Detailed implementation manners

[0033] The present utility model will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model. Embodiment 1

[0034] As Figure 1 and Figure 7 shown, a double-glass photovoltaic module frame includes a plurality of rigid frames 2 evenly distributed on the side of the photovoltaic module 1. In this embodiment, the number of rigid frames 2 is four;

[0035] The rigid frame 2 includes an outer frame 201 and a support frame 202. The support frame 202 is semi-covered on the glass on one side of the photovoltaic module 1, and elastic sheaths 3 are sleeved on both the support frame 202 and the glass on the other side of the photovoltaic module 1. In this example, the elastic sheath 3 is a rubber sleeve, where:

[0036] The outer frame 201 includes a first frame 2011 and a second frame 2012. One end of the first frame 2011 is covered on the sheath 3, and the other end is connected to the second frame 2012. The first frame 2011 deforms under the pressing external force and squeezes the sheath 3 to press the support frame 202 and the photovoltaic module 1. Specifically:

[0037] The support frame 202 is in an "L" shape. The top end of the support frame 202 is located in the sheath 3, and the top of the support frame 202 is flush with the glass layer at the top of the photovoltaic module 1. The bottom of the support frame 202 is covered on the glass layer at the bottom of the photovoltaic module 1. The top of the sheath 3 is covered on the top end of the support frame 202 and the glass layer at the top of the photovoltaic module 1. The bottom of the sheath 3 is covered on the bottom of the support frame 202. The top end of the first frame 2011 is covered on the top of the sheath 3. The bottom end of the first frame 2011 is connected to the top end of the second frame 2012. The bottom end of the second frame 2012 is covered on the bottom of the sheath 3 and bends and extends out of the sheath 3;

[0038] In order to achieve the electrical connection function of the module without adding extra accessories, the bottom end of the support frame 202 extends out of the sheath 3 and is bent by external force to fit with the second frame 2012. The electrical connection function is realized through the connection of the photovoltaic module 1, the support frame 202 and the second frame 2012. A spacing 4 is formed between the bent bottom end of the support frame 202 and the bottom end of the sheath 3 to prevent uneven stress on the sheath 3 after being squeezed. And the projected area of the bottom end of the support frame 202 on the horizontal plane is larger than the projected area of the top end of the support frame on the horizontal plane, which is used to increase the contact surface with the second frame 2012. While increasing the structural strength, the electrical connection effect is improved;

[0039] In order to improve the connection strength between the photovoltaic module 1 and the support frame 202, an adhesive layer 5 is also filled on the opposite side of the support frame 202 and the glass of the photovoltaic module 1. In this embodiment, the adhesive layer 5 is an adhesive film, and the support frame 202 and the photovoltaic module 1 are glued together.

[0040] A connection mechanism 6 for grounding is also provided on the outer frame 201. Specifically:

[0041] As Figure 5 shown, in this embodiment, the connection mechanism 6 includes a first connection plate 601; a first connection hole 7 is provided on the first connection plate 601. The first connection plate 601 is fixedly connected to one end of the second frame 2012 extending out of the sheath 3; the first connection plates 601 on the opposite sides of adjacent photovoltaic modules 1 are stacked so that the first connection holes 7 on the two first connection plates 601 coincide and are aligned. Bolts are used to fix and ground adjacent two photovoltaic modules 1 through the first connection holes 7 on the grounding side of the photovoltaic module 1. While realizing the grounding function, the fixing strength of adjacent photovoltaic modules 1 is improved, and the displacement of the photovoltaic module 1 is avoided. Embodiment Two

[0042] As Figure 2 and Figure 8 shown, a double-glass photovoltaic module frame includes a plurality of rigid frames 2 evenly distributed on the side of the photovoltaic module 1. In this embodiment, the number of the rigid frames 2 is four;

[0043] The rigid housing 2 includes an outer housing 201 and a support housing 202. The support housing 202 is semi - wrapped around the glass on one side of the photovoltaic module 1. Elastic sheaths 3 are sleeved on both the support housing 202 and the glass on the other side of the photovoltaic module 1. In this example, the elastic sheath 3 is a rubber sleeve, where:

[0044] The outer housing 201 includes a first housing 2011 and a second housing 2012. One end of the first housing 2011 is wrapped around the sheath 3, and the other end is connected to the second housing 2012. When the first housing 2011 is subjected to a pressing external force, it deforms and squeezes the sheath 3, pressing and supporting the housing 202 and the photovoltaic module 1. Specifically:

[0045] The support housing 202 is in an "L" shape. The top end of the support housing 202 is located in the sheath 3, and the top of the support housing 202 is flush with the glass layer at the top of the photovoltaic module 1. The bottom of the support housing 202 is wrapped around the glass layer at the bottom of the photovoltaic module 1. The top of the sheath 3 is wrapped around the top end of the support housing 202 and the glass layer at the top of the photovoltaic module 1. The bottom of the sheath 3 is wrapped around the bottom of the support housing 202. The top end of the first housing 2011 is wrapped around the top of the sheath 3. The bottom end of the first housing 2011 is connected to the top end of the second housing 2012. The bottom end of the second housing 2012 is wrapped around the bottom of the sheath 3 and bends and extends out of the sheath 3;

[0046] In order to achieve the electrical through - connection function of the module without adding extra accessories, the bottom end of the support housing 202 extends out of the sheath 3 and is bent by an external force to fit with the second housing 2012. The electrical through - connection function is realized through the connection of the photovoltaic module 1, the support housing 202, and the second housing 2012. A gap 4 is formed between the bottom end of the support housing 202 after bending and the bottom end of the sheath 3, which is used to prevent uneven stress on the sheath 3 when it is squeezed. And the projected area of the bottom end of the support housing 202 on the horizontal plane is larger than the projected area of the top end of the support housing on the horizontal plane, which is used to increase the contact surface with the second housing 2012. While increasing the structural strength, the electrical through - connection effect is improved;

[0047] In order to improve the connection strength between the photovoltaic module 1 and the support housing 202, an adhesive layer 5 is also filled on the opposite side of the support housing 202 and the glass of the photovoltaic module 1. In this example, the adhesive layer 5 is a film, which glues the support housing 202 and the photovoltaic module 1 together.

[0048] As Figure 3 、 Figure 4 and Figure 6 shown, a connection mechanism 6 for grounding is also provided on the outer housing 201. Specifically:

[0049] In this embodiment, the grounding mechanism includes a second connecting plate 602 and a third connecting plate 603. The second connecting plate 602 is fixedly connected to one end of the second frame 2012 extending out of the sheath 3. A groove 8 is formed between the second connecting plate 602 and the second frame 2012. A second connecting hole 9 is opened at the bottom of the groove 8. The second connecting hole 9 is connected to the grounding side through a bolt, which avoids the grounding interference between adjacent photovoltaic modules 1 and also saves the space in the horizontal direction, facilitating the laying of the photovoltaic modules 1.

[0050] The left and right sides of the third connecting plate 603 are respectively clamped to the first frames 2011 on the opposite sides of adjacent photovoltaic modules 1. The middle of the third connecting plate 603 has a depression. A third connecting hole 10 is opened at the depression of the third connecting plate 603. The third connecting hole 10 is connected to the grounding side of the photovoltaic module 1 through a bolt, which avoids the grounding interference between adjacent photovoltaic modules 1. While realizing the grounding function of the photovoltaic module 1, the third connecting plate 603 improves the fixing strength of adjacent photovoltaic modules 1.

[0051] Working principle

[0052] Fill the adhesive layer 5 on the opposite sides of the support frame 202 and the photovoltaic module 1 to glue the support frame 202 and the photovoltaic module 1. Then, clamp the elastic sheath 3 at the appropriate positions on the support frame 202 and the photovoltaic module 1. Finally, clamp the outer frame 201 on the sheath 3. Use a pressing device to press the first frame 2011 at the top of the outer frame 201 to deform the first frame 2011, and then use the pressing device to press the bottom end of the support frame 202 to make it bend and fit with the second frame 2012.
