[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] A linkage-type buffer support structure for a metal mechanical suspension, as shown in the attached instruction manual. Figure 1 , 4 As shown in Figures 5 and 6, including:

[0032] A fixed plate 6 is configured as a U-shaped plate. A fifth pivot shaft 7 and a sixth pivot shaft 8 are respectively installed at the top and bottom of the cavity of the U-shaped plate. All fixing pins are welded to the side walls of the fixed plate 6. A first rod group is rotatably mounted on the fifth pivot shaft 7. The first rod group includes a first connecting rod 1, on which a second connecting rod 2 and a third connecting rod 3 are rotatably mounted. A second rod group is rotatably mounted on the sixth pivot shaft 8. The second rod group includes a fourth connecting rod 4, on which a fifth connecting rod 5 is rotatably mounted. The first rod group and the second rod group are interconnected and linked through the second connecting rod 2 and the fifth connecting rod 5, forming a buffer support mechanism. A central circular hole is provided at the end of the third connecting rod 3 that is connected to the outside for an external connecting pin to pass through. This structure employs two sets of linkage systems that are hinged and interconnected via connecting rods. When the connecting end of the third connecting rod 3 is subjected to an external impact load, the impact force is transmitted through the first linkage and guided to the second linkage via the second connecting rod 2 and the fifth connecting rod 5, forming a multi-level, multi-directional force flow decomposition and transmission path. This linkage mechanism effectively disperses concentrated impact energy across multiple connecting rods and pivot points, avoiding stress concentration and thus achieving excellent buffering performance. Simultaneously, this design significantly enhances the stability and balance of the entire suspension system under dynamic loads, reduces the risk of structural deformation and fatigue damage, and significantly improves the service life and operational reliability of the mechanism.

[0033] As per the instruction manual Figure 3 , 4 As shown, one end of the first link 1 is rotatably connected to the fifth pivot shaft 7, and its other end is rotatably connected to one end of the third link 3 via the first pivot shaft 9. A second pivot shaft 10 is fixedly mounted on the body of the first link 1, and one end of the second link 2 is rotatably connected to the second pivot shaft 10. The first link 1, as the core load-bearing and transmission component, creates multiple independent kinematic pairs through its pivot shaft design at both ends and on its body. This layout allows for complex and coordinated relative movements between the first link 1, the second link 2, and the third link 3, thus providing a larger effective displacement stroke and more flexible lever arm variation. This not only significantly improves the adaptability of the buffering process, enabling the mechanism to cope with impacts of varying intensities, but also greatly reduces the stress level at individual hinge points by distributing the load to multiple connection points. This plays a crucial role in improving the fatigue strength of the structure, reducing wear, and extending the maintenance cycle of critical components. The other end of the second link 2 is fixedly mounted with a third pivot shaft 11; as per the appendix to the specification. Figure 2 , 5As shown in Figure 6, a fourth pivot shaft 12 is fixedly mounted on the body of the third link 3; one end of the fourth link 4 is rotatably connected to the sixth pivot shaft 8, and the other end is rotatably connected to the third pivot shaft 11; one end of the fifth link 5 is rotatably connected to the third pivot shaft 11, and the other end is rotatably connected to the fourth pivot shaft 12. The arrangement of the third pivot shaft 11 and the fourth pivot shaft 12 is key to realizing the dynamic coupling between the first and second link groups. The fourth link 4 and the fifth link 5 share the third pivot shaft 11 as a common fulcrum. When an external impact acts on the third link 3, the impact force is decomposed and transmitted in multiple stages and directions through multiple links and pivot shafts. This linkage mechanism effectively disperses concentrated impact energy, avoids stress concentration, and achieves excellent buffering performance. At the same time, this design enhances the stability and balance of the suspension system under dynamic loads, significantly improving service life and operational reliability.

[0034] Each pivot axis is a damped pivot axis, which together converts the impact energy into a damping torque for the coordinated movement of multiple links, thereby achieving smooth and efficient buffering and energy dissipation, effectively avoiding hard-on rigid impacts and subsequent swaying.

[0035] As per the instruction manual Figure 1 , 2 As shown, both ends of the first link 1, the second link 2, the fourth link 4, and the fifth link 5, as well as one end of the third link 3, are all configured with annular connectors. The annular connectors facilitate rotational connection, reduce friction and wear, extend service life, and simplify the assembly process, thereby improving production efficiency and economy. The fixing plate 6, the first link 1, the second link 2, the third link 3, the fourth link 4, and the fifth link 5 are all made of high-carbon steel or alloy steel. High-carbon steel or alloy steel has high strength and wear resistance, can withstand heavy loads and repeated impacts, ensures the durability and safety of the structure, extends the overall service life, and is suitable for harsh working environments.

[0036] In the specific implementation of this embodiment:

[0037] This invention utilizes a linkage design between the first and second linkage groups. When an external impact load acts on the connecting pin at the end of the third link 3, the force is transmitted and decomposed through multiple links and pivots. Specifically, the third link 3 drives the first link 1 to rotate around the fifth pivot 7 via the first pivot 9. Simultaneously, the fourth pivot 12 on the third link 3 transmits motion through the fifth link 5. The first link 1 then drives the second link 2 via the second pivot 10, and the third pivot 11 at the end of the second link 2 pulls the fourth link 4 to swing around the sixth pivot 8. Each pivot is a damping pivot, collectively converting the impact energy into a damping torque for the coordinated movement of multiple links, thereby achieving smooth and efficient buffering and energy dissipation. This series of linkages forms a multi-degree-of-freedom micro-motion structure, which can effectively disperse and dissipate concentrated impact energy into the relative motion and friction of each component, thus providing a very smooth buffering effect and significantly improving the comfort and stability of the suspension system.

[0038] Furthermore, all connecting rod components of this invention have a regular structure and simple shape, making them very easy to machine and mass-produce. At the same time, both ends of the first, second, fourth, and fifth connecting rods, as well as one end of the third connecting rod 3, all use standardized circular connectors. This unified design greatly simplifies the assembly process and makes subsequent maintenance or replacement of any individual component very convenient, effectively reducing the maintenance cost throughout the entire lifecycle.

[0039] Unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
