The invention relates to the technical field of automobile body frameworks, and provides an automobile body framework front structure. The automobile body framework front structure comprises a first force transmission channel, a second force transmission channel and a third force transmission channel. During collision, due to the adoption of the three kinds of force transmission channels, a bumper, an upper supporting beam, a front longitudinal beam and a front auxiliary frame can absorb collision energy through reasonable deformation and dissipate collision force, a first connecting plate, anautomobile body column A, a through connection body, a threshold beam and a middle channel beam can keep stability of a passenger compartment, the purpose of reducing passenger injuries is achieved,and safety performance is high. More importantly, floor longitudinal beams do not need to be adopted, the floor can be arranged to be a plane, the power battery does not need to be arranged in a narrow area between the floor longitudinal beams any more and is arranged on the wide plane of the floor, and then more power batteries can be arranged, and the endurance mileage of the pure electric vehicle is increased.
本发明涉及汽车车身骨架的技术领域,提供汽车车身骨架前部结构,包括第一传力通道、第二传力通道和第三传力通道。碰撞时,由于采用该三种传力通道,保险杠、上支承梁、前纵梁和前副车架能够通过合理变形来吸收碰撞能量,并将碰撞力耗散,而第一连接板、车身A柱、转接体、门槛梁和中通道梁能够保持乘员舱的稳定,达到减轻乘员伤害的目的,安全性能较高。更重要的是,其并不需要采用地板纵梁,地板可以设置为平面,动力电池无须再布置于地板纵梁之间的狭小区域,而设置在地板较宽广的平面上,从而可以设置更多的动力电池,提高纯电车的续航里程。
