Description

Technical Field

[0001] The invention relates to the technical field of profiles, and in particular to an aluminum profile for a photovoltaic bracket. Background Art

[0002] The profiles for photovoltaic brackets are used to form photovoltaic frames, thereby supporting the periphery of photovoltaic panels, playing a role in supporting, fixing and protecting photovoltaic panels.

[0003] Existing photovoltaic bracket profiles usually adopt a single-slot structure, with a cavity and a mounting surface arranged under the single slot. The cavity structure can improve the rigidity and strength of the profile, and is used for connection or extension to form a mounting surface. However, for the frame itself, not all mounting surfaces are used for actual installation, which leads to redundancy of unused mounting surfaces and cavity structures connected to the corresponding mounting surfaces, which is not conducive to reducing material usage and weight.

[0004] At present, some improvement plans are to reduce the cavity structure and set a connection notch structure at the bottom of the cavity. A separate connector is installed in the notch structure to achieve the installation and fixation of the frame, which greatly reduces the material usage and weight. However, the connection method at the bottom also has shortcomings. When the front of the photovoltaic panel is under pressure, such as in windy weather or rainy and snowy weather, the pressure from the photovoltaic panel will cause the inside of the frame to have downward pressure, while the outside of the frame has an upward traction force. This force forms a torsional moment through the force arm of the cavity along the vertical direction. This moment will act on the inner side of the lower side of the single groove and the connection between the connector and the notch. These parts are usually not used to bear the force, so they are generally weak in design. This also leads to the poor ability of these positions to withstand the pressure caused by wind pressure and rain and snow weight, and they are prone to stress fatigue or deformation.

[0005] How to improve the bearing capacity of photovoltaic bracket profiles against wind pressure and the weight of rain and snow while maintaining lightweight has become one of the technical problems that need to be solved urgently. Summary of the invention

[0006] In view of this, the present invention proposes an aluminum profile for a photovoltaic support, aiming to reduce the material and weight of the profile while improving the ability to resist wind, rain and snow.

[0008] In some embodiments, a glue overflow groove is provided on the lower surface of the upper wall.

[0009] In some embodiments, the width of the lower wall is greater than the distance between the limiting wall and the supporting wall.

[0010] In some embodiments, reinforcing ribs are provided on the supporting wall between the clamping wall and the lower wall.

DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0029] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the embodiments of the present invention belong. If the definitions set forth in this section are contrary to or otherwise inconsistent with the definitions set forth in the patents, patent applications, published patent applications, and other publications incorporated herein by reference, the definitions listed in this section take precedence over the definitions incorporated herein by reference.

[0032] like Figure 1 As shown, combined Figure 2-6 The aluminum profile for the photovoltaic bracket of the present invention includes: a supporting wall 1, an upper wall 2, a lower wall 3 and a clamping wall 4. The supporting wall 4 is vertically arranged, the upper wall 2 and the lower wall 3 are respectively vertically arranged on the upper edge and the lower edge of the same side of the supporting wall 4, the upper wall 2 and the lower wall 3 are parallel to each other, the clamping wall 4 is parallelly arranged between the upper wall 2 and the lower wall 3, and a photovoltaic installation groove is formed between the clamping wall 4 and the upper wall 2. A section of the clamping wall 4 away from the supporting wall 1 is bent downward to form a bending portion 41, and the end of the bending portion 41 extends toward the supporting wall 1 to form a limiting wall 42.

[0033] A groove for embedding the installation connection structure is formed between the limiting wall 42 and the lower wall 3. Compared with the conventional aluminum profile with a mounting surface, it saves more aluminum material and reduces the weight. At the same time, the installation groove formed between the limiting wall 42 and the lower wall 3 can provide better resistance to wind pressure and rain and snow pressure when the connecting structure is installed. When the photovoltaic panel is subjected to positive pressure, the middle of the photovoltaic panel tends to be concave. At this time, the stress mainly acts on the side of the clamping wall 4 away from the supporting wall 1. Due to the existence of the bending portion 41 and the filling effect of the connecting structure, a good supporting effect can be formed on the side of the clamping wall 4 away from the supporting wall 1 to resist wind pressure and rain and snow pressure.

[0034] In some embodiments, a glue overflow groove 21 is provided on the lower surface of the upper wall 2 .

[0035] The glue overflow groove 21 can effectively collect the glue overflowed when bonding the frame and the photovoltaic panel, thereby preventing the glue from dripping or flowing out of the frame and polluting the surrounding environment.

[0036] In some embodiments, the width of the lower wall 3 is greater than the distance between the limiting wall 42 and the supporting wall 1 .

[0037] In the above embodiments, the width of the lower wall 3 is greater than the distance between the limiting wall 42 and the supporting wall 1, which can provide a wider support area in the structure of the entire photovoltaic bracket, ensuring that the lower wall 3 can evenly share a larger load. By increasing the width of the lower wall, the bracket can more effectively withstand the pressure of the gravity from the photovoltaic panel and external environmental factors (such as wind pressure, etc.) on the bracket to avoid structural instability. The lower wall with a larger width can increase the contact area of ​​the support point, enhance the overall stability and pressure resistance of the photovoltaic bracket, thereby reducing the risk of deformation and damage. When the width of the lower wall is greater than the distance between the limiting wall 42 and the supporting wall 1, the fixing effect of the limiting wall 42 on the photovoltaic panel is more significant. The wider lower wall provides a stronger bottom support for the photovoltaic panel, so that the photovoltaic panel will not slip or tilt due to pressure. Under the action of external forces such as wind pressure and vibration, the design of a larger lower wall width can effectively increase the contact area between the photovoltaic panel and the bracket, enhance the connection strength and stability between them, and ensure that the photovoltaic panel can be firmly fixed under various conditions.

[0038] In some embodiments, a reinforcing rib 11 is provided on the supporting wall 1 between the clamping wall 4 and the lower wall 3 .

[0039] In the above embodiment, the reinforcing ribs 11 are arranged along the length direction of the profile where the supporting wall 1 is located, and the supporting wall 1 bears the vertical and horizontal pressure from the photovoltaic panel and the external environment. After the reinforcing ribs are arranged along the length direction, the bending resistance of the supporting wall 1 can be effectively increased when subjected to force. The bending of the supporting wall 1 is often caused by a large load acting on its central area. The arrangement of the reinforcing ribs 11 along the length direction can disperse and enhance the rigidity of the entire supporting wall 1 to prevent bending deformation.

[0040] In some embodiments, a connecting member 5 is also included, and the connecting member 5 includes a positioning portion 51 and a connecting portion 52. The positioning portion 51 is embedded between the clamping wall 4 and the limiting wall 42, and the connecting portion 52 is embedded between the limiting wall 42 and the lower wall 3. The connecting portion 52 protrudes from a side surface of the bending portion 41 away from the supporting wall 1 to form a connecting platform 50. The positioning portion 51 and the connecting portion 52 are fixedly connected.

[0041] In the above embodiments, the positioning portion 51 is embedded between the clamping wall 4 and the limiting wall 42, and the connector 5 can be accurately positioned in the correct position, so as to ensure the accurate assembly of the various components in the photovoltaic bracket and avoid installation problems caused by component displacement or misalignment. Through this precise embedding design, the connector can be firmly fixed to the structure of the bracket, avoiding the risk of looseness or instability. The connecting portion 52 protrudes from the side surface of the bending portion 41 away from the supporting wall 1, and forms a connecting platform 50, which provides a smooth and stable platform for the connection of other photovoltaic components or bracket components. The fixed connection between the positioning portion 51 and the connecting portion 52 ensures the overall stability of the connector. The connector can effectively disperse the externally applied load, reduce local stress concentration, and avoid deformation or damage to the photovoltaic bracket. The design of the connector 5 makes the installation and disassembly of each bracket component more convenient. Through the embedded structure, the connector not only ensures stability, but also simplifies the assembly process of the photovoltaic bracket.

[0042] In some embodiments, the positioning portion 51 includes a first wall 511, a second wall 512 and a third wall 513. The first wall 511 is parallel to the surface of the support wall 1, and the third wall 513 is parallel to the first wall 511. The upper and lower ends of the third wall 513 are respectively against the limiting wall 42 and the clamping wall 4.

[0043] In the above embodiments, the first wall 511 is parallel to the surface of the support wall 1, ensuring the close contact between the positioning portion 51 and the support wall 1, and ensuring that the connector will not be displaced or misplaced during the installation process. The design of the third wall 513 enables the positioning portion 51 to be fixed and closely abutted between the limiting wall 42 and the clamping wall 4, which can effectively ensure that the position of the connector in the photovoltaic bracket does not change, and the walls of the positioning portion 51 work together to form a firm fixed structure. The third wall 513 tightly connects the positioning portion 51 with the support wall 1 and other bracket structures, effectively preventing the risk of loosening of the connector due to external loads or vibrations. Since the positioning portion 51 provides stable support through multiple walls, it can effectively prevent the bracket from deforming under external environments (such as strong winds or vibrations). The structure formed between the first wall 511, the second wall 512 and the third wall 513 can work together when subjected to force to ensure the firmness and deformation resistance of the positioning part. In particular, the third wall 513 can provide additional support for the bending part 41 between the limiting wall 42 and the clamping wall 4, thereby improving the ability to resist wind pressure.

[0044] In some embodiments, the cross-section of the connecting portion 52 is a closed cavity, and the connecting portion 52 includes a fourth wall 521 , and the fourth wall 521 is coplanar with the first wall 511 .

[0045] The closed cavity structure can make the external force evenly distributed in the connection part 52, avoiding damage or deformation caused by local stress concentration. This can effectively reduce the potential risks caused by stress concentration when the photovoltaic bracket is subjected to large-scale pressure or vibration. The strength, rigidity, fatigue resistance and deformation resistance of the connector are further enhanced by setting the fourth wall 521 and the first wall 511 coplanar. The closed cavity not only provides a more uniform force distribution and efficient material use, but also improves the stability and reliability of the photovoltaic bracket system. This design makes the connector more firm and durable when subjected to long-term external forces, while reducing the weight of the system and optimizing the production and assembly process. At the same time, the connection platform 50 is also a cavity structure, thereby providing a more reliable installation performance for the external connection structure. For example, when bolts are used to connect the connector to the external structure, nuts can also be embedded in the cavity of the connection platform 50, thereby avoiding problems such as slipping or penetration damage to the connection platform 50.

[0046] In some embodiments, the connecting portion 52 further includes a fifth wall 522 , the fifth wall 522 is perpendicular to the fourth wall 521 , and the fifth wall 522 is coplanar with the limiting wall 42 .

[0047] In the above embodiments, the coplanar design ensures that the connection part 52 can be more firmly fixed in the overall structure of the photovoltaic support. This structural design helps the connection part 52 resist the action of external forces, especially by reducing the relative movement between the connection part 52 and the supporting component, reducing the risk of loosening or offset of the component. By making the fifth wall 522 coplanar with the limiting wall 42, a stronger support point is provided, further enhancing the rigidity and anti-deformation ability of the connection part. After adding the fifth wall 522, the structure of the connection part 52 is further reinforced, so that the impact resistance and fatigue resistance of the connection part are significantly improved. Especially in the case of dynamic loads, vibrations, etc., this structural design can effectively disperse the impact force and prevent excessive external forces from being concentrated in a small area. The design of the fifth wall 522 helps to increase the matching accuracy of the connection part with other supporting components. By design, it is ensured that the connection part 52 can be docked with the limiting wall 42 plane, reducing the problem of component misalignment or looseness caused by assembly errors. Through the design of the fifth wall 522, the connection part 52 can form a more closed structure to prevent external environmental factors (such as moisture, dust, corrosive substances) from damaging the inside of the bracket. The closed structure of the connection can effectively reduce the occurrence of corrosion, especially in harsh environments such as heavy humidity or at the seaside.

[0048] In some embodiments, the connecting portion 52 further includes a sixth wall 523 , which is integrally connected and disposed inside the sealed cavity, and the sixth wall 523 is coplanar with the third wall 513 .

[0049] In the above embodiments, the design of the sixth wall 523 further enhances the structural rigidity of the connection part 52. When the photovoltaic bracket is used for a long time, the external load may cause deformation of the connection part, and the sixth wall 523 effectively improves the deformation resistance of the connection part 52 and reduces loosening or deviation under the action of external force. Since the sixth wall is coplanar with the third wall, the inside and outside of the connection part 52 form a more stable mechanical support, thereby effectively improving the stability of the entire bracket. By arranging the sixth wall 523 on the inner side of the connection part 52, the bending resistance of the connection part is enhanced. This design can resist bending force and external impact force, especially when the load is heavy or subjected to a large external force, it can effectively prevent the connection part 52 from bending and deformation.

[0050] In some embodiments, a limiting boss 6 is further included. The limiting boss 6 is protrudingly disposed on the upper surface of the connecting platform 50 , and the limiting boss 6 and the surface of the bending portion 41 are mutually supported.

[0051] In the above embodiments, the design of the limiting boss 6 provides an additional mechanical locking point, further enhancing the fit between the connecting platform 50 and the bent portion 41 to prevent any relative displacement. The abutment between the boss and the bent portion ensures that the connector does not loosen or shift during use, thereby improving the overall stability of the photovoltaic bracket. In practical applications, this abutment effectively reduces the displacement or instability of the connection part caused by external forces (such as wind, vibration, etc.) after the bracket is installed. The limiting boss 6, as an additional contact point, disperses the external load to more parts and reduces the excessive pressure on a single connection point. This design optimizes the force distribution and avoids the damage or failure of the connector or structural components caused by excessive local force. By arranging the limiting boss 6 on the connecting platform 50, the connection between the connecting part and the bent portion 41 is more secure. This enables the photovoltaic bracket to withstand repeated loads and impacts more effectively during long-term use, especially under the action of external forces such as wind pressure and vibration, reducing fatigue damage caused by repeated use.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
