Description

Technical Field

[0001] The present invention relates to the technical field of aluminum materials, and more specifically to an anti-deformation aluminum material for vehicles. Background Art

[0002] Cars are an important means of transportation in people's lives. As people's living standards continue to improve, the number of cars is increasing. Lightweight automobile manufacturing has become the main development trend in the current automobile manufacturing field. Aluminum, as one of the most widely used metal materials in the automobile manufacturing industry, is widely used in the modern automobile manufacturing industry for its advantages of light weight, low cost and high toughness. With the continuous improvement of aluminum performance, the quality of aluminum is constantly decreasing, and the coverage of aluminum in automobile parts is also expanding.

It is mainly used in the manufacture of engine covers, bumpers, wheels, engine assembly covers, muffler shells, heat exchangers, body floors, dashboards, seats and other parts. Since the gold content of deformed aluminum alloy is low, its toughness and strength will increase during the processing and forming process, so it has great performance advantages in the manufacturing process of wheel parts, heating systems, body panels, etc. In terms of body panel applications, heat-treated deformed aluminum alloys are often used to produce automobile frames and body panels, which can reduce the quality of body decorative parts and improve the stability of automobile movement. Therefore, deformed aluminum alloys are mainly used to manufacture suspension parts of automobile bodies.

It is easy to deform during installation and placement, and the surface is easily scratched, which affects the subsequent installation and use effects, and affects its performance and service life. When the vehicle is impacted, it is also easy to deform due to insufficient strength, and may even cause safety accidents. There are certain safety hazards.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The anti-deformation automotive aluminum material involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0026] The present invention provides an anti-deformation automotive aluminum material, please refer to Figure 1-5 As shown, it includes a reinforcing cross plate 3, a reinforcing support member 4, a cavity 5 and a buffer energy-absorbing component 6. The reinforcing cross plate 3, the reinforcing support member 4, the cavity 5 and the buffer energy-absorbing component 6 are formed into an aluminum body 2 by extrusion. Two reinforcing cross plates 3 are symmetrically arranged up and down. A buffer cavity 301 is opened in the reinforcing cross plate 3. A plurality of reinforcing support members 4 arranged at equal intervals are arranged in the buffer cavity 301. A cavity 5 is arranged on the opposite side of the two reinforcing cross plates 3. A plurality of groups of buffer energy-absorbing components 6 are arranged at equal intervals in the cavity 5, and the two reinforcing cross plates 3 are fixedly connected by the plurality of groups of buffer energy-absorbing components 6. The inner grooves in the reinforcing cross plate 3, the reinforcing support member 4, the cavity 5 and the buffer energy-absorbing component 6 are all rounded to avoid safety hazards caused by the sharp tips cutting the body of the staff during transportation and installation.

[0027] Furthermore, a bottom plate 1 is provided at the bottom of the aluminum body 2, the bottom surface of the bottom plate 1 is in contact with the ground, and the aluminum body 2 is placed on the top surface of the bottom plate 1, which is in contact with the ground, thereby preventing the surface of the aluminum body 2 from being scratched and damaged during transportation, preventing the aluminum body 2 from being deformed during transportation, ensuring the overall aesthetics of the aluminum body 2, and improving the transportation and storage quality of the aluminum body 2.

[0028] Furthermore, the aluminum body 2 includes an aluminum layer 201, an aluminum oxide layer 202, and an anodized layer 203. The weight of the aluminum layer 201 is more than 33% lighter than that of steel, while retaining most of its strength, being more tensile-resistant, and having a density two-thirds less than that of steel, making it the best substitute for other metal materials. The aluminum layer 201 is provided with an aluminum oxide layer 202 on the upper and lower surfaces, which can prevent the aluminum layer 201 from rusting and make the aluminum body 2 more corrosion-resistant. The aluminum oxide layer 202 is provided with an anodized layer 203 on the side away from the aluminum layer 201. An anodized layer 203 is provided, and a 25-micron anodizing treatment is performed on the outer surface of the aluminum body 2 to form the anodized layer 203, which can not only enhance the corrosion resistance of the aluminum body 2, but also improve the surface finish of the aluminum body 2, so that the aluminum body 2 does not need to be maintained, and in most cases there is no need to worry about corrosion. The aluminum body 2 made of the aluminum layer 201, the aluminum oxide layer 202 and the anodized layer 203 makes the automotive aluminum material lightweight, light and strong, durable, and reduces energy consumption.

[0029] It should be noted that the aluminum layer 201 is an AU-Cu-Mg alloy. During the heat treatment process, chemical elements such as manganese, copper and magnesium are added in appropriate amounts according to the hardness requirements of the aluminum material, so that in addition to the solid solution strengthening effect, it can also form strengthening stages such as 5CuA12 (one phase) and Al2CuMg (S phase). Among them, the addition of the chemical element manganese is mainly to improve the corrosion resistance of the aluminum layer 201, and it also has a certain solid solution strengthening effect. Since manganese has a small tendency to precipitate, it does not participate in the timely process. By controlling the addition of chemical elements copper and magnesium, the higher the copper and magnesium content in the aluminum layer 201, the more significant the timely strengthening effect and the higher the strength.

[0030] Specifically, the strength, formability and other properties of the aluminum body 2 can be adjusted by solution treatment and aging hardening treatment. The higher the temperature, the easier it is for the alloy elements added to the aluminum metal to melt. When heated to the inherent temperature of the alloy and then rapidly cooled, the alloy elements that should be precipitated at low temperature will be in a solid solution (dissolved) state. After the solution heat treatment, the alloy elements that could have been precipitated at low temperature will soon become forcedly melted after precipitating after rapid cooling, which is unstable. As time goes by, precipitation occurs in order to return to the original stable state. This precipitated crystal is not easy to slide and is relatively hard, so that the aluminum body 2 completes the aging hardening treatment. The strength, formability and other properties of the aluminum body 2 can be adjusted through cold processing, solution treatment, aging hardening treatment, annealing, etc.

[0031] Furthermore, the two ends of the reinforcing support member 4 are fixedly connected to the upper and lower inner walls of the buffer cavity 301 respectively, and a plurality of reinforcing support members 4 are interconnected to form a triangular stable structure in the buffer cavity 301. By arranging a plurality of reinforcing support members 4 in the buffer cavity 301, the strength of the aluminum body 2 is improved to avoid deformation. When the reinforcing cross plate 3 is impacted, the impact force is evenly dispersed by the reinforcing support members 4 in the buffer cavity 301 to prevent the reinforcing cross plate 3 from deformation.

[0032] Furthermore, the buffer energy absorption assembly 6 includes two relatively arranged buffer folding plates 601 and a plurality of energy absorption tubes 602. The plurality of energy absorption tubes 602 are fixedly connected between the two buffer folding plates 601, and two adjacent energy absorption tubes 602 are fixedly connected. The plurality of energy absorption tubes 602 are respectively fixedly connected to the bending parts of the buffer folding plates 601. When the reinforced cross plate 3 is impacted, the impact force is evenly dispersed by the reinforced support member 4 in the buffer cavity 301 to prevent the reinforced cross plate 3 from deformation. The dispersed force is absorbed by the buffer energy absorption assembly 6 arranged between the two reinforced cross plates 3.

[0033] Furthermore, the buffer folding plate 601 includes a connecting plate 6011 and an energy absorbing plate 6012. There are two connecting plates 6011. The energy absorbing plates 6012 are fixedly connected to the opposite ends of the two connecting plates 6011, and the other ends of the two connecting plates 6011 are respectively fixedly connected to two reinforcing cross plates 3. When the buffer energy absorbing component 6 is subjected to force, the connecting plates 6011 arranged in the buffer folding plate 601 will bend and squeeze to further absorb the impact force and prevent the aluminum body 2 from deformation.

[0034] Furthermore, several energy absorbing tubes 602 are provided with energy absorbing cavities 1 603, and several energy absorbing cavities 2 604 are formed between the buffer folding plate 601 and the energy absorbing tube 602. The energy absorbing cavities 1 603 and 604 can absorb impact energy, so that the energy absorbing cavities 1 603 and 604 can maintain strength and flexibility under load and rebound from the impact.

[0035] Furthermore, a slot 1 7 is provided on the left side of the cavity 5, and a block 1 8 is provided on the upper and lower sides of the slot 1 7, a block 2 10 is provided on the right side of the cavity 5, and a slot 2 9 is provided on the upper and lower sides of the block 2 10, the slot 1 7 is adapted to the block 2 10, and the block 1 8 is adapted to the slot 2 9, and by correspondingly connecting the slot 1 7 and the block 2 10 on the two adjacent aluminum bodies 2 respectively, and correspondingly connecting the block 1 8 and the slot 2 9 respectively, the area of ​​the automotive aluminum material can be adjusted, and preliminary fixation can be performed at the same time, which is convenient for welding during the subsequent installation process, avoiding displacement during the welding process, affecting the installation effect of the automotive aluminum material, making installation and welding more convenient, and thereby improving the installation efficiency of the automotive aluminum material.

[0036] The working principle of the present invention is as follows: firstly, the cross plate 3, the support member 4, the cavity 5 and the buffering energy absorbing component 6 are reinforced and formed into an aluminum body 2 through extrusion, and the aluminum body 2 is placed on the bottom plate 1 to prevent the surface of the aluminum body 2 from being scratched and damaged when the aluminum body 2 is transported, and to prevent the aluminum body 2 from being deformed during transportation. The aluminum oxide layer 202 can prevent the aluminum layer 201 from rusting and make the aluminum body 2 more corrosion-resistant, and an anodized layer 203 is formed on the outer surface of the aluminum body 2 at 25 microns, which can enhance the corrosion resistance of the aluminum body 2 and improve the surface finish of the aluminum body 2, so that the aluminum body 2 does not need maintenance. By correspondingly connecting the card slot 1 7 and the card block 2 10 on two adjacent aluminum bodies 2, the card Block 1 8 and slot 2 9 are respectively connected correspondingly, which can adjust the area of ​​the automotive aluminum material and perform preliminary fixation at the same time, so as to facilitate welding operations during the subsequent installation process and avoid displacement during the welding process. When the aluminum material body 2 is impacted, the impact force is first evenly dispersed through the reinforcing support member 4 in the buffer cavity 301 to prevent the aluminum material body 2 from deformation. The dispersed force is absorbed by the buffer energy absorption component 6 arranged between the two reinforcing cross plates 3. When the buffer energy absorption component 6 is subjected to force, the connecting plate 6011 arranged in the buffer folding plate 601 will bend and squeeze, and at the same time, the impact energy is absorbed through the energy absorption cavity 1 603 and the energy absorption cavity 2 604, so that it maintains strength and flexibility under load and rebounds from the impact, so that the automotive aluminum material can achieve the effect of anti-deformation.
