The invention relates to an electric vehicle undercarriage and an electric vehicle. The electric vehicle undercarriage comprises a transmission mechanism, an expansion and contraction mechanism and a Macpherson suspension system, wherein the transmission mechanism is used for converting rotation motion input by a pedal plate of the electric vehicle to vertical motion output by an output end of the transmission mechanism; the upper end of the expansion and contraction mechanism is connected with the output end of the transmission mechanism; the expansion and contraction mechanism comprises an expansion position and a contraction position; the expansion and contraction mechanism is switched circularly between the expansion position and the contraction position in sequence, driven by the output end of the transmission mechanism; the Macpherson suspension system is connected with the lower end of the expansion and contraction mechanism; and the expansion and contraction mechanism supports the Macpherson suspension system on the ground through the switching from the expansion position to the contraction position, and allows the Macpherson suspension system to be separated from the ground through the switching from the expansion position to the contraction position. The electric vehicle undercarriage solves the problem that the electric vehicle is difficult to park in a harsh environment; safe parking of the electric vehicle can be realized; and the electric vehicle can still travel conveniently in the harsh environment.
