WIPO Patent Application WO/2023/246684

A1

Disclosed in the present invention are an energy-absorbing buffer stop for a train, and a stopping and energy absorption method. The buffer stop comprises a fixed wall mounted on a track, a movable wall mounted on the track, main energy-absorbing elements, a coupler portion, and an anti-climbing portion; a plurality of movable legs capable of sliding backwards along the track are provided below the main energy-absorbing elements, and the movable legs are located between the movable wall and the fixed wall; the coupler portion penetrates through the movable wall, an energy-absorbing element is provided inside the portion of the coupler portion located behind the movable wall, and at least part of the energy-absorbing element is located between the movable wall and the fixed wall. According to the present invention, the coupler portion is added as an energy-absorbing element, such that an effective energy absorption stroke of the buffer stop is increased, and the collision safety performance of trains is improved.
