[0040] Embodiment 1

[0041] This embodiment provides a photovoltaic module frame, characterized in that it includes a frame body 101, the frame body 101 includes a substrate 1011 and a support plate 1012 arranged opposite to each other, and a first side plate 1013 and a second side plate 1014 connecting the substrate 1011 and the support plate 1012;

[0042] The first side plate 1013 extends a vertical side 102 in a direction away from the base plate 1011 , and a contact portion 103 is provided on the vertical side 102 , and the contact portion 103 extends in a direction toward the second side plate 1014 ;

[0043] A first boss 104 is provided at the extended end of the abutting portion 103, and the first boss 104 protrudes toward the supporting plate 1012;

[0044] A second boss 105 is disposed on the vertical edge 102 . The protruding direction of the second boss 105 is consistent with the extending direction of the abutting portion 103 , and the protruding height of the second boss 105 is smaller than the extending length of the abutting portion 103 .

[0045] In the field of photovoltaic cells, the outer edge of the laminate is wrapped with a frame, which provides mechanical support for the laminate and protects the cells, packaging materials, etc. inside the photovoltaic cell from external physical damage. The frame 101 enhances the overall rigidity of the component, enabling it to withstand external wind loads, snow loads and mechanical stress, thereby extending its service life.

[0046] Frames are usually used together with sealants and packaging materials to help encapsulate photovoltaic cells and prevent moisture, dust and other debris from entering the interior of photovoltaic modules, thereby keeping the internal environment of the module dry and clean and preventing electrical performance degradation or module damage caused by moisture or debris.

[0047] like Figure 1As shown, the panel at the bottom is a substrate 1011, which provides a solid bottom support for the photovoltaic module. The panel above the substrate 1011 is a support plate 1012, which is used to contact the laminate and provide support for the laminate. The left side is a first side plate 1013, and the right side is a second side plate 1014. Both ends of the first side plate 1013 and the second side plate 1014 are connected to the substrate 1011 and the support plate 1012 respectively. The substrate 1011, the first side plate 1013, the support plate 1012 and the second side plate 1014 are connected end to end to form a stable closed structure. Usually, the substrate 1011 and the support plate 1012 are of equal length and are arranged in parallel. The substrate 1011, the first side plate 1013, the support plate 1012 and the second side plate 1014 form a square structure.

[0048] The first side plate 1013 extends upwardly out of the vertical side 102, and the vertical side 102 is provided with an abutment portion 103, and the abutment portion 103 extends to the right side. The abutment portion 103, the vertical side 102 and the support plate 1012 surround a receiving groove, and the viscose can be poured into the receiving groove. The abutment portion 103 extends to the right side, that is, the extended end of the abutment portion 103 is the right end, and the first boss 104 is provided at the right end of the abutment portion 103, and the first boss 104 protrudes downward. Since the viscose has strong spreading and adhesion characteristics, the viscose on the lower wall of the abutment portion 103 will not fall directly onto the support plate 1012, but is attached to the lower wall of the abutment portion 103. The first boss 104 can block the viscose attached to the lower wall of the abutment portion 103 to prevent the viscose from overflowing from the edge of the abutment portion 103.

[0049] A second boss 105 is provided on the vertical edge 102, and the second boss 105 protrudes to the right, and the protruding height of the second boss 105 is smaller than the extended length of the abutting portion 103. The second boss 105 increases the bottom area of ​​a receiving groove formed by the abutting portion 103, the vertical edge 102 and the support plate 1012, that is, when the adhesive is poured into the receiving groove, the contact area between the receiving groove and the adhesive is increased, which can further improve the adhesion effect of the adhesive in the receiving groove.

[0050] Specifically, at least two second bosses 105 are arranged in parallel. It is understandable that when a boss is provided, there must be a depression relative to the boss, and the depression can be used as a glue storage tank. Together with the abutment portion 103 and the support plate 1012 provided on both sides of the second boss 105, at least two bosses are provided, that is, at least three glue storage tanks can be provided, and the glue is accommodated in the glue storage tank, increasing the contact area with the glue and improving the adhesion effect of the glue in the accommodation tank surrounded by the abutment portion 103, the vertical edge 102 and the support plate 1012.

[0051] In this embodiment, the abutment portion 103, the vertical edge 102 and the support plate 1012 form a receiving groove for receiving adhesive, a first boss 104 is provided on the abutment portion 103 to prevent the adhesive from overflowing from the edge of the abutment portion 103, and a second boss 105 is provided on the vertical edge 102 to increase the contact area with the adhesive, further improving the adhesive adhesion effect in the receiving groove. When used for framing and combining with laminated parts, it can effectively reduce the front glue overflow, ensure that the silicone glue overflow between the laminated parts and the frame is uniform and the contact area is increased, the sealing is good, and the mechanical load performance and long-term reliability of the component are improved.

[0052] In one embodiment, the extension length of the abutting portion 103 is 1 to 4 mm. According to laboratory verification, the anti-overflow effect is best when the extension length of the abutting portion 103 is within the range of 1 to 4 mm.

[0053] Embodiment 2

[0054] On the basis of the first embodiment, the second boss 105 includes a first raised portion 1051 and a second raised portion 1052 . The first raised portion 1051 is disposed between the abutting portion 103 and the second raised portion 1052 . Both the first raised portion 1051 and the second raised portion 1052 are sloped raised portions.

[0055] like Figure 5 and Figure 6 As shown, the second boss 105 includes a first protrusion 1051 and a second protrusion 1052. The first protrusion 1051 is arranged above the second protrusion 1052, and the protrusion direction is toward the second protrusion 1052 below, while the second protrusion 1052 is arranged below the first protrusion 1051, and the protrusion direction is toward the first protrusion 1051 above. Along the protrusion direction of the first protrusion 1051 and the second protrusion 1052, both can guide the adhesive, guide the flow direction of the adhesive, and avoid adhesive overflow. The first protrusion 1051 and the second protrusion 1052 are both slope-shaped protrusions, with a wide bottom and a narrow top at the protrusion position, and a stable structure. The slope-shaped protrusion surface can also guide the flow direction of the adhesive to a certain extent, thereby improving the bonding quality.

[0056] In one embodiment, Figure 8 As shown, the slope angle of the second protrusion 1052 close to the support plate 1012 is less than or equal to 30°, and the slope angle of the second protrusion 1052 away from the support plate 1012 is less than or equal to 40°;

[0057] The slope angle of the first protrusion 1051 on the side close to the abutting portion is less than or equal to 40°.

[0058] The slope angle is the angle between the raised plane and the slope surface after the raised surface. The first raised portion 1051 and the second raised portion 1052 are both raised from the side wall of the vertical side. The vertical side 102 extends in the vertical direction. The slope angles of the first raised portion 1051 and the second raised portion 1052 are both the angles from the vertical direction to the slope surface after the raised surface.

[0059] The flow of the adhesive depends on the surface tension of the adhesive and the adhesion to the contact member. The slope angle of the second raised portion 1052 close to the support plate 1012 is less than or equal to 30°, and the slope angle is relatively gentle, which is conducive to the adhesive gathered on the support surface flowing upward along the slope. The slope angle of the second raised portion 1052 away from the support plate 1012 is less than or equal to 40°, and the slope is also a gentle slope, which will not form a large depression, and prevent the adhesive from flowing to this position to form bubbles. The slope angle of the first raised portion 1051 close to the abutment portion is less than or equal to 40°, which guides the adhesive and makes the adhesive flow in the direction of the slope, which is conducive to uniform distribution of the adhesive and avoids adhesive overflow.

[0060] Specifically, the slope angle of the second raised portion 1052 close to the support plate 1012 can be set to 20°, and the slope angle of the side away from the support plate 1012 can be set to 35°; the slope angle of the first raised portion 1051 close to the abutting portion can be set to 35°.

[0061] In this embodiment, by limiting the slope angle of the slope-shaped protrusion, damage to the adhesive layer due to tension concentration during the gluing process is effectively avoided, while the adhesion of the colloid is enhanced, making the photovoltaic module frame more stable and reliable during use.

[0062] Embodiment 3

[0063] like Figures 1 to 4 As shown, based on the first embodiment, the second boss 105 is bent and tilted toward the abutting portion 103 .

[0064] In this embodiment, the second boss 105 is bent and tilted upward. The bending part of the second boss 105 and the side wall of the vertical edge 102 form a groove, which is conducive to accommodating the adhesive. The second boss 105 is bent and tilted upward. The upward tilted edge can play a guiding role, guiding the adhesive upward. The vertical edge 102, the abutment portion 103 and the first boss 104 jointly enclose a larger groove at the top, and the adhesive can be guided upward to the larger groove at the top. Ensure the uniformity of silicone filling and overflow, while ensuring the reliability of sealing.

[0065] Embodiment 4

[0066] On the basis of the first embodiment, a glue overflow groove 106 is provided on the bearing surface of the support plate 1012 .

[0067] In this embodiment, the bearing surface of the support plate 1012 can be in contact with the laminate and used to bear the laminate. The overflow glue groove 106 is set on the bearing surface. During bonding, excess glue can flow into the overflow glue groove 106 to avoid excessive glue overflow during the bonding process, which helps to optimize the use of glue and overflow glue control during the bonding process and improve the bonding effect. Usually, the overflow glue groove 106 is rectangular, U-shaped or V-shaped.

[0068] In one embodiment, the glue overflow groove 106 is disposed on the rear half of the bearing surface of the support plate 1012 away from the first side plate 1013. Figure 3 and Figure 4 As shown, the glue overflow groove 106 is arranged on the right side of the support surface of the support plate 1012, which can better control the flow direction of the glue during the bonding process and reduce the impact of the overflow glue on the component structure.

[0069] In one embodiment, a plurality of overflow glue grooves 106 are arranged in parallel. The capacity of a single overflow glue groove 106 is limited, and a plurality of overflow glue grooves 106 are arranged in parallel to accommodate more glue, ensuring that the glue is evenly applied to the entire bonding area.

[0070] Furthermore, the spacing between the plurality of overflow glue grooves 106 is equal. The plurality of overflow glue grooves 106 are arranged in parallel with equal spacing, so that more uniform glue coating can be achieved, thereby improving the bonding effect.

[0071] Embodiment 5

[0072] like Figure 3 and Figure 4 As shown, on the basis of the fourth embodiment, the support plate 1012 extends an extended edge 107 in a direction away from the first side plate 1013 , and a glue overflow groove 106 is provided on the extended edge 107 .

[0073] In this embodiment, the extended edge 107 is a further extension of the support plate 1012, which increases the contact area between the support surface of the support plate 1012 and the laminate, so as to improve the stability of the support of the laminate. The extended edge 107 is also provided with a glue overflow groove 106, which provides additional space for setting the glue overflow groove 106, increases the distribution area of ​​the glue overflow groove 106, and helps to better control the coating area of ​​the glue.

[0074] Embodiment 6

[0075] On the basis of the first embodiment, a front half bearing surface of the support plate 1012 close to the first side plate 1013 is provided with a slope toward the first side plate 1013 .

[0076] like Figure 7As shown, the support surface on the left side of the support plate 1012 is provided with an inclined surface inclined toward the lower left. The setting of the inclined surface reduces the physical volume of the support plate 1012. The vacant space can accommodate more glue, which is beneficial to avoid glue overflow and improve the bonding effect.

[0077] Embodiment 7

[0078] like Figure 7 As shown, this embodiment provides a photovoltaic component 200, including a photovoltaic laminate 201 and at least one photovoltaic component frame 100 as any one of Embodiments 1 to 7, the bottom surface of the photovoltaic laminate 201 is in contact with the support plate 1012, the side wall of the photovoltaic laminate 201 is in contact with the abutment 103, and the thickness of the photovoltaic laminate 201 is greater than or equal to the distance from the abutment 103 to the support plate 1012.

[0079] The beneficial effects of the photovoltaic assembly 200 of this embodiment are equivalent to the beneficial effects of the photovoltaic assembly frame 100 described above, and will not be described in detail here.

[0080] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
