Description

Technical Field

[0001] This utility model relates to the field of aluminum profile technology, and more specifically, to a honeycomb core reinforced high-strength compressive aluminum profile. Background Technology

[0002] In fields such as construction, aerospace, and automobiles, there are high requirements for the strength and compressive strength of aluminum profiles. The important characteristics of aluminum profiles are their development towards high performance, high precision, energy saving, environmental protection, and high strength and compressive strength. However, when aluminum profiles are used, their poor compressive strength often limits their application. During long-term use, they may deform, which will affect the functionality of the product. Therefore, there are high requirements for the strength and compressive strength of aluminum profiles.

[0003] Existing aluminum profiles are generally hollow, with many having excessively large cavities and unreasonable zoning. This significantly reduces the compressive strength, load-bearing capacity, and rigidity of the aluminum profiles. During handling or use, external forces may cause deformation of the aluminum profiles, affecting their functionality and appearance.

[0004] A search revealed that Chinese patent CN220582207U discloses a high-strength, pressure-resistant aluminum profile. This structure has low manufacturing costs. By coordinating the outer pressure ring, pressure block, pressure plate, inner pressure ring, pressure-resistant components, and pressure-resistant plate within the aluminum profile body, the compressive strength of the aluminum profile can be significantly improved. This results in better compressive strength for the aluminum profile body, solving the problem that existing profiles, when subjected to high pressure, have weak compressive strength and are prone to deformation after prolonged use, affecting their normal use. This reduces the probability of profile deformation, thereby ensuring the normal use of the profile.

[0005] However, in actual use, the transition area between the outer bearing ring and the aluminum profile body, and the welding points between the pressure-resistant components and the bearing plate are prone to stress concentration. Under cyclic loads, fatigue cracks are easily triggered, eventually leading to structural fracture and affecting the performance. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a honeycomb core reinforced high-strength compressive aluminum profile to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A honeycomb core reinforced high-strength compressive aluminum profile includes an aluminum profile body, wherein multiple fixing rings are fixedly arranged on the inner wall of the aluminum profile body, multiple honeycomb-shaped support frames are fixedly arranged on one side of the fixing rings, and a compressive resistance mechanism is arranged on one side of the honeycomb-shaped support frames.

[0009] The anti-compression mechanism includes an inner pressure-bearing ring fixedly disposed on one side of a honeycomb-shaped support frame. A honeycomb core is fixedly disposed inside the inner pressure-bearing ring. Multiple reinforcing strips are fixedly disposed inside the honeycomb core. A triangular support frame is fixedly disposed on one side of each reinforcing strip. Multiple anti-compression plates are fixedly disposed on the inner wall of the honeycomb-shaped support frame. A reinforcing layer is fixedly disposed on the inner wall of the honeycomb-shaped support frame. The reinforcing layer is made of carbon fiber reinforced epoxy resin.

[0010] By adopting the above technical solution, a multi-level pressure dispersion path is formed by the fixed ring, honeycomb support frame and anti-compression mechanism. Moreover, the honeycomb core combined with the reinforcing strip and triangular support frame utilizes the biomimetic structure to efficiently disperse pressure. The carbon fiber reinforced epoxy resin reinforcement layer is combined with the anti-compression plate to improve rigidity from the material level. The multi-dimensional synergistic effect not only ensures the structural stability of the aluminum profile under pressure, but also meets the requirements of lightweighting.

[0011] As a further description of the above technical solution: an auxiliary mechanism is provided on one side of the fixed ring, the auxiliary mechanism including a plurality of fixed cylinders fixedly disposed on one side of the fixed ring, a fixed rod being slidably disposed inside the fixed cylinder, and one end of the fixed rod being connected to the surface of the honeycomb support frame;

[0012] Multiple springs are fixedly installed between the fixing ring and the honeycomb support frame, and the springs are sleeved on the surface of the fixing cylinder and the fixing rod.

[0013] By adopting the above technical solutions, pressure buffering and structural reset functions are achieved, effectively improving the deformation resistance and fatigue life of aluminum profiles under dynamic pressure, and ensuring long-term structural stability and reliability.

[0014] As a further description of the above technical solution: a heat insulation layer is fixedly provided on the surface of the aluminum profile body, the heat insulation layer is made of polyurethane foam, and a wear-resistant coating is fixedly provided on the surface of the heat insulation layer, the wear-resistant coating is made of ceramic coating material;

[0015] A waterproof layer is fixedly provided on the surface of the wear-resistant coating. The waterproof layer is made of silicone coating material. The surface of the honeycomb support frame has multiple weight-reducing holes, which are equilateral triangles.

[0016] By adopting the above technical solutions, the polyurethane foam insulation layer can effectively block heat and prevent the aluminum profile from being affected by temperature changes in its internal structure. The equilateral triangular weight-reducing holes on the honeycomb support frame utilize the stability of the triangular structure to reduce the weight of the aluminum profile while ensuring that its compressive strength is not affected, thus achieving a balance between lightweight and high performance.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. By setting up a compression-resistant mechanism, compared with the existing technology, the external pressure is initially dispersed by the fixed ring and then transmitted to the inner pressure-bearing ring through the honeycomb support frame. The honeycomb structure of the internal honeycomb core can evenly distribute the pressure to each honeycomb cell, avoiding stress concentration at a single point. Combined with the stabilizing structure of the reinforcing strip and the triangular support frame, a multi-level compression-resistant path is formed, which significantly improves the reliability of the structure under pressure. Moreover, the compression plate of the inner wall of the honeycomb support frame is made of carbon fiber reinforced epoxy resin, which provides basic compression strength, while the reinforcing layer further improves the overall rigidity with its high strength and high modulus characteristics. The synergistic effect of the two can effectively resist pressure deformation, so that the structure can still maintain shape stability when subjected to heavy loads.

[0019] 2. By setting up auxiliary mechanisms, compared with existing technologies, the sliding structure composed of the fixed cylinder and the fixed rod, together with the sleeved spring, generates a reverse elastic force through the elastic deformation of the spring when the honeycomb support frame is compressed and displaced. This effectively absorbs the pressure impact energy, reduces the amplitude of structural vibration, and improves the stability and fatigue resistance of the aluminum profile under periodic or instantaneous pressure. In addition, the polyurethane foam insulation layer blocks heat conduction, avoids the material's thermal expansion and contraction deformation caused by drastic temperature changes, and protects the internal structure. The ceramic wear-resistant coating resists external friction loss with its high hardness characteristics, reducing surface wear damage. The organic silicone waterproof layer forms a hydrophobic barrier to prevent rust caused by moisture penetration. The three layers of protection are progressively enhanced, comprehensively improving the durability of the aluminum profile in complex environments such as high temperature, high humidity, and strong friction.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The embodiments disclosed in this application are as follows: Figure 1-5 The honeycomb core reinforced high-strength compressive aluminum profile shown includes an aluminum profile body 1, a plurality of fixing rings 2 are fixedly arranged on the inner wall of the aluminum profile body 1, a plurality of honeycomb support frames 3 are fixedly arranged on one side of the fixing rings 2, and a compressive mechanism is arranged on one side of the honeycomb support frames 3.

[0028] The compression-resistant mechanism includes an inner pressure-bearing ring 4 fixedly installed on one side of the honeycomb support frame 3, a honeycomb core 5 fixedly installed inside the inner pressure-bearing ring 4, multiple reinforcing strips 6 fixedly installed inside the honeycomb core 5, a triangular support frame 7 fixedly installed on one side of the reinforcing strip 6, multiple compression-resistant plates 8 fixedly installed on the inner wall of the honeycomb support frame 3, and a reinforcing layer 9 fixedly installed on the inner wall of the honeycomb support frame 3. The reinforcing layer 9 is made of carbon fiber reinforced epoxy resin.

[0029] When the aluminum profile body 1 is subjected to external pressure, the pressure is first transmitted to the inner wall of the aluminum profile body 1. Multiple fixing rings 2 fixed on the inner wall play a role in initially dispersing the pressure and transmitting the pressure to the honeycomb support frame 3 on one side of the fixing ring 2.

[0030] The anti-compression mechanism on one side of the honeycomb support frame 3 begins to play a major anti-compression role. The inner pressure ring 4 directly bears the pressure transmitted from the honeycomb support frame 3, and the honeycomb core 5 inside it disperses the pressure to each honeycomb cell through its unique honeycomb structure.

[0031] Multiple reinforcing strips 6 inside the honeycomb core 5 further enhance the compressive strength of the honeycomb core 5 and transfer the pressure to the triangular support frame 7. Due to its stable structural characteristics, the triangular support frame 7 can effectively resist pressure deformation and evenly distribute the pressure to the honeycomb support frame 3.

[0032] Furthermore, the compression plate 8 and reinforcing layer 9 on the inner wall of the honeycomb support frame 3 work together through carbon fiber reinforced epoxy resin material. The compression plate 8 provides basic compressive strength, while the reinforcing layer 9, with its high strength and high modulus, further enhances the compressive performance of the honeycomb support frame 3, jointly resisting external pressure.

[0033] Reference Figure 2-3 As shown, an auxiliary mechanism is provided on one side of the fixed ring 2. The auxiliary mechanism includes multiple fixed cylinders 10 fixedly disposed on one side of the fixed ring 2. A fixed rod 11 is slidably disposed inside the fixed cylinder 10. One end of the fixed rod 11 is connected to the surface of the honeycomb support frame 3.

[0034] Multiple springs 12 are fixedly installed between the fixed ring 2 and the honeycomb support frame 3. The springs 12 are sleeved on the surface of the fixed cylinder 10 and the fixed rod 11.

[0035] The fixed cylinder 10 on one side of the fixed ring 2 and the fixed rod 11 slidably disposed inside form a sliding connection structure. When the honeycomb support frame 3 is subjected to pressure and produces a small displacement, the fixed rod 11 slides inside the fixed cylinder 10.

[0036] Furthermore, the multiple springs 12 sleeved on the surfaces of the fixing cylinder 10 and the fixing rod 11 between the fixing ring 2 and the honeycomb support frame 3 undergo elastic deformation when the honeycomb support frame 3 is displaced, generating a reverse elastic force to help the honeycomb support frame 3 return to its original position, playing a buffering and stabilizing role, and further enhancing the compressive strength of the aluminum profile.

[0037] Reference Figure 4-5 As shown, a heat insulation layer 13 is fixedly provided on the surface of the aluminum profile body 1. The heat insulation layer 13 is made of polyurethane foam. A wear-resistant coating 14 is fixedly provided on the surface of the heat insulation layer 13. The wear-resistant coating 14 is made of ceramic coating material.

[0038] A waterproof layer 15 is fixedly provided on the surface of the wear-resistant coating 14. The waterproof layer 15 is made of silicone coating material. Multiple weight-reducing holes 16 are opened on the surface of the honeycomb support frame 3. The weight-reducing holes 16 are in the shape of an equilateral triangle.

[0039] The surface of the aluminum profile body 1 is covered with a heat insulation layer 13 made of polyurethane foam. When the external temperature changes, its good heat insulation performance prevents heat from being transferred to the interior of the aluminum profile body 1, thus playing a role in heat insulation and protecting the internal structure of the aluminum profile from the influence of temperature changes.

[0040] Secondly, the surface of the heat insulation layer 13 is made of a wear-resistant coating 14 made of ceramic coating material. When the aluminum profile is subjected to friction, its high hardness and wear resistance protect the aluminum profile body 1 from wear and extend the service life of the aluminum profile.

[0041] In addition, the surface of the wear-resistant coating 14 is made of a waterproof layer 15 made of silicone coating material, which forms a waterproof barrier when it comes into contact with water or a humid environment, preventing moisture from penetrating into the interior of the aluminum profile body 1, preventing the aluminum profile from rusting and corroding, and further enhancing the durability of the aluminum profile.

[0042] Multiple equilateral triangular weight-reduction holes 16 are opened on the surface of the honeycomb support frame 3. Without affecting the overall structural strength, the weight of the aluminum profile is reduced by reducing the amount of material used, thus reducing the overall load. At the same time, the equilateral triangular shape design can ensure the stability of the structure and maintain the compressive strength of the aluminum profile while reducing weight.

[0043] Working principle of this utility model:

[0044] This utility model is a honeycomb core reinforced high-strength compressive aluminum profile. When the aluminum profile body 1 is subjected to external pressure during use, the pressure is first transmitted to the inner wall of the aluminum profile body 1. Multiple fixing rings 2 fixed on the inner wall play a role in initially dispersing the pressure and transmitting the pressure to the honeycomb support frame 3 on one side of the fixing ring 2.

[0045] The anti-compression mechanism on one side of the honeycomb support frame 3 begins to play a major anti-compression role. The inner pressure ring 4 directly bears the pressure transmitted from the honeycomb support frame 3, and the honeycomb core 5 inside it disperses the pressure to each honeycomb cell through its unique honeycomb structure.

[0046] Multiple reinforcing strips 6 inside the honeycomb core 5 further enhance the compressive strength of the honeycomb core 5 and transfer the pressure to the triangular support frame 7. Due to its stable structural characteristics, the triangular support frame 7 can effectively resist pressure deformation and evenly distribute the pressure to the honeycomb support frame 3.

[0047] Moreover, the compression plate 8 and the reinforcing layer 9 on the inner wall of the honeycomb support frame 3 work together through carbon fiber reinforced epoxy resin material. The compression plate 8 provides basic compressive strength, and the reinforcing layer 9, with its high strength and high modulus, further enhances the compressive performance of the honeycomb support frame 3, and together resist external pressure.

[0048] Under pressure, the auxiliary mechanism on one side of the fixed ring 2 is activated. The fixed cylinder 10 on one side of the fixed ring 2 and the fixed rod 11 slidably arranged inside form a sliding connection structure. When the honeycomb support frame 3 is subjected to pressure and produces a small displacement, the fixed rod 11 slides inside the fixed cylinder 10.

[0049] Furthermore, the multiple springs 12 sleeved on the surfaces of the fixing cylinder 10 and the fixing rod 11 between the fixing ring 2 and the honeycomb support frame 3 undergo elastic deformation when the honeycomb support frame 3 is displaced, generating a reverse elastic force to help the honeycomb support frame 3 return to its original position, playing a buffering and stabilizing role, and further enhancing the compressive strength of the aluminum profile.

[0050] Meanwhile, the surface of the aluminum profile body 1 is covered with a heat insulation layer 13 made of polyurethane foam. When the external temperature changes, the good heat insulation performance of the layer prevents heat from being transferred to the interior of the aluminum profile body 1, thus playing a role in heat insulation and protecting the internal structure of the aluminum profile from the influence of temperature changes.

[0051] Secondly, the surface of the heat insulation layer 13 is made of a wear-resistant coating 14 made of ceramic coating material. When the aluminum profile is subjected to friction, its high hardness and wear resistance protect the aluminum profile body 1 from wear and extend the service life of the aluminum profile.

[0052] In addition, the surface of the wear-resistant coating 14 is made of a waterproof layer 15 made of silicone coating material, which forms a waterproof barrier when it comes into contact with water or a humid environment, preventing moisture from penetrating into the interior of the aluminum profile body 1, preventing the aluminum profile from rusting and corroding, and further enhancing the durability of the aluminum profile.

[0053] Multiple equilateral triangular weight-reduction holes 16 are opened on the surface of the honeycomb support frame 3. Without affecting the overall structural strength, the weight of the aluminum profile is reduced by reducing the amount of material used, thus reducing the overall load. At the same time, the equilateral triangular shape design can ensure the stability of the structure and maintain the compressive strength of the aluminum profile while reducing weight.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
