoltaic effect of semiconductor PN junction. As a strategic emerging energy industry, solar photovoltaics have become a clean energy necessary for human development due to its safety, low pollution and renewability.

[0003] The core component of solar cells is the photovoltaic full-screen module. After completing the production and packaging and warehousing processes, the photovoltaic full-screen module needs to be transported to a designated location for assembly.

In order to protect the full-screen modules, aluminum frames are usually used to wrap the laminates. During the use of aluminum frames, the following problems are prone to occur: 1. There are process tolerances in the processing and manufacturing of aluminum profile frames and glass. Extreme tolerances will affect the appearance of the product; 2. After the aluminum profile frame of the full-screen module is extruded and assembled, the four corners are prone to deformation during assembly and transportation, thereby damaging the laminates.

[0030] Example

[0031] Reference Figure 1-Figure 3 , this embodiment provides a photovoltaic full-screen assembly, including a screen body, a protective frame 4 installed around the screen body, a laminate 3 and a corner protection structure. The screen body is mainly composed of solar photovoltaic panels, and the two ends of the protective frame 4 have installation slots. Among them, the corner protection structure includes a corner guard 1 and a corner code 2, and the corner guard 1 is installed at the corner of the corner code 2; a supporting surface 101 is provided at one end of the corner guard 1, and the supporting surface 101 is used to support a corner of the laminate 3; a flange structure 102 is provided on the supporting surface 101, and the flange structure 102 covers the two sides of a corner of the laminate 3. The flange structure 102 of the supporting surface 101 covers the two sides of a corner of the laminate 3, which can prevent the four corners of the full-screen photovoltaic assembly from colliding during transportation and damaging the laminate 3, thereby protecting the four corners of the photovoltaic assembly.

[0032] In order to improve the protection of a corner of the laminate 3, the flange structure 102 is folded in the normal direction of the supporting surface 101 and folded toward the upper side of the supporting surface 101, and the edge of the flange structure 102 exceeds the plane of the laminate 3. Moreover, the edge of the flange structure 102 is bent or gathered inward to cover both sides of each corner of the laminate 3, greatly improving the protection of the laminate 3. In addition, as Figure 1 and Figure 2 As shown, the inner side of the flange structure 102 is provided with a glue overflow groove 103, and the glue overflow groove 103 can leave overflow space for the flange structure 102 during glue sealing to prevent the glue from overflowing and contaminating the full-screen component.

[0033] In this embodiment, in addition to considering the protective effect of the corner guard 1 on the four corners of the photovoltaic module, it is also necessary to consider the structural stability of the corner guard 1 itself. Figure 1 As shown, a receiving cavity 106 is provided on the side of the corner guard 1 facing the corner bracket 2, and the receiving cavity 106 receives the corner of the corner bracket 2. The top wall of the receiving cavity 106 is the supporting surface 101, the bottom wall and the top wall of the receiving cavity 106 cover the upper and lower ends of the corner bracket 2, and the two side walls of the receiving cavity 106 cover the corner of the corner bracket 2, further increasing the structural protection of the corner of the photovoltaic module.

[0034] In order to further increase the stability of the connection between the corner guard 1 and the corner bracket 2, the cavity wall of the accommodating cavity 106 is provided with an anti-slip piece, and the outer side of the corner bracket 2 is provided with an anti-slip groove, and the anti-slip piece cooperates with the anti-slip groove to keep the corner guard 1 and the corner bracket 2 fixed. Figure 1 As shown, the anti-slip member includes a first buckle 104 and a second buckle 105, and a plurality of second buckles 105 are provided and distributed on both sides of the first buckle 104. The anti-slip groove includes a first buckle position 201 and a second buckle position 202, and the first buckle position 201 is buckled with the first buckle 104, and the second buckle position 202 is buckled with the second buckle 105. The first buckle position 201 is located at the corner vertex of the corner code 2.

[0035] In this embodiment, Figure 2 and Figure 3 As shown, the side walls of the corner code 2 are inserted into the installation slots at both ends of the protective frame 4 and connect the adjacent protective frames 4. The four corner codes 2 connect the four protective frames 4 to form a frame, which surrounds the full screen body. Each corner of the laminate 3 is positioned on the supporting surface 101 of the corner guard 1. The laminate 3 covers the screen body composed of solar photovoltaic panels. The supporting surface 101 cooperates with the flanging structure 102 to protect each corner of the laminate 3. An anti-slip structure 204 is provided on the corner code 2. The anti-slip structure 204 contacts the inner wall of the protective frame 4, which can increase the friction between the corner code 2 and the protective frame 4 and prevent the corner code 2 from falling off from the protective frame 4. The anti-slip structure 204 includes multiple anti-slip grooves. The inclination direction of the anti-slip grooves is opposite to the insertion direction of the corner code 2 to the protective frame 4, which improves the anti-retreat ability of the corner code 2 and further improves the connection tightness between the corner code 2 and the protective frame 4. In addition, a plurality of weight-reducing holes 203 are provided on the side wall of the corner bracket 2. The weight-reducing holes 203 are through holes or blind holes, which can reduce the weight of the corner bracket 2 while ensuring the structural strength of the corner bracket 2, thereby reducing the weight of the entire photovoltaic module and improving the energy density of the photovoltaic module.
