Description

Technical Field

[0001] This utility model relates to the field of roll-formed profile technology, specifically to a photovoltaic module frame profile structure. Background Technology

[0002] Existing photovoltaic module frame structures are generally made of aluminum profiles. However, aluminum profiles have low strength, around 250 MPa. To ensure the strength and rigidity of the profile structure, the number and thickness of the profiles must be increased, such as... Figure 1 As shown, this results in high structural complexity and high quality. However, the price of aluminum is generally around 20,000 yuan, leading to high material costs. Furthermore, due to the need to connect with the bracket, the numerous and thick profile structures require CNC machining equipment to process mounting holes, positioning holes, drainage holes, notches, and other features, resulting in low overall processing efficiency and high costs.

[0003] To solve the above problems, there is currently a frame profile structure, such as... Figure 2 As shown, the material strength is S450. Although it improves the structural strength to a certain extent and reduces the number and thickness of the profile structure, there is still a problem that the overall structural strength cannot meet the usage requirements. Under stress, the structure will crack. In addition, the C-shaped groove structure for installing photovoltaic panels is also unreasonable, with low precision, which easily produces glue overflow. At the same time, there is stress release after assembly. After the frame groove position applies force to the photovoltaic panel, the excessive stress will damage the photovoltaic panel.

[0052] Example 1

[0053] like Figure 2 and Figure 3 As shown, this embodiment provides a photovoltaic module frame profile structure, including: a bottom wall 1, a first side wall 2, a second side wall 3, a supporting bottom wall 4, a first supporting top wall 5, a third side wall 6, and a second supporting top wall 7.

[0054] One end of the first sidewall 2 is connected to one end of the bottom wall 1; one end of the second sidewall 3 is connected to the other end of the bottom wall 1; one end of the receiving bottom wall 4 is connected to the other end of the second sidewall 3; one end of the first receiving top wall 5 is connected to the other end of the first sidewall 2; one end of the third sidewall 6 is connected to the other end of the receiving bottom wall 4; one end of the second receiving top wall 7 is connected to the other end of the first receiving top wall 5, and its other end is connected to the other end of the third sidewall 6. The receiving bottom wall 4, the third sidewall 6, the second receiving top wall 7, and the first receiving top wall 5 form a slot structure 8 for installing photovoltaic solar panels 11; the second receiving top wall 7, the first sidewall 2, and the first receiving top wall 5 form a first cavity structure 9; the second receiving top wall 7 and the first receiving top wall 5 form a second cavity structure 10. The second cavity structure 10 is a teardrop-shaped cavity. The slot structure 8 is approximately a C-shaped groove.

[0055] In this embodiment, at the position where the upper end of the slot of the slot structure 8 contacts the photovoltaic solar panel 11, two contact surfaces are formed by setting the first cavity structure 9 and the second cavity structure 10, which increases the contact area, reduces the contact pressure per unit area, and prevents the photovoltaic panel from being damaged due to the excessive strength of the steel profile structure.

[0056] The bottom wall 1, the first side wall 2, the second side wall 3, and the supporting bottom wall 4 form a third cavity structure 16, which is used to cooperate with the mounting bracket 17 for installation. The third cavity structure 16 is approximately rectangular in shape. The first supporting top wall 5, the first side wall 2, the bottom wall 1, the second side wall 3, the supporting bottom wall 4, the third side wall 6, and the second supporting top wall 7 are connected in sequence to form an integral structure; one end of the first supporting top wall 5 and one end of the second supporting top wall 7 are pressed together.

[0057] The other end of the first sidewall 2 is perpendicular to one end of the first supporting top wall 5. One end of the bottom wall 1 is perpendicular to one end of the first sidewall 2. The other end of the bottom wall 1 is bent to form a double-layer flange structure and is connected to one end of the second sidewall 3 through the inclined wall bending structure 15. The second sidewall 3 is parallel to the first sidewall 2. The other end of the second sidewall 3 is connected to one end of the supporting bottom wall 4 through the second U-shaped bending structure 14. The supporting bottom wall 4 is parallel to the bottom wall 1. The other end of the supporting bottom wall 4 is perpendicular to one end of the third sidewall 6. The third sidewall 6 is parallel to the first sidewall 2 and partially fits against it. The other end of the second supporting top wall 7 is connected to the other end of the third sidewall 6 through the step structure 71. The second supporting top wall 7 is parallel to the first supporting top wall 5 and partially fits against it. The other end of the first supporting top wall 5 is bent into the slot structure 8 to form an arc-shaped structure and is pressed against one end of the second supporting top wall 7 to form a teardrop-shaped cavity.

[0058] The first cavity structure 9 and the second cavity structure 10 are located at both ends of the first receiving top wall 5 and within the slot structure 8. When the photovoltaic solar panel 11 is installed into the slot structure 8, the photovoltaic solar panel 11 can abut against the first cavity structure 9 and the second cavity structure 10. A first overflow space 12 is formed between the second receiving top wall 7 and the side wall of the photovoltaic solar panel 11 through the first cavity structure 9 and the second cavity structure 10. A V-shaped channel 41 is provided on the receiving bottom wall 4. When the photovoltaic solar panel 11 is installed into the slot structure 8, a second overflow space 13 is formed between the receiving bottom wall 4 and the side wall of the photovoltaic solar panel 11 through the V-shaped channel 41.

[0059] In this embodiment, a cavity is formed inside the slot of the slot structure 8 by setting a first cavity structure 9, increasing structural strength. A teardrop-shaped cavity is added at the slot of the slot structure 8 by setting a second cavity structure 10, increasing the cavity strength and rigidity. At the same time, the ends of the material are pressed together to ensure the integrity of the structure. After the teardrop cavity on the outside of the slot and the cavity on the inside are attached to the photovoltaic panel, an overflow groove, i.e., the first overflow space 12, is formed inside. A groove, i.e., a V-shaped channel 41, is set at the bottom of the slot of the slot structure 8 for overflowing adhesive, while also increasing the rigidity and strength of the supporting surface.

[0060] The wall surface of the third side wall 6 is in contact with a portion of the wall surface of the first side wall 2, and a portion of the wall surface of the second supporting top wall 7 is in contact with a portion of the wall surface of the first supporting top wall 5; a stepped structure 71 is provided on the second supporting top wall 7, and the first cavity structure 9 is formed through the stepped structure 71. The second cavity structure 10 is formed by bending one end of the first supporting top wall 5 into the slot structure 8 and connecting it to the second supporting top wall 7.

[0061] A first U-shaped bend structure 21 is formed on the first sidewall 2; the first U-shaped bend structure 21 is connected to the receiving bottom wall 4 and is located below the receiving bottom wall 4 to support the receiving bottom wall 4. A second U-shaped bend structure 14 is formed at the connection position between the receiving bottom wall 4 and the second sidewall 3. A sloping wall bend structure 15 is formed at the connection position between the second sidewall 3 and the bottom wall 1.

[0062] In this embodiment, by setting the first U-shaped bending structure 21, a flange feature is added to the outer side to improve the structural support strength. By setting the second U-shaped bending structure 14, a flange feature is added to the inner side to improve the structural support strength. By setting the inclined wall bending structure 15, bending features are added to improve the structural rigidity, while saving some materials.

[0063] This embodiment provides a photovoltaic module frame roll-formed profile structure, mainly used to support the assembly of new energy photovoltaic panels. Using high-strength steel strip as raw material, the upper part of the structure is a C-shaped groove for photovoltaic panel assembly. The upper part of the groove has a two-cavity structure. At the outer bend of the upper left corner of the structure, a cavity is formed inside the groove to increase structural strength. A teardrop-shaped cavity is set inside the structure to increase the cavity's strength and rigidity. Simultaneously, the ends of the steel strip material are pressed together at this location to ensure the structural integrity.

[0064] Furthermore, in the structure of this embodiment, the inner sides of the two cavities form two contact surfaces with the photovoltaic panel. Having two such surfaces increases the contact area, reduces the contact pressure per unit area, and prevents damage to the photovoltaic panel due to excessive stress caused by the high strength of the steel profile structure. Simultaneously, an overflow groove for adhesive is formed at the upper end of the slot between the two cavities and the photovoltaic panel.

[0065] Furthermore, in the structure of this embodiment, the bottom support surface of the slot has an inwardly protruding channel in the length direction, which can also form an overflow groove and increase the rigidity of the support surface.

[0066] Furthermore, in the structure of this embodiment, the lower part of the C-shaped assembly slot of the photovoltaic panel is supported by two points, and a double-layer flange structure is provided. The added flange feature is used to improve the structural support strength. A bending structure is provided at the bottom of the overall structure, which can improve the structural strength and rigidity while saving materials. This structure is manufactured from the same steel strip, and the forming process is roll forming.

[0067] In this embodiment, the profile is made of high-strength automotive steel with a zinc-aluminum-magnesium coating, which has excellent corrosion resistance, ensuring a good appearance and resistance to corrosion and rust during service. At the same time, its strength reaches over 500 MPa, guaranteeing the overall structural bending and torsional strength, achieving both corrosion resistance and lightweight design.

[0068] The structure in this embodiment is made from the same steel strip and adopts an advanced roll forming process for online pre-punching and roll forming, resulting in good product quality, high production stability and efficiency.

[0069] For the structure of this embodiment, after the steel strip is passed through the roll forming mold, the two sides of the steel strip are rolled and bent multiple times to form a support cavity and a C-shaped groove. After the two ends of the steel strip at the outer edge of the groove are pressed together, an integral structure is formed.

[0070] This invention solves the technical problem of excess adhesive by setting a first cavity structure and a second cavity structure at the slot structure position, thereby improving the supporting strength of the frame profile structure.
