Title:
ENERGY-ABSORBING CASING, CARRIAGE, AND RAIL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/284224
Kind Code:
A1
Abstract:
An energy-absorbing casing, a carriage, and a rail vehicle. The energy-absorbing casing comprises a casing body. The casing body comprises: a first-level energy-absorbing casing body (1), the cross-sectional area of the first-level energy-absorbing casing body (1) gradually increasing in the longitudinal direction, and the cavity wall of the first-level energy-absorbing casing body (1) from the center to the circumferential edge forming a smooth curved surface; and a circumferential casing body, the circumferential casing body being located at the rear end of the first-level energy-absorbing casing body (1), the circumferential casing body extending backwards in the longitudinal direction, and the cross-sectional area of the circumferential casing body gradually increasing in the longitudinal direction. The first-level energy-absorbing casing body (1) and the circumferential casing body form a hollow cavity having an open rear end to cover the front end of a vehicle body. The casing body forms a deformation energy-absorbing region by means of the first-level energy-absorbing casing body (1) and the circumferential casing body to cushion and absorb the impact of the vehicle body so as to eliminate the need for an energy-absorbing structure in the casing at the front end.
