[0039] Figure 1 Schematic diagram of a photovoltaic assembly frame according to some embodiments of the present application.

[0040] One or more embodiments of the present application disclose a photovoltaic module frame. Figures 1 to 4 The frame of the photovoltaic module is formed by bending a profile plate multiple times. The frame is bent from top to bottom in sequence to connect a frame clamping area 14 and a frame cavity area 41; the frame includes a top beam 10, a cross beam 30 and a bottom beam 50. The cross beam 30 is connected to the top beam 10 and the bottom beam 50 by bending multiple times. The frame clamping area 14 is formed between the top beam 10 and the cross beam 30. The frame cavity area 41 is formed between the cross beam 30 and the bottom beam 50. The cross beam 30 is bent inward from the side wall 20 of the top beam and then bent in the opposite direction to the side wall 40 of the bottom beam. The cross beam 30 is provided with a cavity 39 and at least one bending structure. The cavity 39 is formed in the cross beam 30, and the bending structure is at least partially bent from the connecting end of the cross beam 30 toward the cavity 39.

[0041] That is, the cross beam 30 first bends and extends from the side wall 20 of the top beam toward the photovoltaic module, and then bends and extends away from the photovoltaic module to be connected with the side wall 40 of the bottom beam. It can be understood that the cross beam 30 of the photovoltaic module frame is bent and indented multiple times, which is conducive to improving the torsion and bending resistance of the cross beam 30, thereby improving the structural strength and support strength of the cross beam 30, so that the photovoltaic module frame can more reliably support the photovoltaic module.

[0042] In addition, the cavity 39 of the beam 30 can increase the vertical height of the beam 30, which is conducive to further improving the structural strength of the beam 30. In addition, the bending structure can increase the deformation freedom of the beam 30, which is conducive to improving the toughness of the beam 30, and the cavity 39 can provide a deformation space, so that when the photovoltaic module frame is subjected to external force, the bending structure and the cavity 39 are conducive to causing the beam 30 to produce a small range of elastic deformation, thereby improving the toughness of the photovoltaic module frame, and helping to reduce the risk of the photovoltaic module frame being broken when subjected to external force.

[0043] In some embodiments, reference Figures 1 to 4The cross beam 30 includes a first mounting edge 33, a second mounting edge 34 and a connecting edge 300. The second mounting edge 34 is located below the first mounting edge 33. The first mounting edge 33 extends from the side wall 20 of the top beam toward the photovoltaic component. The connecting edge 300 is bent to connect the first mounting edge 33 and the second mounting edge 34. The second mounting edge 34 extends toward the side wall 40 of the bottom beam on the side facing away from the photovoltaic component. A cavity 39 is formed between the first mounting edge 33, the second mounting edge 34 and the connecting edge 300. The bending structure is arranged on the first mounting edge 33 and / or the second mounting edge 34.

[0044] Specifically, in at least one embodiment, the bending structure is located at the connection end of the first mounting edge 33, so as to be connected between the side wall 20 of the top beam and the first mounting edge 33, and the bending structure protrudes toward the second mounting edge 34, which is conducive to increasing the number of bendings at the connection between the first mounting edge 33 and the side wall 20 of the top beam, thereby facilitating the improvement of the toughness and structural strength of the cross beam 30. In at least one embodiment, the bending structure is located at the connection end of the second mounting edge 34, so as to be connected between the side wall 40 of the bottom beam and the second mounting edge 34, and the bending structure protrudes toward the first mounting edge 33, thereby facilitating the improvement of the toughness and structural strength of the cross beam 30. In at least one embodiment, the bending structure is connected between the second mounting edge 34 and the connecting edge 300, thereby facilitating the improvement of the number of bendings at the connection between the second mounting edge 34 and the connecting edge 300, thereby facilitating the improvement of the connection strength between the second mounting edge 34 and the connecting edge 300, thereby facilitating the improvement of the support strength of the cross beam 30. It can be understood that the bending structure can be arranged at any one or more of the three positions: the connecting end of the first mounting edge 33 and the side wall 20 of the top beam, the connecting end of the second mounting edge 34 and the side wall 40 of the bottom beam, and between the second mounting edge 34 and the connecting edge 300, and the present application does not impose any specific restrictions on this.

[0045] In some embodiments, reference Figures 1 to 4 The connecting edge 300 is an inclined edge, a vertical edge or an arc-shaped edge, so that the connecting edge 300 is inclined and bent to connect the first mounting edge 33 and the second mounting edge 34, or the connecting edge 300 is vertically bent to connect the first mounting edge 33 and the second mounting edge 34, or the connecting edge 300 is arc-shaped and bent to connect the first mounting edge 33 and the second mounting edge 34. It can be understood that the first mounting edge 33 and the second mounting edge 34 are connected and supported by the connecting edge 300, and then a cavity 39 is formed between the first mounting edge 33, the connecting edge 300 and the second mounting edge 34, so that the vertical height of the cross beam 30 is increased, which is conducive to further improving the structural strength of the cross beam 30.

[0046] Specifically, in at least one embodiment, refer to Figure 1The connecting edge 300 is bent obliquely to connect the first mounting edge 33 and the second mounting edge 34, and the connecting edge 300 and the first mounting edge 33 are connected at an obtuse angle. When installing the photovoltaic module, the connecting edge 300 can guide the photovoltaic module, which is conducive to sliding the side edge of the photovoltaic module into the frame clamping area 14 along the connecting edge 300. In addition, the obliquely arranged connecting edge 300 can increase the contact area, so that the force of the beam 30 is more dispersed. In at least one embodiment, referring to Figure 2 The connecting edge 300 is vertically bent to connect the first mounting edge 33 and the second mounting edge 34, which is beneficial to improving the toughness and structural strength of the beam 30, thereby improving the bearing capacity of the beam 30, so that the beam 30 can more reliably support the photovoltaic module.

[0047] In some embodiments, reference Figure 1 The bending structure includes a first bending structure 301, which is arranged at the connection end between the second mounting edge 34 and the side wall 40 of the bottom beam. The first bending structure 301 is bent from the second mounting edge 34 toward the cavity 39 and connected to the side wall 40 of the bottom beam, which is beneficial to increase the number of bending times at the connection between the second mounting edge 34 and the side wall 40 of the bottom beam, thereby improving the connection strength between the side wall 40 of the bottom beam and the second mounting edge 34, so that the side wall 40 of the bottom beam supports the second mounting edge 34 more reliably, thereby helping to improve the toughness and structural strength of the cross beam 30.

[0048] Further, the first bending structure 301 includes a first auxiliary edge 37 and a second auxiliary edge 38, the first auxiliary edge 37 is bent upward from the second mounting edge 34 to connect the first auxiliary edge 37, and the first auxiliary edge 37 is bent and connected to the side wall 40 of the bottom beam, specifically, the first auxiliary edge 37 is vertically bent from one end of the second mounting edge 34 away from the connecting edge 300, the second auxiliary edge 38 is horizontally bent from one end of the first auxiliary edge 37 away from the second mounting edge 34, and connected to the side wall 40 of the bottom beam, and the second auxiliary edge 38 is suitable for abutting against the first mounting edge 33, which is conducive to the second auxiliary edge 38 supporting the first mounting edge 33, further improving the bearing capacity of the cross beam 30. In addition, a cavity 39 is formed between the first mounting edge 33, the connecting edge 300, the second mounting edge 34 and the first auxiliary edge 37, so as to increase the vertical height of the cross beam 30, which is conducive to further improving the structural strength of the cross beam 30.

[0049] In some embodiments, reference Figure 2 and Figure 3The bending structure further includes a second bending structure 302, which is arranged at the connection end between the first mounting edge 33 and the side wall 20 of the top beam, and the second bending structure 302 is bent from the first mounting edge 33 to the direction of the cavity 39 and connected to the side wall 20 of the top beam, wherein the second bending structure 302 includes a third auxiliary edge 31 and a fourth auxiliary edge 32, and the fourth auxiliary edge 32 is bent downward from the first mounting edge 33 and connected to the third auxiliary edge 31, and the third auxiliary edge 31 is bent and connected to the side wall 20 of the top beam. It can be understood that the second bending structure 302 is helpful to increase the number of bending times at the connection between the first mounting edge 33 and the side wall 20 of the top beam, thereby helping to improve the toughness and structural strength of the cross beam 30.

[0050] It is worth mentioning that, through the second bending structure 302 , a glue overflow groove 15 is formed between the side wall 20 of the top beam, the third auxiliary edge 31 and the fourth auxiliary edge 32 , thereby increasing the capacity of the frame clamping area 14 , which is beneficial to further prevent glue from overflowing from the frame clamping area 14 .

[0051] In some embodiments, reference Figure 3 and Figure 4 The bending structure further includes a third bending structure 303, which is arranged at the connection end between the second mounting edge 34 and the connecting edge 300, and the third bending structure 303 is bent from the second mounting edge 34 to the direction of the cavity 39 and connected to the connecting edge 300, wherein the third bending structure 303 includes a fifth auxiliary edge 35 and a sixth auxiliary edge 36, the fifth auxiliary edge 35 is bent upward from the second mounting edge 34 and connected to the sixth auxiliary edge 36, and the sixth auxiliary edge 36 is bent and connected to the connecting edge 300. It can be understood that the third bending structure 303 is conducive to improving the connection strength between the second mounting edge 34 and the connecting edge 300, thereby improving the support strength of the beam 30.

[0052] Specifically, in at least one embodiment, refer to Figure 1The first mounting edge 33 extends laterally from one end of the side wall 20 of the top beam away from the top beam 10 toward the photovoltaic module, thereby forming a platform for supporting the photovoltaic module. The connecting edge 300 extends obliquely from one end of the first mounting edge 33 away from the side wall 20 of the top beam, so that the connecting edge 300 and the first mounting edge 33 are connected at an obtuse angle, so that the connecting edge 300 can guide the photovoltaic module. The second mounting edge 34 extends laterally from one end of the connecting edge 300 away from the first mounting edge 33 toward the side wall 40 of the bottom beam, and the second mounting edge 34 and the first mounting edge 33 are arranged approximately parallel. The first auxiliary edge 37 is bent vertically upward from one end of the second mounting edge 34 away from the connecting edge 300, and the second auxiliary edge 38 is bent horizontally from one end of the first auxiliary edge 37 away from the second mounting edge 34 to be connected to the side wall 40 of the bottom beam, and the second auxiliary edge 38 is suitable for abutting against the first mounting edge 33, which is conducive to the second auxiliary edge 38 supporting the first mounting edge 33, further improving the bearing capacity of the beam 30. It can be understood that the first auxiliary edge 37 and the second auxiliary edge 38 of the first bending structure 301 are conducive to increasing the number of bending times at the connection between the second mounting edge 34 and the side wall 40 of the bottom beam, thereby improving the connection strength between the side wall 40 of the bottom beam and the second mounting edge 34. After multiple bending and indentation, the beam 30 is conducive to improving the structural strength and support strength of the beam 30, so that the beam 30 can more reliably carry the photovoltaic module.

The first mounting edge 33 extends laterally from one end of the fourth auxiliary edge 32 away from the third auxiliary edge 31 toward the photovoltaic module to form a platform for supporting the photovoltaic module. It can be understood that the third auxiliary edge 31 and the fourth auxiliary edge 32 of the second bending structure 302 are helpful to increase the number of bending times at the connection between the first mounting edge 33 and the side wall 20 of the top beam, thereby improving the connection strength between the first mounting edge 33 and the side wall 20 of the top beam, which is helpful to improve the toughness and structural strength of the beam 30. The connecting edge 300 extends vertically from one end of the first mounting edge 33 away from the fourth auxiliary edge 32, which is beneficial to improve the toughness and structural strength of the cross beam 30, thereby improving the bearing capacity of the cross beam 30, so that the cross beam 30 can more reliably support the photovoltaic module. The second mounting edge 34 extends laterally from one end of the connecting edge 300 away from the first mounting edge 33 toward the side wall 40 of the bottom beam, and the second mounting edge 34 and the first mounting edge 33 are arranged approximately parallel. The first auxiliary edge 37 is vertically bent upward from one end of the second mounting edge 34 away from the connecting edge 300, and the second auxiliary edge 38 is laterally bent from one end of the first auxiliary edge 37 away from the second mounting edge 34 to be connected to the side wall 40 of the bottom beam, and the second auxiliary edge 38 is suitable for abutting against the third auxiliary edge 31, which is beneficial for the second auxiliary edge 38 to support the first bending structure 301 and the first mounting edge 33, further improving the bearing capacity of the cross beam 30. It is understandable that the beam 30 undergoes multiple bending and indentation, which is beneficial to improving the structural strength and support strength of the beam 30, so that the beam 30 can more reliably carry the photovoltaic components.

The first mounting edge 33 extends laterally from one end of the fourth auxiliary edge 32 away from the third auxiliary edge 31 toward the photovoltaic module to form a platform for supporting the photovoltaic module. It can be understood that the third auxiliary edge 31 and the fourth auxiliary edge 32 of the second bending structure 302 are helpful to increase the number of bending times at the connection between the first mounting edge 33 and the side wall 20 of the top beam, thereby improving the connection strength between the first mounting edge 33 and the side wall 20 of the top beam, which is helpful to improve the toughness and structural strength of the crossbeam 30. The connecting edge 300 is bent, and the sixth auxiliary edge 36 extends transversely from the end of the connecting edge 300 away from the first mounting edge 33 toward the side wall 40 of the bottom beam, and the sixth auxiliary edge 36 and the first mounting edge 33 are stacked and arranged approximately in parallel, so as to enhance the structural strength of the cross beam 30. The fifth auxiliary edge 35 is bent vertically downward from the end of the sixth auxiliary edge 36 away from the connecting edge 300, and the second mounting edge 34 is bent transversely from the end of the fifth auxiliary edge 35 away from the sixth auxiliary edge 36 to be connected to the side wall 40 of the bottom beam, and the second mounting edge 34 is suitable for abutting against the third auxiliary edge 31, and the second mounting edge 34 and the fifth auxiliary edge 35 are covered on the outer peripheral side of the second bending structure 302, which is conducive to the second mounting edge 34 and the fifth auxiliary edge 35 supporting the first bending structure 301 and the first mounting edge 33, and further improving the bearing capacity of the cross beam 30. It is understandable that the beam 30 undergoes multiple bending and indentation, which is beneficial to improving the structural strength and support strength of the beam 30, so that the beam 30 can more reliably carry the photovoltaic components.

[0055] In at least one embodiment, reference Figure 4The third auxiliary edge 31 is bent from one end of the side wall 20 of the top beam away from the top beam 10 and extends laterally toward the photovoltaic module, and the fourth auxiliary edge 32 is bent from one end of the third auxiliary edge 31 away from the side wall 20 of the top beam and extends vertically upward to form a second bending structure 302. The first mounting edge 33 extends laterally from one end of the fourth auxiliary edge 32 away from the third auxiliary edge 31 toward the photovoltaic module to form a platform for supporting the photovoltaic module. It can be understood that the third auxiliary edge 31 and the fourth auxiliary edge 32 of the second bending structure 302 are helpful to increase the number of bending times at the connection between the first mounting edge 33 and the side wall 20 of the top beam, thereby improving the connection strength between the first mounting edge 33 and the side wall 20 of the top beam, which is helpful to improve the toughness and structural strength of the crossbeam 30. The connecting edge 300 is bent, and the sixth auxiliary edge 36 extends laterally from the end of the connecting edge 300 away from the first mounting edge 33 toward the side wall 40 of the bottom beam, and the sixth auxiliary edge 36 and the first mounting edge 33 are approximately parallel and stacked, so as to enhance the structural strength of the cross beam 30. The fifth auxiliary edge 35 is bent vertically downward from the end of the sixth auxiliary edge 36 away from the connecting edge 300, the second mounting edge 34 is bent laterally from the end of the fifth auxiliary edge 35 away from the sixth auxiliary edge 36, the first auxiliary edge 37 is bent vertically upward from the end of the second mounting edge 34 away from the connecting edge 300, and the second auxiliary edge 38 is bent laterally from the end of the first auxiliary edge 37 away from the second mounting edge 34, so as to be connected to the side wall 40 of the bottom beam, and the second auxiliary edge 38 is suitable for abutting against the third auxiliary edge 31, which is conducive to the second auxiliary edge 38 supporting the first bent structure 301 and the first mounting edge 33, and further improving the bearing capacity of the cross beam 30. Furthermore, a cavity 39 is formed between the first mounting edge 33, the fifth auxiliary edge 35, the second mounting edge 34 and the first auxiliary edge 37. It is understandable that the beam 30 undergoes multiple bending and indentation, which is beneficial to improving the structural strength and support strength of the beam 30, so that the beam 30 can more reliably carry the photovoltaic module.

[0056] In some embodiments, reference Figures 5 to 13 The bottom beam 50 includes a bottom edge, and the bottom edge is bent and connected to the side wall 40 of the bottom beam. The bottom edge includes a first bottom edge 51, a boss structure and a second bottom edge 52. The boss structure protrudes from the bottom edge toward the frame cavity area 41. The first bottom edge 51 and the second bottom edge 52 are located on both sides of the boss structure. The boss structure includes a first raised edge 53 and a second raised edge 55. The first raised edge 53 is an inclined edge, a vertical edge or an arc-shaped edge, and the second raised edge 55 is an inclined edge, a vertical edge or an arc-shaped edge. It can be understood that the boss structure can increase the number of bending times of the bottom beam 50, thereby improving the torsion and bending resistance of the bottom beam 50, so that the bottom beam 50 can more stably support the frame of the photovoltaic module, and is beneficial to improving the overall structural strength of the frame of the photovoltaic module. It is worth mentioning that, with reference to Figures 1 to 4The bottom edge may also be flat, and this application does not impose any specific limitation on this.

[0057] Specifically, in at least one embodiment, the first raised edge 53 and the second raised edge 55 are both inclined edges, and the first raised edge 53 and the boss edge 54, and the second raised edge 55 and the boss edge 54 are connected at an obtuse angle, which is conducive to reducing the stress concentration at the connection of each edge. In at least one embodiment, the first raised edge 53 is a vertical edge, and the second raised edge 55 is an inclined edge, that is, the first raised edge 53 and the boss edge 54 are approximately vertically connected, and the second raised edge 55 and the boss edge 54 are connected at an obtuse angle, which is conducive to improving the torsion and bending resistance of the bottom beam 50 and enhancing the structural strength of the bottom beam 50. In at least one embodiment, the first raised edge 53 and the second raised edge 55 are both vertical edges, that is, the first raised edge 53 and the boss edge 54, and the second raised edge 55 and the boss edge 54 are approximately vertically connected, which is conducive to further improving the torsion and bending resistance of the bottom beam 50 and enhancing the structural strength of the bottom beam 50.

[0058] In some embodiments, reference Figures 5 to 7 ,as well as Figures 11 to 13 The bottom beam 50 includes a bottom edge and a free end 60. The free end 60 is rotated from the end of the bottom edge toward the side wall 40 of the bottom beam to be trimmed, which is beneficial to improving the structural strength and aesthetics of the end of the bottom beam 50, reducing the risk of tearing at the end of the bottom beam 50, and during the installation process, it is beneficial to prevent the end of the bottom beam 50 from scratching the construction workers.

[0059] Specifically, in at least one embodiment, refer to Figures 5 to 7 The free end 60 is bent from the end of the second bottom edge 52 toward the side wall 40 of the bottom beam, and the free end 60 is parallel to the bottom wall. Figures 11 to 13 The free end 60 is bent back from the end of the second bottom edge 52 toward the side wall 40 of the bottom beam, and the end of the free end 60 is against the second bottom edge 52 .

[0060] In some embodiments, reference Figures 1 to 4 The top beam 10 is provided with a first top edge 13, a third mounting edge 12 and a second top edge 11. The first top edge 13 is bent to connect the side wall 20 of the top beam and the third mounting edge 12. The second top edge 11 is gradually bent from the third mounting edge 12 to the frame clamping area 14, so as to reduce the opening of the frame clamping area 14, which is beneficial to improving the anti-overflow performance of the photovoltaic module frame.

[0061] It can be understood that the frame clamping area 14 is used to accommodate the side of the photovoltaic module and the glue, and the second top edge 11 is gradually bent from the third installation edge 12 to the frame clamping area 14, so as to reduce the opening of the frame clamping area 14, thereby facilitating the glue from overflowing from the frame clamping area 14. In addition, the second top edge 11 is bent toward the frame clamping area 14, which is conducive to improving the clamping force of the second top edge 11 on the side of the photovoltaic module, thereby improving the connection reliability between the photovoltaic module frame and the photovoltaic module.
