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.

    本发明提出了一种扭力盒结构、车身扭力梁及电动汽车,属于汽车领域。解决了现有技术中扭力梁不能同时对正碰和侧碰后产生的能量吸收效果差的问题。它包括三个空腔结构,扭力盒前加强板、前纵梁下加强板、扭力盒、扭力盒后加强板、门槛内板、前围挡板下板与前纵梁外板形成第一空腔,前纵梁内板与前纵梁后板、前纵梁后加强板、扭力盒、扭力盒后加强板、前纵梁下加强板、前纵梁后加强板、门槛内板、前围中部下板以及前围挡板下板形成第二空腔,前纵梁后加强板、前纵梁后板、扭力盒以及扭力盒后加强板与前围挡板下板形成第三空腔。它主要用于电动汽车。
