Embodiments of the present application provide a double-layer underframe, comprising a lower-layer underframe composed of a lower-layer underframe middle module and a lower-layer underframe end module which are connected to each other, the position of the lower-layer underframe middle module being lower than that of the lower-layer underframe end module; and an upper-layer underframe composed of an upper-layer underframe middle module and an upper-layer underframe end module which are connected to each other. A modular design is used for all parts of the double-layer underframe, so that the double-layer underframe is simple and convenient to maintain, and flexible and diverse in use. A vehicle body using the double-layer underframe can be divided into two layers for carrying passengers, so that the passenger capacity is increased.
