[0002] As a key component of the automobile chassis system, the core function of the damping arm is to effectively suppress and reduce vibration to ensure the stable operation of the automobile. In the prior art, in order to improve the strength of the damping arm, a common method is to increase the weight, that is, to use thicker materials or to increase the structure size. Although this method enhances the carrying capacity of the structure to some extent, the increase in weight increases the overall weight of the system and may affect the energy efficiency of the vehicle, especially new energy vehicles. In addition, simply relying on increasing the weight of the material to improve the strength often leads to low utilization rate of the material, which not only increases the manufacturing cost, but also wastes resources due to material redundancy. Therefore, it is necessary to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0010] Optionally, the reinforcing rib is smoothly connected with the second supporting platform.
[0011] Optionally, the inner sides of the first plate part and the connecting plate part form an included angle of 120°.
[0012] Optionally, a plurality of guide posts are respectively formed on the first supporting platform and the second supporting platform, and all the guide posts extend in the same direction and have the same height.
[0013] Optionally, a plurality of through mounting holes are respectively formed on the first supporting platform and the second supporting platform, and at least one of the mounting holes is coaxially arranged with the guide post.

[0029] Please refer to Figures 1 to 6 A light-weight high-strength damping arm structure provided by the embodiment of the present application will be described. The light-weight high-strength damping arm structure comprises a first plate part 100, a connecting plate part 200 and a second plate part 300. Wherein:
[0030] The first plate part 100 forms a protruding first supporting platform 101; the connecting plate part 200 is connected to the side of the first plate part 100 away from the first supporting platform 101 and is flush with the first plate part 100, and a protruding three-pronged boss 201 is formed on the connecting plate part 200; the second plate part 300 is connected to the side of the connecting plate part 200 away from the first plate part 100, the thickness of the second plate part 300 is less than the thickness of the connecting plate part 200 and cooperates with the connecting plate part 200 to form a step 400, a protruding second supporting platform 301 is formed on the second plate part 300, the three-pronged boss 201 and the step 400 are arranged on the same side of the second plate part 300, the first supporting platform 101 and the second supporting platform 301 are arranged on the other side of the second plate part 300, and the end of the first supporting platform 101 away from the first plate part 100 and the end of the second supporting platform 301 away from the second plate part 300 are flush with each other. In the embodiment, the first plate part 100, the second plate part 300, the third plate part and other structures can be integrally formed by forging, so that the light-weight high-strength damping arm structure in the embodiment has higher structural strength. In addition, in order to achieve better light-weight design effect, the light-weight high-strength damping arm structure in the embodiment can also be made of high-strength aluminum alloy material and heat treated in T6 state to ensure the high strength of the damping arm.
[0031] According to the above structure provided in the embodiment, in the light-weight high-strength damping arm structure provided in the embodiment, the second plate part 300 with a thickness smaller than that of the connecting plate part 200 can significantly reduce the weight of the light-weight high-strength damping arm structure in the embodiment. Since the first supporting platform 101, the second supporting platform 301, the three-ridge boss 201, and the step 400 between the second plate part 300 and the connecting plate part 200 are arranged on opposite sides of the second plate part 300, and since the end of the first supporting platform 101 away from the first plate part 100 is flush with the end of the second supporting platform 301 away from the second plate part 300, the weight of the light-weight high-strength damping arm structure in the embodiment on both sides of the second plate part 300 is more balanced, and the overall gravity center of the light-weight high-strength damping arm structure in the embodiment is closer to or inside the body. Thus, the light-weight high-strength damping arm structure provided in the embodiment can have higher structural strength and bear greater mechanical load during use, which is much better than the prior art.
[0032] In another embodiment of the present application, referring to Figures 1 to 6 , the connecting plate part 200 is recessed to form a weight-reducing cavity 202; the sidewall of the connecting plate part 200 for forming the weight-reducing cavity 202 is arranged near the edge of the connecting plate part 200 to form a reinforcing rib 203 extending to the first plate part 100 and the second plate part 300 at both ends. According to the above structure provided in the embodiment, the weight-reducing cavity 202 formed on the connecting plate part 200 can not only effectively reduce the weight of the light-weight high-strength damping arm structure in the embodiment, but also form the reinforcing rib 203 connected to the first plate part 100 and the second plate part 300, which is conducive to further improving the structural strength of the light-weight high-strength damping arm structure in the embodiment.

[0035] In another embodiment of the present application, please refer to Figures 1 to 6 The first support platform 101 and the second support platform 301 are respectively provided with a plurality of guide columns 500. All the guide columns 500 extend in the same direction and have the same height.

Since all the guide columns 500 extend in the same direction and have the same height, the stress of the lightweight high-strength damping arm structure provided in the embodiment is more balanced, which is beneficial to further improve the structural strength of the lightweight high-strength damping arm structure provided in the embodiment.
[0036] In another embodiment of the present application, please refer to Figures 1 to 6 The first support platform 101 and the second support platform 301 are respectively provided with a plurality of through mounting holes 600, and at least one mounting hole 600 is coaxially arranged with the guide column 500.
