The invention relates to a front torsion box structure of an electric automobile, and relates to the technical field of automobile design and manufacturing. The electric automobile front torsion box structure comprises a battery pack mounting cross beam, the two ends of the battery pack mounting cross beam are fixedly connected with a doorsill beam, front torsion box bodies are arranged on the lower portions of the two ends of the battery pack mounting cross beam, and each front torsion box body comprises a front longitudinal beam rear section, a front longitudinal beam rear section extending plate and a front auxiliary frame rear mounting plate; a closed cavity I is formed among the front longitudinal beam rear section, the front longitudinal beam rear section extension plate and the dash panel, and a closed cavity II is formed between the front longitudinal beam rear section extension plate and the dash panel; and two ends of the front auxiliary frame rear mounting plate are welded and fixed with the front coaming and the front longitudinal beam rear section. According to the front torsion box structure of the electric automobile, a stable triangular structure is formed, the occupied space is small, arrangement of a battery pack is not affected, extrusion to the battery pack after automobile body collision can be reduced, and safety of the battery pack is guaranteed.
本发明涉及一种电动汽车前扭力盒结构,涉及汽车设计和制造的技术领域。本发明的电动汽车前扭力盒结构包括电池包安装横梁,电池包安装横梁的两端与门槛梁固定连接,电池包安装横梁的两端下部设置有前扭力盒本体,前扭力盒本体包括前纵梁后段、前纵梁后段延伸板和前副车架后部安装板,前纵梁后段和前纵梁后段延伸板与前围板之间形成封闭腔I,前纵梁后段延伸板与前围板之间形成封闭腔II;前副车架后部安装板两端与前围板、前纵梁后段焊接固定。本发明的电动汽车前扭力盒结构构成了一个稳定的三角形构造,不仅占用空间小,不影响电池包的布置,而且能够减小车身碰撞后对电池包的挤压,保证电池包的安全。
