The invention provides a torsion box structure, a vehicle body torsion beam and an electric vehicle, and belongs to the field of vehicles. The problem that in the prior art, a torsion beam cannot simultaneously absorb energy generated after front collision and side collision, and the energy absorption effect is poor is solved. The structure comprises three cavity structures, and a first cavity is formed by a torsion box front reinforcing plate, a front longitudinal beam lower reinforcing plate, a torsion box, a torsion box rear reinforcing plate, a doorsill inner plate, a front wall baffle lower plate and a front longitudinal beam outer plate. The front longitudinal beam inner plate, the front longitudinal beam rear plate, the front longitudinal beam rear reinforcing plate, the torsion box, the torsion box rear reinforcing plate, the front longitudinal beam lower reinforcing plate, the front longitudinal beam rear reinforcing plate, the threshold inner plate, the front wall middle lower plate and the front wall baffle lower plate form a second cavity; the front longitudinal beam rear reinforcing plate, the front longitudinal beam rear plate, the torsion box, the torsion box rear reinforcing plate and the front wall baffle lower plate form a third cavity. The system is mainly used for electric automobiles.
