The invention relates to the technical field of electric vehicles, in particular to a lightweight chassis structure of a low-floor electric coach. The front part of a dual-carling chassis main structure is connected with a front axle saddle through a group of beams, a dual-swing arm front suspension assembly is positioned and assembled on the front axle saddle, after being assembled, the dual-swing arm front suspension assembly is positioned above a carling horizontal structure zone, the rear part of the dual-carling chassis main structure is connected with front support boxes and rear support boxes through two groups of beams, front and rear pivots of a plate spring type rear axle assembly are positioned and assembled on the front and rear support boxes, after being assembled, the plate spring type rear axle assembly is also positioned above the carling horizontal structure zone, and the carling horizontal structure zone can serve as the in-coach floor support surface. The chassis main structure is simple and safe, the front and rear axle assemblies are conveniently assembled, the workspaces are not interfered, the height of the in-coach floor and the coach door stepping height are obviously lowered, and thus the height of the coach is lowered, so that the comfort of getting on and off the coach and the trafficability of the coach can be improved.
