Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, specifically to a hollow thin-walled aluminum profile. Background Technology

[0002] In modern industrial manufacturing, particularly in sectors such as rail transportation, automotive lightweighting, aerospace, and high-end equipment manufacturing, aluminum profiles have become indispensable key structural materials due to their excellent strength-to-weight ratio, good corrosion resistance, and ease of processing. They are frequently used to construct main frames, supporting structures, and transmission systems, directly impacting the performance, energy consumption, and safety of the entire product. Traditional aluminum profile cross-section designs are often relatively simple, mostly single rectangular or circular hollow structures; their resistance to torsional deformation is weak, and when used as long members to bear complex loads, they are prone to instability, making it difficult to meet the application requirements of high strength and high stiffness.

[0003] Based on the above, this utility model proposes a hollow thin-walled aluminum profile, which can effectively solve the above problems. Utility Model Content

[0013] A hollow thin-walled aluminum profile includes an aluminum profile body with an axisymmetric cross-section. The aluminum profile body includes an outer frame 1 with a main chamber 2 at its center. The outer walls of the main chamber 2 are respectively provided with circular first connecting holes 3. The four corners of the outer frame 1 are respectively provided with square second connecting holes 4. The outer walls of the first connecting holes 3 and the outer walls of the second connecting holes 4 are fixedly connected by connecting arms 5.

[0014] This utility model ensures the uniformity and stability of the structural stress through axisymmetric design; the central main chamber 2 effectively reduces the overall weight of the profile, achieving lightweighting; the circular first connecting holes 3 on both sides and the square second connecting holes 4 at the four corners are connected to the outer frame 1 through connecting arms 5, which not only enhances the torsional and bending stiffness of the profile, but also improves the versatility and convenience of assembly with other components.

[0015] Furthermore, in another embodiment, each side wall of the outer frame 1 is provided with at least one T-shaped groove 6 extending along the length direction for assembling connectors.

[0016] By incorporating T-slots 6, the modular assembly capability and expandability of the aluminum profile are enhanced, enabling rapid installation and repositioning of various accessories without the need for additional drilling into the profile. This simplifies the assembly process.

[0017] Furthermore, in another embodiment, the inner wall of the first connecting hole 3 is provided with a plurality of first limiting ribs 7 evenly distributed at equal angles, and the first limiting ribs 7 extend along the length direction of the aluminum profile body.

[0018] By adding multiple equal-angled and evenly distributed first limiting ribs 7 inside the first connecting hole 3, the fitting accuracy and connection stability between the first connecting hole 3 and the connector are improved. The multi-point limiting effectively prevents the connector from rotating or shaking inside the hole, ensuring the reliability and accuracy of force transmission. At the same time, the hole wall is not easily deformed when subjected to pressure, further improving the overall rigidity and durability of the profile.

[0019] Furthermore, in another embodiment, a second limiting rib 8 is provided at the center of each inner wall of the second connecting hole 4, and the second limiting rib 8 extends along the length direction of the aluminum profile body.

[0020] By setting the second limiting rib 8 at the center of each inner wall of the second connecting hole 4, the positioning ability of the second connecting hole 4 and the connecting parts is enhanced, ensuring the firmness of the connection. At the same time, the hole wall is not easily deformed when subjected to pressure, further improving the overall rigidity and durability of the profile.

[0021] Furthermore, in another embodiment, the aluminum profile body is integrally extruded from aluminum alloy material.
