The invention discloses a modularized telescopic chassis structure of an electric vehicle, which comprises a connector, a connecting rod, a connecting rod, a connecting rod, a connecting rod and a connecting rod, and is characterized in that the connecting rod comprises a connecting body cross beam and two connecting body longitudinal edge beams; the two connector longitudinal edge beams are symmetrically arranged, the two ends of the connector cross beam are fixedly connected with the two connector longitudinal edge beams respectively, and the connector cross beam is perpendicular to the connector longitudinal edge beams; the first telescopic body is arranged at one end of the connecting body and comprises a first telescopic body cross beam, a plurality of first telescopic body longitudinal beams, a first telescopic body cross edge beam and two first telescopic body longitudinal edge beams; the second telescopic body is arranged at the other end of the connecting body and comprises a second telescopic body cross beam, a plurality of second telescopic body longitudinal beams, a second telescopic body cross edge beam and two second telescopic body longitudinal edge beams; the first telescopic body longitudinal edge beam can slide in the axial direction of the connecting body longitudinal edge beam; the second telescopic body longitudinal edge beam can slide in the axial direction of the connecting body longitudinal edge beam. And the limiting and locking mechanism is used for limiting the positions of the first telescopic body and the second telescopic body relative to the connecting body.
