Embodiment
[0037] On the premise of structural reliability, the present invention realizes a large order of magnitude increase in the buffer space through the expansion and contraction of the compartment wall, and increases the absorption of impact energy through the deformation of the damping material block in the compartment wall and the compartment module wall.
[0038] Such as Figure 1-3 As shown, the present invention provides a multi-stage active extension train anti-collision buffer structure, which is used in the case of rail transit trains colliding. The first car is connected as Figure 6 As shown, it includes a first-level anti-collision buffer module 6 and a plurality of secondary anti-collision buffer modules that are sequentially retractable through multiple stages. The first-level anti-collision buffer module 6 is connected to the front 4, and the last secondary anti-collision buffer module Connected with the first compartment, the size of each secondary anti-collision b...
