Description

Technical Field

[0001] The utility model relates to the technical field of automobile frames, specifically a lightweight high-strength aluminum tube frame for automobiles. Background Technique

[0002] In modern automotive engineering, lightweighting is an important design trend aimed at improving the fuel efficiency and performance of vehicles. However, lightweighting does not mean sacrificing the strength and safety of the vehicle. Traditional automobile frames, especially the hood part, are usually made of heavier steel, which, although providing good structural strength, also increases the overall weight of the vehicle. This weight not only affects fuel economy but also the handling and response speed of the vehicle.

[0003] In addition, traditional automobile frame designs often perform poorly in terms of sound insulation and shock absorption, resulting in greater noise and vibration during driving, which affects driving comfort and the passenger experience. This problem is more obvious especially when driving at high speeds or on bumpy roads. In view of this, we propose a lightweight high-strength aluminum tube frame for automobiles. Content of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a lightweight high-strength aluminum tube frame for automobiles.

The reinforcing tubes and the support tubes are fixed by welding. Sound insulation cotton is provided in the gap between the support tubes and the reinforcing tubes. Reinforcing wires are arranged horizontally and vertically in the sound insulation cotton, and the ends of the reinforcing wires are fixedly connected to the outer walls of the support tubes or the reinforcing tubes. A number of equally spaced convex strips are integrally formed on the inner ring walls of the reinforcing tubes and the support tubes.

[0007] As a preferred technical solution, it further includes a central disc located at the center of the four reinforcing tubes. The outer wall of the central disc is fixedly connected with a second connecting tube fixed to the end of the reinforcing tube.

[0008] As a preferred technical solution, the outer circumferential wall of the central disc is fixed with a first connecting tube fixedly connected to the middle of the support tube.

[0010] As a preferred technical solution, the ends of the first support tube and the second support tube are symmetrical on the outer wall of the reinforcing tube.

[0011] As a preferred technical solution, a reinforcing block is fixedly connected to the middle of the circumferential outer walls of the first support pipe and the second support pipe, and the reinforcing block is connected to the inner wall of the engine hood by rivets.

[0012] As a preferred technical solution, filling cotton is provided inside both the support pipe and the reinforcing pipe.

[0013] As a preferred technical solution, the support pipe, the reinforcing pipe, and the connecting pipe are all made of the same material.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0025] A lightweight automotive high-strength aluminum tube frame, including four reinforcing tubes 2 arranged in a circular array and a first support tube 1 arranged horizontally and a second support tube 3 arranged vertically fixed between two adjacent reinforcing tubes 2. The reinforcing tube 2 is fixedly welded to the support tube, and a sound insulation cotton 7 is provided in the gap between the support tube and the reinforcing tube 2. Reinforcing wires 70 are arranged in a horizontal and vertical cross pattern in the sound insulation cotton 7, and the ends of the reinforcing wires 70 are fixedly connected to the outer wall of the support tube or the reinforcing tube 2. A plurality of equally spaced convex strips 8 are integrally formed on the inner circumferential walls of the reinforcing tube 2 and the support tube. The lightweight automotive high-strength aluminum tube frame includes four reinforcing tubes 2 arranged in a circular array and the first support tube and the second support tube 3 fixed between adjacent reinforcing tubes 2. This structure is fixedly welded to enhance the overall stability of the frame. A sound insulation cotton 7 is provided in the gap between the support tube and the reinforcing tube 2, which not only improves the sound insulation effect of the vehicle, but also further enhances the stability of the frame through the reinforcing wires 70. The convex strips 8 integrally formed on the inner walls of the reinforcing tube 2 and the support tube enhance the structural strength of the tube, thereby improving the load-bearing capacity and impact resistance of the entire frame.

[0026] As a preference of this embodiment, it further includes a central disk 5 located at the center of the four reinforcing tubes 2, and a second connecting tube 51 fixedly connected to the outer wall of the central disk 5 and fixed to the end of the reinforcing tube 2. By introducing the central disk 5 located at the center of the four reinforcing tubes 2 and fixing the central disk 5 to the end of the reinforcing tube 2 through the second connecting tube 51, the structure of the entire frame becomes more compact and stable. The central disk 5 serves as a connection hub, effectively dispersing and bearing the stress and impact from all directions, thereby enhancing the overall strength and rigidity of the frame.

[0027] As a preference of this embodiment, a first connecting tube 50 fixedly connected to the middle of the support tube is fixed to the circumferential outer wall of the central disk 5. By fixing the first connecting tube 50 to the circumferential outer wall of the central disk 5 and connecting it to the middle of the support tube, the stability and integrity of the frame are further enhanced. This connection method helps to effectively transfer the force received by the support tube to the central disk 5, and then the central disk 5 disperses it to the entire frame, thereby improving the load-bearing capacity and durability of the frame.

[0028] Preferably in this embodiment, a fixing head 6 is integrally formed at one end of the reinforcing pipe 2 away from the second connecting pipe 51, and a fixing hole 60 is formed in the fixing head 6. A fixing head 6 is integrally formed at one end of the reinforcing pipe 2 away from the second connecting pipe 51, and the fixing hole 60 formed in the fixing head 6 facilitates the fixed connection of the entire frame to other components or the vehicle body structure.

[0029] Preferably in this embodiment, the ends of the first support pipe 1 and the second support pipe 3 are symmetric on the outer wall of the reinforcing pipe 2. The ends of the first support pipe 1 and the second support pipe 3 are symmetrically arranged on the outer wall of the reinforcing pipe 2. This symmetrical structure helps to balance the forces received by the support pipes and prevent the frame from deforming or being damaged due to uneven forces. At the same time, the symmetry also helps to improve the aesthetics of the entire frame.

[0030] Preferably in this embodiment, a reinforcing block 4 is fixedly connected to the middle of the circumferential outer walls of the first support pipe 1 and the second support pipe 3, and the reinforcing block 4 is connected to the inner wall of the engine hood by rivets. Further enhances the stability and load-bearing capacity of the support pipes.

[0031] Preferably in this embodiment, filling cotton 9 is provided inside both the support pipes and the reinforcing pipe 2. It can increase the damping effect of the pipe materials, reduce the transmission of vibration and noise, and helps to improve the comfort and quietness of the vehicle.

[0032] Preferably in this embodiment, the support pipes, the reinforcing pipe 2, and the connecting pipes are all made of the same material. The support pipes, the reinforcing pipe 2, and the connecting pipes are made of the same material, ensuring the consistency of the material properties of the entire frame. This consistency helps to improve the overall performance and durability of the frame, and at the same time simplifies the production and maintenance processes.

[0033] When the lightweight automotive high-strength aluminum pipe frame of the present utility model is in use, the frame is composed of four reinforcing pipes 2 and the transverse first support pipes 1 and longitudinal second support pipes 3 fixed between them, forming a stable support structure. These pipe fittings are fixed by welding, and convex strips 8 are provided inside to enhance the structural strength.

[0034] To improve the sound insulation effect and stability, sound insulation cotton 7 containing reinforcing wires 70 is added to the gap between the support pipes and the reinforcing pipe 2. The central disc 5 connects all the reinforcing pipes 2, increasing the integrity and strength of the frame, enabling the frame to better disperse stress and impact.

[0035] Filling cotton 9 is provided inside the support pipes and the reinforcing pipe 2 to reduce vibration and noise. All the pipe fittings and connecting pipes are made of the same material, ensuring performance consistency.
