Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to reinforced frame profiles and frames. Background Technology

[0002] Photovoltaic frames are an essential component of solar photovoltaic modules and hold an irreplaceable position in the photovoltaic industry. The main function of the photovoltaic frame is to encapsulate the photovoltaic panel, providing stable support and ensuring its normal operation in various environments.

[0003] Currently, most photovoltaic (PV) frames are manufactured using a one-piece extrusion molding process, with the long and short sides then joined together. However, with the changing dimensions of PV modules, existing PV frame designs cannot meet the load testing requirements of ultra-large PV panels, such as those measuring 2465*1303. Figure 1 The frame structure shown (application number: 2025200968459) is prone to the following problems: the upper side b of the main frame is horizontally designed. After the photovoltaic panel a is installed, the upper side b of the main frame is prone to tilting downward under pressure, which may lead to collapse and leakage of sealant; the frame end c has insufficient structural strength and is prone to loosening; the double-layer folded edge of the free end d of the frame is too sharp, which may cause cracks in the material coating; the transition angle at the folded edge e of the frame reinforcing rib is too large, which may lead to lateral slippage failure under load pressure.

[0004] In view of this, it is necessary to improve the border structure in the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to disclose a reinforced frame profile and frame. The upper side of the main frame is arranged to be inclined upwards. On the one hand, it forms a dovetail angle with the end of the first side wall, which has a good anti-overflow effect. On the other hand, the upper side of the main frame is not easy to tilt, collapse or become unbalanced after being compressed. Moreover, the contact area with the photovoltaic panel is large after being compressed, resulting in good balance and improved load-bearing capacity. The reinforcing beam includes mutually perpendicular horizontal and vertical sections, which has a stronger load-bearing capacity and can avoid the transition angle of the reinforcing beam being too large. This prevents the inner side of the main frame from sliding under load, thus protecting the square stability of the main frame and improving load-bearing capacity. The free end of the second side wall forms a teardrop-shaped protrusion with pinholes inside, which reduces the difficulty of manufacturing and protects the material coating at the fold, preventing microcracks in the material coating. The double-layer double-inner-button closure is tight and the structure is stable.

[0006] To achieve the above objectives, this utility model provides a reinforced frame profile, which is cold-bent from a single sheet of steel and includes a main frame. The main frame has a cavity, the upper side of the main frame is inclined upward, and the upper end of the main frame has an upwardly extending first sidewall. An installation groove is formed between the first sidewall and the upper side of the main frame.

[0007] In some embodiments, the upper side of the main frame is tilted upward at an angle of 2.5°.

[0008] In some embodiments, the lower side of the main frame is provided with a first bending support extending into the cavity, and the inner side of the main frame is provided with a reinforcing beam, the first bending support abutting against the reinforcing beam.

[0009] In some embodiments, the reinforcing beam includes a horizontal section and a vertical section, and a second sidewall extends inward from the lower end of the main frame. The inner side of the main frame, the horizontal section, the vertical section, and the second sidewall are connected vertically in sequence, and the connection is arc-shaped.

[0010] In some embodiments, the free end of the second sidewall forms a teardrop-shaped protrusion.

[0011] In some embodiments, the free end of the first sidewall is a closed end, the free end of the inner layer plate of the first sidewall is closed inward, and the free end of the outer layer plate of the first sidewall covers the free end of the inner layer plate and is closed inward.

[0012] In some embodiments, a guide protrusion is provided at the upper end of the inner side of the main frame, and the guide protrusion is arranged close to the upper side of the main frame.

[0013] In some embodiments, the outer side of the main frame is provided with a second bending support extending into the cavity, and the second bending support abuts against the upper side of the main frame.

[0014] To achieve the above objectives, this utility model also provides a frame, which is spliced ​​together from the aforementioned reinforced frame profile.

[0015] In some implementations, the border includes a long side and a short side, which are connected by a corner code.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The upper side of the main frame is arranged to be inclined upward. On the one hand, it forms a dovetail angle with the end of the first side wall, which has a good anti-overflow effect. On the other hand, the upper side of the main frame is not easy to tilt, collapse or become unbalanced after being compressed. Moreover, the contact area with the photovoltaic panel is large after being compressed, which has good balance and improves the load-bearing capacity.

[0018] Second, the reinforced beams include mutually perpendicular horizontal and vertical sections, which have a stronger load-bearing capacity and can avoid excessive transition angles at the edges of the reinforced beams. This prevents the inner side of the main frame from slipping under load, protects the square stability of the main frame, and improves the load-bearing capacity.

[0019] Third, a teardrop-shaped protrusion is formed at the free end of the second sidewall, and pinholes are formed inside the teardrop-shaped protrusion, which reduces the difficulty of the process and realizes the protection of the material coating at the folded edge, preventing the material coating from cracking.

[0023] Figure 3 This is a structural diagram of the frame shown in this utility model. Detailed Implementation

[0024] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0025] As shown in Figure 2, the reinforced frame profile is formed from a single sheet of steel using a cold bending forming machine. This integrated molding process is simple, results in high structural stability, eliminates the need for fasteners, and reduces costs. The reinforced frame profile includes a main frame 1, within which a cavity 10 is provided for mounting corner brackets (not shown).

[0026] The main frame 1 has a first sidewall 2 extending upwards from its upper end. The first sidewall 2 extends vertically upwards first and then horizontally inwards. The free end of the first sidewall 2 is a closed end. The free end 5 of the inner layer plate of the first sidewall 2 is closed inwards, and the free end 6 of the outer layer plate of the first sidewall 2 covers the free end 5 of the inner layer plate and is closed inwards. This double-layer, double-closed-inward-closed design ensures a tight and stable structure. The photovoltaic panel 9 and the free end 6 of the outer layer plate of the first sidewall 2 are in surface contact, resulting in low pressure on the photovoltaic panel 9 and good anti-overflow adhesive effect. The steel plate located on the inside is called the inner layer plate, and the steel plate located on the outside is called the outer layer plate.

[0027] The upper side 11 of the main frame is inclined upward. On the one hand, it forms a dovetail angle with the end of the first side wall 2, which has a good anti-overflow effect. On the other hand, the upper side 11 of the main frame is not easy to tilt, collapse or become unbalanced after being pressed. Moreover, after being pressed, it has a large contact area with the photovoltaic panel 9, good balance, and improved load-bearing capacity.

[0028] The upper side 11 of the main frame is tilted upwards at an angle of 2.5°, meaning the angle between the upper side 11 and the horizontal line is 2.5°. At this angle, the load-bearing capacity of the upper side 11, the contact area between the upper side 11 and the photovoltaic panel 9, and the anti-overflow adhesive effect are optimal. If the angle is smaller than this, the load-bearing capacity and anti-overflow adhesive effect of the upper side 11 will be affected; if the angle is larger than this, it will affect the contact area between the upper side 11 and the photovoltaic panel 9 under pressure. An error of ±0.2° is allowed in actual production.

[0029] A mounting groove 3 is formed between the first sidewall 2 and the upper side edge 11 of the main frame. When installing the photovoltaic panel 9, the edge of the photovoltaic panel 9 needs to be extended into the mounting groove 3, and then sealant such as silicone is added between the photovoltaic panel 9 and the free end 6 of the outer layer of the first sidewall 2 to ensure that the photovoltaic panel 9 is firmly bonded to the frame 8. An overflow area 4 is formed between the first sidewall 2 and the mounting groove 3. Excess sealant enters the overflow area 4, which can prevent sealant leakage and ensure the aesthetics of the photovoltaic panel 9.

[0030] The lower end of the main frame 1 extends horizontally inward and is provided with a second sidewall 7, which facilitates connection with the photovoltaic bracket. The free end of the second sidewall 7 forms a teardrop-shaped protrusion 71, and pinholes are formed in the teardrop-shaped protrusion 71, which reduces the difficulty of the manufacturing process and protects the material coating at the folded edge, preventing microcracks in the material coating.

[0031] The lower side 12 of the main frame is provided with a first bending support 121 extending vertically upward into the cavity 10. The inner side 14 of the main frame is provided with a reinforcing beam 143. The first bending support 121 abuts against the reinforcing beam 143. The double-layer superposition improves the front load bearing capacity. On the one hand, it realizes the support of the lower side 12 to the inner side 14, improves the overall strength of the main frame 1, and improves the load-bearing capacity, torsional performance and bending performance of the main frame 1, preventing the main frame 1 from deforming after the photovoltaic panel 9 is installed. On the other hand, the first bending support 121 abuts against the reinforcing beam 143. This structure is integrally formed by cold bending of steel plate. The seamless connection eliminates the need for fasteners, simplifies the process, reduces costs, and saves time and effort. Furthermore, the reinforcing beam 143 includes mutually perpendicular horizontal sections 141 and vertical sections 142. The first bent support 121 abuts against the horizontal section 141, and the vertical section 142 fits against the first bent support 121. The first bent support 121 and the reinforcing beam 143 are in surface contact, resulting in a large contact area, high friction, better support effect, and stronger load-bearing capacity. It also avoids excessively large transition angles at the folded edges of the reinforcing beam 143, preventing the inner side 14 of the main frame from slipping under load, thus protecting the square stability of the main frame 1 and improving its load-bearing capacity.

[0032] The reinforcing beam 143 includes a horizontal section 141 and a vertical section 142. The inner side 14 of the main frame, the horizontal section 141, the vertical section 142, and the second sidewall 7 are connected vertically in sequence, and the connection is arc-shaped. An error of ±0.2° is allowed in actual production.

[0033] The upper end of the inner side 14 of the main frame is provided with a guide protrusion 144. The guide protrusion 144 is arranged close to the upper side 11 of the main frame. On the one hand, it increases the overall strength of the main frame 1 and prevents the main frame 1 from deforming after the photovoltaic panel 9 is installed. On the other hand, it facilitates the assembly of the frame 8 and the photovoltaic panel 9 and plays a guiding role in the installation of the photovoltaic panel 9.

[0034] The outer side 13 of the main frame is provided with a second bending support 131 extending into the cavity 10. The second bending support 131 extends horizontally inward and abuts against the upper side 11 of the main frame 1, thereby realizing the support of the outer side 13 to the upper side 11, improving the load-bearing capacity, torsional resistance and bending resistance of the main frame 1, and preventing the main frame 1 from deforming after the photovoltaic panel 9 is installed.

[0035] During installation, the photovoltaic panel 9 is placed on the upper side 11, which exerts direct pressure on the upper side 11 and the inner side 14. The lower side 12 supports the inner side 14, and the outer side 13 supports the upper side 11, which greatly improves the overall strength of the main frame 1 and effectively prevents the main frame 1 from deforming.

[0036] like Figure 3 The frame 8 shown is composed of two long sides 81 and two short sides 82, both of which are made of the reinforced frame profile described in this embodiment. The long sides 81 and short sides 82 are fixedly connected by corner brackets, with both ends of the corner brackets extending and fixed within the cavities 10 of the long sides 81 and 82, respectively. The connection method between the long sides 81, short sides 82, and corner brackets is existing technology and will not be described further here. Figure 2 Medium-strength frame profile is Figure 3 The AA section view of border 8 shown.
