Technical Field

[0001] This utility model relates to the field of lightweight aluminum body technology, specifically a high-strength lightweight aluminum body. Background Technology

[0002] Lightweight aluminum body refers to a lightweight body made of aluminum alloy materials. Aluminum alloy has a lower density, about 1 / 3 that of steel, which allows the aluminum alloy body to significantly reduce the weight of the vehicle, thereby improving fuel economy, handling, and range. The aim is to improve vehicle performance, reduce energy consumption, and enhance environmental benefits by reducing body weight. Automotive lightweighting must reduce the vehicle's curb weight as much as possible while ensuring vehicle strength and safety performance, effectively reducing fuel consumption. It has a high level of technical content, rather than simply reducing vehicle weight. Lightweight body makes steering more responsive, reduces the load on the suspension system, and makes the vehicle respond faster during acceleration, braking, and cornering, resulting in a lighter and more precise driving experience.

[0003] Based on existing solutions and actual production and processing, current lightweight aluminum car bodies still have some problems. For example, while using lightweight aluminum alloys to make car bodies brings many benefits, when a lightweight aluminum car body is impacted, due to the lower hardness and poor wear resistance of aluminum alloys, it may not provide the same level of protection as a steel car body. Therefore, this utility model provides a high-strength lightweight aluminum car body to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength, lightweight aluminum car body to address the problem mentioned in the background art that while lightweight aluminum alloys bring many benefits to automobiles, they may not provide the same level of protection as steel car bodies when impacted due to the lower hardness and poor wear resistance of aluminum alloys.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength lightweight aluminum car body, comprising an aluminum car body body with a reinforcing plate fixedly connected to the middle side inside it;

[0006] Also includes:

[0007] A limiting and fixing rod is movably installed on the lower inner side of the aluminum body body, and a mounting plate is movably connected to the outer side of the limiting and fixing rod. A mounting connecting plate is fixedly installed on the inner middle side of the mounting plate, and a mounting damper is fixedly installed on the inner middle side of the mounting connecting plate. A movable structure that plays a role in preventing collision is fixedly installed on the inner side of the mounting damper, and the buffer structure includes a movable block, a buffer anti-collision plate, a connecting spring, and a connecting movable rod.

[0008] Preferably, the aluminum body body includes an aluminum-silicon alloy layer, the upper side of which is connected to a 2A12 aluminum alloy layer, and an aluminum-copper alloy layer is installed on the upper side of the 2A12 aluminum alloy layer. The aluminum-copper alloy layer is internally connected to a reinforcing rib, and the upper side of the aluminum-copper alloy layer is connected to an aluminum-magnesium alloy layer, and the upper side of the aluminum-magnesium alloy layer is connected to an aluminum-manganese alloy layer.

[0009] Preferably, the reinforcing ribs are interlocked with the aluminum-copper alloy layer, and the reinforcing ribs are evenly distributed on the inner side of the aluminum-copper alloy layer.

[0010] Preferably, a high-strength support plate is also connected to the inner side of the upper end of the reinforcing plate, and a high-strength support block is fixedly connected to the middle side of the upper end of the high-strength support plate.

[0011] Preferably, the movable block is fixedly installed on the inner side of the damper, and a connecting spring is fixedly provided on the outer side of the movable block. A connecting rod is movably connected to the outer side of the movable block, and a buffer anti-collision plate that plays an anti-collision role is connected to the outer side of the connecting rod.

[0012] Preferably, the movable block and the mounting connecting plate are telescopically slidingly connected, and the movable block and the connecting movable rod are rotatably connected.

[0013] Preferably, the connecting rod is rotatably connected to the buffer anti-collision plate and provides a buffering effect for the buffer anti-collision plate.

[0014] Preferably, the high-strength support plate and the reinforcing plate are fixedly connected by welding, and the vertical cross-section between the high-strength support plate and the high-strength support block forms an inclined "T" shape structure, and the high-strength support block provides support for the reinforcing plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the high-strength lightweight aluminum car body is equipped with a buffer structure, which can protect the car body when it is hit, and is also equipped with high-strength support blocks, which can support the car body at the bends, thereby improving the strength of the car body.

[0016] 1. When the buffer crash plate is impacted, it moves inward inside the mounting plate, causing the buffer crash plate to rotate the connecting rod. This causes the moving block, which is connected to the connecting rod, to slide inside the mounting plate. The moving block then compresses the mounting damper and the connecting spring, thus providing protection when the aluminum car body is impacted.

[0017] 2. The reinforcing plate installed on the middle side inside the aluminum body body helps to improve the strength of the aluminum body body. Then, the high-strength support plate and high-strength support block are welded and fixed to support the bend of the reinforcing plate, thereby further improving the strength of the aluminum body body.

[0018] 3. The 2A12 aluminum alloy layer and aluminum-copper alloy layer connected to the upper side of the aluminum-silicon alloy layer can improve the strength of the aluminum body body. The aluminum-magnesium alloy layer and aluminum-manganese alloy layer connected to the upper side of the aluminum-copper alloy layer can further improve the strength of the aluminum body body. The reinforcing ribs installed inside the aluminum-copper alloy layer can further improve the strength of the aluminum body body. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1-5This utility model provides a technical solution: a high-strength lightweight aluminum car body, comprising: an aluminum car body body 1, an aluminum-silicon alloy layer 101, a 2A12 aluminum alloy layer 102, an aluminum-copper alloy layer 103, reinforcing ribs 104, an aluminum-magnesium alloy layer 105, an aluminum-manganese alloy layer 106, a reinforcing plate 2, a mounting plate 3, a movable block 4, a mounting connecting plate 5, a buffer anti-collision plate 6, a limiting fixing rod 7, a mounting damper 8, a connecting spring 9, a connecting movable rod 10, a high-strength support plate 11, and a high-strength support block 12. In operation, the specific details are as follows... Figure 1 , Figure 3 and Figure 4 As shown, a reinforcing plate 2 is fixedly installed inside the aluminum body body 1 by welding. A high-strength support plate 11 is fixedly connected to the inner side of the upper end of the reinforcing plate 2. A high-strength support block 12 is fixedly connected to the middle side of the upper end of the high-strength support plate 11. The reinforcing plate 2 is placed inside the aluminum body body 1 using a tool, so that the reinforcing plate 2 is fitted and installed inside the aluminum body body 1. Then, the reinforcing plate 2 is welded to the inner side of the aluminum body body 1 using a welding tool. The high-strength support plate 11 is manually placed inside the upper end of the reinforcing plate 2. Under manual action, the high-strength support plate 11 drives the high-strength support block 12 to contact the upper bend of the reinforcing plate 2. Under the welding action of the welding tool, the high-strength support plate 11 is fixed to the upper inner side of the reinforcing plate 2. Then, under the fixed action of the high-strength support plate 11, the high-strength support block 12 supports the upper bend of the reinforcing plate 2. The reinforcing plate 2 supports the upper bend of the aluminum body body 1, thereby facilitating the improvement of the strength of the aluminum body body 1.

[0027] Specific examples Figure 1 , Figure 2 and Figure 3As shown, an installation plate 3 is connected to the outer side of the aluminum body body 1. A limiting fixing rod 7 is movably connected to the inner side of the installation plate 3. Multiple sets of installation connecting plates 5 are fixedly connected to the inner side of the installation plate 3. Installation dampers 8 are fixedly installed inside the multiple sets of installation connecting plates 5. When the buffer anti-collision plate 6 is impacted, it moves to the right inside the installation plate 3. Under the movement of the buffer anti-collision plate 6, the buffer anti-collision plate 6 drives the connecting movable rod 10 to rotate. Under the rotation of the connecting movable rod 10, the connecting movable rod 10 rotates inside the moving block 4. Under the rotation between the connecting movable rod 10 and the moving block 4, the moving block 4 slides outward inside the installation connecting plate 5. The action causes the moving block 4 to compress the mounting damper 8, and then the sliding action between the moving block 4 and the mounting connecting plate 5 causes the moving block 4 to compress the connecting spring 9, which facilitates the anti-collision of the aluminum body body 1. Then, by rotating the limiting fixing rod 7 installed inside the aluminum body body 1, the limiting fixing rod 7 is threaded inside the aluminum body body 1 under the action of rotation. Thus, under the thread action between the limiting fixing rod 7 and the aluminum body body 1, the limiting fixing rod 7 moves inward. Then, under the action of the moving limiting fixing rod 7, the limiting fixing rod 7 is separated from the inner side of the mounting plate 3. Then, the mounting plate 3 is manually pulled, and under the action of pulling, the mounting plate 3 is separated from the outer side of the aluminum body body 1, which facilitates the replacement of the mounting plate 3.

[0028] Specific examples Figure 1 , Figure 2 and Figure 5 As shown, the aluminum body body 1 is made of materials such as aluminum-silicon alloy layer 101 and 2A12 aluminum alloy layer 102, and aluminum-copper alloy layer 103 is installed on the upper side of the 2A12 aluminum alloy layer 102. The reinforcing rib 104 is movably connected to the inner side of the aluminum-copper alloy layer 103. The aluminum body body 1 is composed of materials such as aluminum-silicon alloy layer 101 and 2A12 aluminum alloy layer 102. The addition of silicon to the aluminum-silicon alloy layer 101 effectively reduces component weight and improves fuel economy while maintaining structural strength, thus increasing the strength of the aluminum body body 1. The 2A12 aluminum alloy layer 102 is then connected to the upper side of the aluminum-silicon alloy layer 102. The aluminum-copper alloy layer 103, aluminum-magnesium alloy layer 105, and aluminum-manganese alloy layer 106 are included. The aluminum-manganese alloy layer 106 enhances strength and corrosion resistance through the addition of manganese. The magnesium content in the aluminum-magnesium alloy is typically between 5% and 12%, and it may also contain other elements such as manganese. Therefore, it has significant advantages in lightweight applications, giving it high strength and good ductility, which can further improve the strength of the aluminum body body 1. Furthermore, the reinforcing ribs 104 installed inside the aluminum-copper alloy layer 103 can further enhance the strength of the aluminum body body 1, thereby improving the load-bearing capacity of the aluminum body body 1.
