Lower apron plate structure of lower-floor vehicle

The utility model relates to a lower apron plate structure of a lower-floor vehicle, which is characterized in that each of two sides of an aluminum honeycomb is adhered with an aluminum plate to form an apron plate; the periphery of the apron plate is adhered with plugging aluminum plates; the upper end of the upper plugging aluminum plate is connected with a hinge, and the lower end thereof is connected with an air spring mounting seat; and the lower part of the apron plate is further connected with another air spring mounting seat. The lower apron plate structure of the lower-floor vehicle has simpleness in structure and easiness in machining, and does not need special molds, thereby reducing the production design cost, shortening the manufacture period and satisfying the requirements of lower-floor vehicles with light weight.
