Description

Technical Field

[0001] This utility model is a novel automotive metal swing arm, belonging to the field of automotive swing arm technology. Background Technology

[0002] It is a core component of the automotive suspension system, employing a double-arm frame structure and ball joint connection mechanism, and using the universal joint characteristics to control the up-and-down movement of the tires.

[0003] Most existing automotive control arms are solid, one-piece structures. Such structures increase weight and affect the vehicle's energy consumption. Therefore, while meeting strength requirements, we should minimize the amount of material used and reduce the impact of weight on the vehicle's energy consumption. Thus, a new type of automotive metal control arm is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of automotive metal swing arm to solve the existing problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel automotive metal swing arm, the structure of which includes a swing arm body, the two ends of the swing arm body being connecting ends, a cavity structure being provided between the two connecting ends, the cavity structure being opened inside the swing arm body, and a cover plate being provided on the top of the cavity structure, the cover plate being connected to the swing arm body by screws.

[0006] Furthermore, the cavity structure has a partition that divides the cavity structure into two connecting cavities and a reinforcing cavity, with the two connecting cavities located on one side of the two connecting ends, respectively.

[0007] Furthermore, each of the two connecting cavities has several reinforcing ribs distributed within it. The reinforcing ribs are in the shape of a straight strip and are made of high-strength aluminum alloy.

[0008] Furthermore, the spacing between the reinforcing ribs gradually increases, and the closer the reinforcing ribs are to the connection end, the closer the distance between them becomes.

[0009] Furthermore, a first filling cavity is provided between the two reinforcing ribs far from the connection end.

[0010] Furthermore, the reinforced cavity is provided with a reinforcing block, which is a triangular structure and there are two of them. One end of the two reinforcing blocks is connected to each other to form an hourglass shape.

[0011] Furthermore, the two reinforcing blocks and the inner cavity of the reinforcing cavity form a second filling cavity.

[0012] The beneficial effects of this utility model are:

[0013] The overall weight of the swing arm body is reduced by incorporating a cavity structure.

[0014] The hollow structure is equipped with reinforcing ribs and reinforcing blocks to ensure the strength of the swing arm body;

[0015] The cavity structure also has a filling cavity, which absorbs vibration energy and reduces fatigue damage by filling it with vibration-absorbing material;

[0016] It is equipped with a cover plate that can be opened, thereby allowing the cavity structure to be reinforced or improved. Attached Figure Description

[0017] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0018] Figure 1 This is a schematic diagram of the overall structure of a novel automotive metal swing arm according to this utility model;

[0019] Figure 2 This is a schematic diagram of the cavity structure of a novel automotive metal swing arm according to this utility model.

[0020] In the figure: swing arm body 1, connecting end 2, cavity structure 3, cover plate 4, connecting cavity 5, reinforcing cavity 6, reinforcing rib 7, first filling cavity 8, reinforcing block 9, second filling cavity 10. Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1 , Figure 2 This utility model provides a novel automotive metal swing arm technical solution: its structure includes a swing arm body 1, the two ends of the swing arm body 1 are connecting ends 2, a cavity structure 3 is provided between the two connecting ends 2, the cavity structure 3 is opened inside the swing arm body 1, and a cover plate 4 is provided on the top of the cavity structure 3, the cover plate 4 is connected to the swing arm body 1 by screws;

[0023] The cavity structure 3 has a partition that divides the cavity structure 3 into two connecting cavities 5 and a reinforcing cavity 6. The two connecting cavities 5 are located on one side of the two connecting ends 2, and each of the two connecting cavities 5 has several reinforcing ribs 7 distributed in a straight line. The spacing between the reinforcing ribs 7 gradually increases, and the closer the reinforcing ribs 7 are to the connecting ends 2, the closer the distance between them is. A first filling cavity 8 is provided between the two reinforcing ribs 7 that are away from the connecting ends 2.

[0024] The reinforcement cavity 6 is provided with reinforcement blocks 9. The reinforcement blocks 9 are triangular in structure and there are two of them. One end of the two reinforcement blocks 9 is connected to each other to form an hourglass shape. The two reinforcement blocks 9 and the inner cavity of the reinforcement cavity 6 form a second filling cavity 10.

[0025] For example, before installation, open the cover plate 4 and, depending on the vehicle conditions, choose to improve the cavity structure 3 or fill and replenish the first filling cavity 8 and the second filling cavity 10 with materials.

[0026] When the swing arm body 1 is in use, the reinforcing rib 7 provides strength support for the two connecting ends 2, and the reinforcing block 9 has a triangular structure. The triangle is the most stable structure in geometry, which can effectively disperse multi-directional stress and suppress deformation. The materials filled by the first filling cavity 8 and the second filling cavity 10 achieve vibration absorption and other effects.
