Description
Technical Field
[0001] The invention relates to the technical field of aluminum alloy profiles, in particular to an aluminum alloy profile reinforced with carbon fiber composite materials. Background Art
[0002] In modern industry and aerospace, advances in materials science play a vital role in improving product performance and reducing costs. Aluminum alloys are generally used in various engineering structures and product manufacturing due to their light weight, high strength, and corrosion resistance. Carbon fiber composites, with their excellent mechanical properties and lightweight characteristics, show great potential as reinforcing materials. Carbon fiber, due to its extremely high strength and modulus as well as good heat resistance and corrosion resistance, has become an ideal reinforcing material. By integrating carbon fiber composites into aluminum alloy profiles, the mechanical properties of aluminum alloys, such as tensile strength, rigidity, and fatigue resistance, can be significantly improved.
[0003] Announcement number CN209278823U is an aluminum alloy profile reinforced with carbon fiber composite materials. It has solved the technical disadvantage that the profile cannot be reinforced with carbon fiber composite materials and is only bonded to the outer surface of the profile by structural adhesive, which cannot overcome the technical disadvantage that the adhesive layer is easily peeled off and damaged when the profile is bent. However, in actual use, similar structures still have many defects. For example, the existing aluminum alloy profile adopts an one-piece molding structure, which cannot flexibly adjust the strength of the structure according to actual needs; and when it is locally damaged, it needs to be replaced as a whole, resulting in increased maintenance costs in the later stage.

[0031] The following will be combined with the Figure 1 To the attached Figure 9 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0032] An aluminum alloy profile reinforced with carbon fiber composite material includes an aluminum alloy profile outer liner 1, an aluminum alloy profile inner liner 3, and a locking mechanism 4. An assembly hole 103 is defined within the aluminum alloy profile outer liner 1. Four dovetail clips 2 are fixedly mounted on the inner wall of the assembly hole 103. The four dovetail clips 2 are arranged in a circular array around the inner wall of the assembly hole 103. Conical limiting holes 201 are equidistantly defined on the inner walls of the four dovetail clips 2.
[0033] It should be noted that the aluminum alloy profile outer lining 1 plays a supporting and protective role, providing basic shape constraints and protection for the overall structure, and provides an installation point through the assembly hole 103 thereon; the aluminum alloy profile inner lining 3 serves as a reinforcement structure and can be assembled according to mechanical strength requirements; the locking mechanism 4 is a key locking mechanism that can firmly fix the aluminum alloy profile inner lining 3 inside the assembly hole 103, thereby enhancing the strength and stability of the overall structure; the assembly hole 103 is composed of four equidistantly distributed dovetail clips 2 forming a special-shaped snap-fit structure, which allows the aluminum alloy profile inner lining 3 to be quickly snap-fitted to the aluminum alloy profile outer lining 1 through the special-shaped snap-fit structure;
[0034] The aluminum alloy profile liner 3 is mounted inside the assembly hole 103 by means of four dovetail clips 2. A locking groove 303 is defined in the center of the aluminum alloy profile liner 3. A plurality of dovetail grooves 3031 are defined inside the locking groove 303. The locking mechanism 4 is inserted into the locking groove 303 through the dovetail grooves 3031.
[0035] It should be noted that the assembly hole 103 is used to fix the aluminum alloy profile lining 3; a locking groove 303 is provided inside the aluminum alloy profile lining 3, and a dovetail groove 3031 is provided inside the locking groove 303, providing an installation position for the locking mechanism 4; the locking mechanism 4 is engaged with the dovetail groove 3031, thereby fixing the aluminum alloy profile lining 3 in the assembly hole 103; the design of the dovetail clamp 2 and the locking mechanism 4 ensures rapid disassembly and assembly between the aluminum alloy profile lining 3 and the aluminum alloy profile outer lining 1, and facilitates flexible adjustment of the aluminum alloy profile assembly structure according to the actual mechanical strength requirements;
[0036] The aluminum alloy profile inner lining 3 is locked in the assembly hole 103 by the locking mechanism 4, so that the aluminum alloy profile inner lining 3 and the aluminum alloy profile outer lining 1 can be quickly disassembled and assembled, and the aluminum alloy profile inner lining 3 and the aluminum alloy profile outer lining 1 can be assembled according to the mechanical strength requirements of use;
[0037] It should be noted that the mortise and tenon structure design adopted by the locking mechanism 4 realizes the tool-free rapid assembly and disassembly of the aluminum alloy profile lining 3 and the aluminum alloy profile outer lining 1. The aluminum alloy profile lining 3 is aligned with the assembly hole 103 on the aluminum alloy profile outer lining 1 and inserted, and a mortise and tenon connection is formed through the dovetail clamp 2 and the dovetail clamping groove 301. Then, the locking mechanism 4 is aligned with the locking groove 303 in the aluminum alloy profile lining 3 and inserted. The locking mechanism 4 is clamped through the dovetail groove 3031 in the locking groove 303 to achieve the fixation and locking of the aluminum alloy profile lining 3 and form a mortise and tenon connection. The three-dimensional directional locking is achieved through geometric constraints, effectively suppressing the relative sliding of the aluminum alloy profile outer lining 1 and the aluminum alloy profile lining 3.
[0038] The aluminum alloy profile inner lining 3 and the aluminum alloy profile outer lining 1 can be quickly and conveniently assembled and disassembled through the locking mechanism 4, and the strength of the structure can be flexibly adjusted according to actual needs without sacrificing the convenience of installation and disassembly. This not only improves assembly efficiency, but also enhances the adaptability and flexibility of the structure, making it suitable for a variety of different application scenarios. Moreover, when the local structure is damaged, the aluminum alloy profile inner lining 3 and the dovetail clamp 2 can be quickly released through the locking mechanism 4, making it convenient to pull out the aluminum alloy profile inner lining 3 for disassembly. This allows the damaged aluminum alloy profile outer lining 1 or aluminum alloy profile inner lining 3 to be replaced without having to replace the entire structure, thereby reducing maintenance costs.
[0039] To disassemble the locking mechanism 4, specifically, the round rod 401 in the locking mechanism 4 is pulled out to release the arc end surface of the locking rod 403 from interfering with the locking mechanism 4, so that the locking rod 403 drives the conical stopper 404 to move along the track of the mounting hole 307. Figure 8 、 Figure 9 It can be seen that a magnet is embedded in the interior of the conical limit head 404, and a limiting groove is provided at one end of the mounting through hole 307, and a magnet ring is embedded in the limiting groove. The magnet embedded in the conical limit head 404 and the magnet ring embedded in the limiting groove generate a magnetic attraction force to magnetically move the conical limit head 404 to the limiting groove at one end of the mounting through hole 307, so that the conical limit head 404 is away from the conical limit hole 201, and the aluminum alloy profile lining 3 and the dovetail clamp 2 are released, making it convenient to pull out the aluminum alloy profile lining 3 for disassembly.
[0040] like Figures 6 to 9As shown, the locking mechanism 4 consists of a round rod 401, four dovetail locks 402, a locking rod 403 and a tapered stopper 404. The four dovetail locks 402 are distributed in a circular array on the outside of the round rod 401. An equidistant locking rod 403 is movably installed between every two dovetail locks 402. One end of the locking rod 403 is provided with an arcuate end surface that fits the arc surface of the round rod 401. The tapered stopper 404 is fixedly installed on the other end of the locking rod 403 and extends into the interior of the tapered stopper hole 201.
[0041] It should be noted that the four dovetail locks 402 are arranged in a circular array on the outside of the round rod 401. They not only provide support but also enable the locking rod 403 to accurately move along the track of the mounting through hole 307 through positioning. When the round rod 401 is inserted into the locking groove 303, the arcuate end surface of the round rod 401 is in contact with the arcuate surface. The arcuate surface pushes the locking rod 403 to move along the track of the mounting through hole 307, so that the locking rod 403 drives the tapered stopper 404 to move into the tapered stopper hole 201.
[0042] The locking rod 403 is movably extended to the mounting through hole 307, and the arc-shaped end surface of one end of the locking rod 403 fits with the outer surface of the round rod 401, so that the conical limit head 404 at the other end of the locking rod 403 extends to the conical limit hole 201, thereby locking the aluminum alloy profile lining 3 in the dovetail slot 301, so that the aluminum alloy profile lining 3 and the aluminum alloy profile outer lining 1 are firmly assembled and connected.
[0043] like Figures 1 to 5 As shown, the outer side of the aluminum alloy profile outer lining 1 is provided with equidistant heat dissipation grooves, and the interior of the heat dissipation grooves is provided with equidistant heat dissipation fins 101. The four corners of the interior of the aluminum alloy profile outer lining 1 are provided with equidistant first lightweight holes 102. A reinforcement is provided in the center of the first lightweight hole 102, and reinforcement ribs are provided on both sides of the reinforcement.
[0044] It should be noted that the heat dissipation fins 101 arranged on the surface of the outer lining 1 of the aluminum alloy profile effectively improve the overall heat exchange efficiency of the profile by increasing the heat dissipation area, so that the aluminum alloy profile can still maintain structural stability in a high-temperature working environment; the structure of the outer lining 1 of the aluminum alloy profile is lightweight through the first lightweight hole 102, and the reinforcement and reinforcement ribs arranged inside the first lightweight hole 102 balance the strength, rigidity and stability of the structure, ensuring that the safety performance requirements can be met under various working conditions.
[0045] like Figures 4 and 5 As shown, first reinforcing ribs 104 are equidistantly installed on the inner wall of the assembly hole 103;
[0046] It should be noted that, by means of the equally distributed first reinforcing ribs 104 , the force can be evenly distributed to each first reinforcing rib 104 , thereby avoiding excessive stress in a certain area and ensuring the stability and durability of the aluminum alloy profile outer lining 1 .
[0047] like Figure 4 、 Figure 6 As shown, four dovetail slots 301 are equidistantly provided on the outer side of the aluminum alloy profile lining 3, and the dovetail slots 301 coincide with the dovetail clips 2;
[0048] It should be noted that the dovetail slots 301 evenly distributed on the outside of the aluminum alloy profile lining 3 correspond to the dovetail clips 2, and the aluminum alloy profile lining 3 is accurately installed by overlapping the dovetail clips 2 and the dovetail slots 301. The dovetail clips 2 are tightly combined with the dovetail slots 301 due to their unique dovetail shape, ensuring that the connection and support in different directions are more firm, effectively preventing problems such as loosening and falling off due to external forces.
[0049] like Figure 4 、 Figure 6 As shown, second lightweight holes 302 are equidistantly formed at the four corners of the inner lining 3 of the aluminum alloy profile, and each second lightweight hole 302 is located between two dovetail slots 301. Third lightweight holes 306 are equidistantly formed outside the locking slot 303, and the third lightweight holes 306 are located between the locking slot 303 and the dovetail slot 301.
[0050] It should be noted that the dovetail clip 2 and the dovetail slot 301 are used to form a mortise and tenon connection, and locking is achieved through the locking mechanism 4, which effectively suppresses the relative sliding of the aluminum alloy profile lining 3 and the aluminum alloy profile outer lining 1; the setting of the second lightweight hole 302 and the third lightweight hole 306 reduces the weight of the aluminum alloy profile lining 3 itself.
[0051] like Figure 4 、 Figure 6 As shown, the outer side of the aluminum alloy profile lining 3 is adhered with a carbon fiber composite layer 305 via an adhesive layer 304 , and the inner wall of the dovetail slot 301 is adhered with a carbon fiber composite layer 305 via an adhesive layer 304 ;
[0052] It should be noted that the adhesive layer 304 is used to ensure that the carbon fiber composite layer 305 can be firmly attached to the aluminum alloy profile lining 3, thereby improving the stability and durability of the overall structure; the carbon fiber composite layer 305 significantly improves the load-bearing capacity and fatigue resistance of the structure due to its high specific strength and high specific modulus characteristics; the inner wall of the dovetail slot 301 is adhered with the carbon fiber composite layer 305 in the same manner, further enhancing the strength and durability of the connection, making the overall structure more stable; the overall structure is achieved while maintaining lightweight while having excellent mechanical properties and durability.
[0053] like Figures 2 to 5 As shown, the four dovetail slots 301 are provided with mounting holes 307 at equal distances therefrom. The mounting holes 307 pass through the third lightweight hole 306 and extend to the dovetail slot 3031 .
[0054] It should be noted that before assembling the aluminum alloy profile lining 3 and the aluminum alloy profile outer lining 1, the locking rod 403 is first inserted into each mounting through hole 307 accordingly, so that the conical limit head 404 is retracted into the limit groove at one end of the mounting through hole 307, so that the end face of the conical limit head 404 is in the same plane as the outer side of the aluminum alloy profile lining 3, which does not affect the insertion of the aluminum alloy profile lining 3 into the plug-in cavity formed by the dovetail clip 2 and the assembly hole 103.
[0055] like Figure 6 、 Figure 8 、 Figure 9 As shown, the inner wall of the dovetail clamp 2 is provided with a second reinforcing rib 202, and the tapered limiting hole 201 is connected to the installation through hole 307;
[0056] It should be noted that the second reinforcing rib 202 increases the structural strength of the dovetail clip 2 to prevent deformation when subjected to external force; the conical limit hole 201 provides a plug-in position for the conical limit head 404, and the mounting through hole 307 docked with the conical limit hole 201 facilitates moving the conical limit head 404 in the limit groove at one end of the mounting through hole 307 along the mounting through hole 307 to the conical limit hole 201, thereby locking the aluminum alloy profile lining 3 in the dovetail slot 301 and ensuring that the aluminum alloy profile lining 3 will not slide in the dovetail slot 301.
[0057] Based on the explanations and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are only for convenience of description and do not constitute any limitation to the present invention.
