However, in actual environments with large temperature differences, hydraulic components are prone to failures such as shrinkage jamming and expansion leakage due to changes in the characteristics of the medium, resulting in the failure of the buffering performance. This seriously affects the reliability of the device and limits its application in extreme temperature scenarios. Summary of the Invention

The polarity of multiple secondary magnet groups is the same. The primary magnet and any secondary magnet group repel each other. The primary magnetic rod can move synchronously with the primary magnetic rod and gradually switch from the upper end of the second inner cylinder to the upper end of the second inner cylinder. The primary magnet drives multiple secondary magnetic units equipped with secondary magnet groups to move synchronously out of multiple second mounting slot units. The second outer cylinder is set outside the second inner cylinder and is arranged coaxially with the second inner cylinder.

[0013] The recoil buffer device and its array structure proposed in this invention have the following advantages: 1. The core components of a single buffer assembly work together to achieve efficient buffering with strong adaptability. The low-permeability, high-rigidity inner cylinder and the primary magnetic rod reduce magnetic energy loss and ensure structural stability; the inclined, non-penetrating mounting groove of the inner cylinder ensures a small gap between the primary and secondary magnetic rods to enhance magnetic repulsion while avoiding contact wear. The primary magnetic rod magnet and the secondary magnetic unit ring array work together to disperse the axial recoil force in the circumferential direction, and the energy is dissipated through the elastic connection structure.

[0014] 2. The array layout is flexible and synergistic, with buffering capacity expandable as needed. It supports radial tiling and axial series connection. Radially, adjacent component slots are connected via external connectors, while axially, the magnetic repulsion is superimposed by the opposing poles of the primary magnetic rods. The connecting blocks can be locked to ensure array stability, and the coplanar tops of the primary magnetic rods ensure synchronized force application. The layout and number of components can be adjusted according to load and space, adapting to both light-load, small equipment and heavy-load, large equipment, significantly broadening the application range and improving buffering stability and reliability under different operating conditions.
