Specifically, as shown in fig. 1 and 2, the second connecting section 20 is connected to one end of the first connecting section 10, one end of the third connecting section 30 is connected to the other end of the first connecting section 10, the second connecting section 20 is parallel to the third connecting section 30 and is located on the same side of the first connecting section 10, the fourth connecting section 40 is connected to the other end of the third connecting section 30, the fourth connecting section 40 and the first connecting section 10 are respectively located on both sides of the third connecting section 30 in the thickness direction, the fifth connecting section 50 is connected to the other end of the fourth connecting section 40, the fifth connecting section 50 and the third connecting section 30 are located on the same side of the fourth connecting section 40, the sixth connecting section 60 is connected to the other end of the fifth connecting section 50, the sixth connecting section 60 extends toward the third connecting section 30, and the free end of the sixth connecting section 60 has a first bending section 61, and the first bending section 61 is bent from the side of the sixth connecting section 60 far from the fourth connecting section 40 to the side of the sixth connecting section 60 adjacent to the fourth connecting section 40.

According to the utility model discloses frame 100, through set up first bending section 61 on sixth linkage segment 60, and first bending section 61 is kept away from one side of fourth linkage segment 40 from sixth linkage segment 60 and is buckled towards one side of fourth linkage segment 40, can avoid frame 100 to appear in the condition of the free end fish tail arm of the in-process sixth linkage segment 60 of transport or installation to the formation of first bending section 61 can increase the security that frame 100 used. And the structural strength and the fatigue resistance of the frame 100 can be improved, and the fatigue test of the straight load at the weak part of the frame 100 can be avoided, so that the service life of the frame 100 can be prolonged.

In some embodiments, as shown in fig. 1 and 2, the first bend section 61 extends toward the fifth connecting section 50. For example, the first bending section 61 is parallel to the sixth connecting section 60, and the first bending section 61 can realize the complete bending of the first bending section 61, i.e. the rotation angle is 180 °, towards the fifth connecting section 50 by the free end of the Rao Di sixth connecting section 60. Alternatively, the free end of the sixth connecting section 60 of the first bending section 61 Rao Di is bent toward the fifth connecting section 50 by an angle smaller than 180 °. From this, first bending section 61 extends towards fifth linkage segment 50, can effectively avoid the unexpected injury that the free end of sixth linkage segment 60 probably caused, and first bending section 61's simple structure can effectively reduce the cost of frame 100, increases the security of frame 100 simultaneously.

In some embodiments, the included angle between the first bending section 61 and the sixth connecting section 60 is α, and α satisfies: alpha is more than or equal to 0 degree and less than or equal to 90 degrees. For example, in the example of fig. 1, α =0 °, the first bending section 61 has a better scratch-proof effect, the frame 100 has a higher safety, and the risk of scratching the sixth connecting section 60 can be effectively avoided. Alternatively, in the example of fig. 2, α =45 °, the first bent segment 61 is bent toward the fifth connecting segment 50. If α is greater than 90 °, that is, the first bending section 61 and the sixth connecting section 60 are arranged at an obtuse angle, the possibility that the first bending section 61 scratches the arm still exists. Therefore, the range of the included angle between the first bending section 61 and the sixth connecting section 60 is limited, so that the free end of the first bending section 61 is arranged close to the sixth connecting section 60, the use safety of the frame 100 is improved, and the injury of the free end of the first bending section 61 to a user is further avoided.

Meanwhile, as the frame 100 is matched with the laminated part, and the glue layer is filled in the gap between the laminated part and the frame 100, the inclined section 70 can improve the glue overflow condition of the photovoltaic module.

In some embodiments, referring to fig. 1 and 2, an end of the second connecting segment 20 away from the first connecting segment 10 is provided with a second bending segment 21, and the second bending segment 21 bends toward the third connecting segment 30 and extends toward the second connecting segment 20. When the frame 100 is matched with the laminated part, the second bending section 21 can be stopped against the surface of the laminated part, the protection of the surface of the laminated part can be increased, the fracture of the laminated part caused by the hard contact between the end part of the second connecting section 20 and the laminated part is avoided, and the structural strength of the second connecting section 20 can be increased by the arrangement of the second bending section 21, so that the better clamping of the laminated part is realized.
