Document Type and Number:
WIPO Patent Application WO/2023/000513
Kind Code:
A1
Abstract:
An aluminum alloy subway car body profile capable of combination, comprising a roof profile, an upper side beam profile, a side wall profile, a lower side beam profile, and a floor profile. The roof profile comprises two wide roof side profiles (3a, 3b) to adapt to an A-type car and a B-type car, respectively. The upper side beam profile comprises a drum-shaped car upper side beam (4a) and a trapezoidal car side beam (4b) to adapt to a drum-shaped car and a trapezoidal car, respectively. The side wall profile comprises a drum-shaped car side wall middle section bar (7a) and a trapezoidal car side wall middle section bar (7b) to respectively adapt to the drum-shaped car and the trapezoidal car. The lower side beam profile comprises a drum-shaped car lower side beam (9a) and a trapezoidal car lower side beam (9b) to respectively adapt to the drum-shaped car and the trapezoidal car. The floor profile comprises bottom frame side profiles (10a, 10b) of two widths to adapt to the A-type car and the B-type car, respectively. By means of optimizing the profile design of the car body profile, the rate of common use among profiles is increased, the profile can be compatible with various car types, and only 17 profiles are used to construct a section of a car body of an A-type trapezoidal car, an A-type drum-shaped car, a B-type trapezoidal car and a B-type drum-shaped car.
