The invention discloses an active falling-off type automobile front auxiliary frame control system, and relates to the technical field of vehicle chassis, the active falling-off type automobile front auxiliary frame control system comprises an air bag control unit, an ignition current transmission wire harness, a telescopic cylinder and a miniature gas generator, when an accident occurs, the air bag control unit sends out an explosion signal, a gas generating agent is exploded, and the miniature gas generator is started; the front cavity of the piston lock pin cylinder body is instantly filled with high-pressure gas, the piston lock pin moves backwards, under the action of the telescopic spring, the telescopic rod is unlocked, the front end of the front auxiliary frame actively falls off, the energy absorption space of a front cabin is increased, influences of low voltage are avoided, the safety of a passenger cabin is guaranteed, the survival rate of passengers in serious accidents is increased, and the problem that in the collision process, the safety of the passenger cabin is affected is solved. The technical problem that in the prior art, the energy absorption space of the front portion of a short front overhang new energy vehicle is insufficient is solved.
本发明公开了一种主动脱落式汽车前副车架控制系统,涉及车辆底盘技术领域,它包括:气囊控制单元、点火电流传输线束、伸缩缸、微型气体发生器,当事故发生后,气囊控制单元发出点爆信号,将气体发生剂点爆,高压气体瞬间充满活塞锁销缸体的前腔体,活塞锁销后移,在伸缩弹簧作用下,伸缩杆解锁,前副车架前端主动脱落,增加前机舱吸能空间,不受低压电的影响,保障乘员舱安全,提升严重事故中乘员生存率,增大乘员生存率,解决了在碰撞过程中,现有技术中短前悬新能源车型前部吸能空间不足的技术问题。
