The invention discloses a wheel base-variable battery pack and frame integrated structure, and relates to the field of frames. The battery pack and frame integrated structure with the variable wheelbase comprises two middle longitudinal beams, two rear longitudinal beams, driving devices and a battery pack, wherein the two rear longitudinal beams can move in the length directions of the middle longitudinal beams respectively; the driving devices are used for driving the two rear longitudinal beams to move in the length directions of the corresponding middle longitudinal beams respectively; the two ends of the battery pack are connected with the two middle longitudinal beams respectively; the driving device comprises a driving motor, a gear connected with an output shaft of the driving motor and a rack correspondingly meshed with the gear, and the middle longitudinal beam and the corresponding rear longitudinal beam are connected with one of the rotatable gear and the corresponding rack respectively. According to the wheel base-variable battery pack and frame integrated structure provided by the invention, a wheel base-variable structure can be realized on the premise that the connection stability of the battery pack and the longitudinal beam is not reduced.
