[0029] The present invention will be described in detail with reference to the accompanying drawings. What is described here is only a preferred embodiment of the present invention, and those skilled in the art can think of other ways to implement the present invention based on the preferred embodiment, and other ways also fall within the scope of the present invention.

[0030] Example

[0031] Reference Figure 1-Figure 4 The present embodiment provides a photovoltaic module frame, including a top support frame 110, a middle connection frame 120 and a bottom plane frame 130, one end of the middle connection frame 120 is connected to the top support frame 110, and the other end is connected to the bottom plane frame 130; the top support frame 110 includes a side support 111 and a bottom support 112, the side support 111 and the bottom support 112 are connected to form a glue filling groove 113, the bottom of the glue filling groove 113 is an arc structure or a straight line structure that gradually descends from the bottom support 112 to the side support 111. The gradually descending arc structure or straight line structure makes the bottom of the glue filling groove 113 have a height difference, and the colloid can flow from top to bottom under the action of gravity, and the colloid automatically fills the lower part of the glue filling groove 113, which is conducive to increasing the fluidity of the colloid, so that the glue filling groove 113 can be filled with colloid, and sufficient colloid is conducive to the fixation of the photovoltaic panel 200.

[0032] On the other hand, the bottom of the arc-shaped glue-filling groove 113 is conducive to increasing the structural strength of the top support frame 110 and improving the bearing capacity of the top support frame 110 on the photovoltaic panel 200. The bottom support 112 is used to abut the bottom of the photovoltaic panel 200, and the side support 111 is used to abut the side of the photovoltaic panel 200. The bottom support 112 and the side support 111 provide support for the photovoltaic panel 200 in two directions, which can improve the stability of the photovoltaic panel 200 installed on the frame.

[0033] As mentioned above, the bottom of the glue filling groove 113 can be an arc-shaped structure or a straight-line structure. When the bottom of the glue filling groove 113 is a straight-line structure, some reinforcement structures can be provided on the bottom of the glue filling groove 113 for the sake of strength of the glue filling groove 113. Figure 3 and Figure 4 As shown, a plurality of ribs 115 are arranged at intervals at the bottom of the glue filling groove 113, and the ribs 115 are arranged along the length direction of the top support frame 110. The ribs 115 can increase the structural rigidity of the bottom of the glue filling groove 113 to prevent it from twisting and deforming.

[0034] Furthermore, the top of the rib 115 is chamfered on both sides, and the two sides of the rib 115 are inclined so that the top of the rib 115 is smaller than the bottom. The rib 115 forms a structure that is small at the top and large at the bottom, and the chamfering of the top can reduce the resistance to the flow of the colloid, improve the fluidity of the colloid in the glue filling groove 113, facilitate the colloid to fill the glue filling groove 113, and increase the contact between the colloid and the photovoltaic panel 200. In addition, in addition to optimizing the structure of the rib 115 itself, the fluidity of the colloid in the glue filling groove 113 can also be increased by optimizing the spacing between two adjacent ribs 115. In this embodiment, the spacing between two adjacent ribs 115 is greater than the maximum width of the longitudinal section of the rib 115, so that the adhesive contact area between the colloid and the photovoltaic panel 200 can be increased while ensuring the fluidity of the colloid, thereby improving the bonding strength.

[0035] When filling the glue filling groove 113, it is necessary to consider the overflow of the glue to prevent the overflowed glue from contaminating the light-receiving surface of the photovoltaic panel 200. Figure 1-Figure 4 As shown, a rubber stop rib 114 is provided on the inner side of the side support 111, and the rubber stop rib 114 extends in the direction of the photovoltaic panel 200, and there is a gap between the end of the rubber stop rib 114 and the photovoltaic panel 200. The rubber stop rib 114 makes an additional groove between the side support 111 and the glue filling groove 113, and the shape of the groove can accommodate a part of the colloid, so as to prevent the colloid from overflowing to the surface of the photovoltaic panel 200 when the filling amount of the colloid is large, thereby preventing the light absorption efficiency of the photovoltaic panel 200 from decreasing. The extension length and angle of the rubber stop rib 114 can be designed according to actual needs, and are not unique. As shown in the figure and the figure, different rubber stop ribs 114 bring different structures of the glue filling groove 113.

[0036] In this embodiment, Figure 1-Figure 4 As shown, the top of the side support 111 is tilted toward the photovoltaic panel 200, and the side support 111 has a certain curvature as a whole, which can improve the side impact resistance of the frame. The top of the side support 111 is flush with the light-receiving surface of the photovoltaic panel 200, which can protect the side of the photovoltaic panel 200 while avoiding blocking the light-receiving surface of the photovoltaic panel 200, thereby improving the photoelectric conversion efficiency of the photovoltaic panel 200.

[0037] Furthermore, in this embodiment, referring to Figure 1-Figure 4, a plurality of reinforcing ribs 122 are arranged on the inner side of one side wall of the middle connecting frame 120, and the side wall between two adjacent reinforcing ribs 122 is in an arc-shaped structure. A plurality of reinforcing ribs 123 are arranged on the inner side of the side wall of the middle connecting frame 120 relative to the reinforcing rib 122, and the reinforcing ribs 123 are arranged along the length direction of the middle connecting frame 120, and the side wall between two adjacent reinforcing ribs 123 is in an arc-shaped structure. Both the reinforcing ribs 122 and the reinforcing ribs 123 can increase the structural strength of the inner side of the middle connecting frame 120, and improve the structural rigidity and deformation resistance. Setting the side wall between the reinforcing ribs 122 or the reinforcing ribs 123 into an arc-shaped structure can, on the one hand, improve the compression resistance of the inner side wall, and on the other hand, reduce the wall thickness of the side wall, which is beneficial to the lightweight design of the overall frame.

[0038] It should be noted that the top support frame 110, the middle connection frame 120 and the bottom plane frame 130 are an integrated structure. The integrated structure can make the photovoltaic module frame have good structural rigidity, and the integrated structure can be processed at one time by a mold, thereby reducing manufacturing errors and manufacturing costs.

[0039] Another aspect of the present application also provides a photovoltaic module frame installation structure, including a pressing block 300 and the above-mentioned photovoltaic module frame, the outer side of the photovoltaic module frame is provided with a snap-in groove 124, one end of the pressing block 300 extends into the snap-in groove 124 and snaps into the snap-in groove 124. One end of the pressing block 300 is connected to the outer side of the photovoltaic module frame through the snap-in groove 124 to achieve the installation of the photovoltaic module frame, avoid direct contact between the pressing block 300 and the light-receiving surface of the photovoltaic panel 200, and eliminate the obstruction of the light-receiving surface of the photovoltaic panel 200. Please refer to Figure 5 and Figure 6 The snap-in groove 124 is arranged on the outside of the photovoltaic component frame in an embedded or externally extended structural form.
