The invention relates to an automobile frame structure. The structure comprises a front anti-collision beam, an energy absorption box, an upper longitudinal beam, a longitudinal beam, a damping towertop bracket, a side beam and a hinge column, wherein the front anti-collision beam, the energy absorption box and the longitudinal beam are connected in sequence; the upper longitudinal beam and the side beam are connected with the hinge column respectively. The structure also comprises an auxiliary energy absorption box and a front cabin reinforcing cross beam. The auxiliary energy absorption boxis connected with the front anti-collision beam and transmits collision force to the upper longitudinal beam, and the upper longitudinal beam transmits the collision force to the non-collision side through the damping tower top bracket and the front cabin reinforcing cross beam in sequence. Compared with the prior art, the weight of the whole vehicle is reduced, meanwhile, the collision safety performance and the torsional rigidity of the whole vehicle are improved, the production and manufacturing cost of a main engine plant is reduced, and then the fuel economy of a traditional vehicle andthe endurance mileage of a new energy vehicle are improved.
本发明涉及一种汽车框架结构,包括前防撞梁、吸能盒、上纵梁、纵梁、减震塔顶支架、边梁和铰链柱,所述前防撞梁、吸能盒和纵梁依次连接,所述上纵梁和边梁分别与铰链柱连接,还包括副吸能盒和前舱加强横梁,所述副吸能盒与前防撞梁连接,并将撞击力传递给上纵梁,所述上纵梁依次通过减震塔顶支架和前舱加强横梁将撞击力传递至非撞击侧。与现有技术相比,减低整车重量的同时提高碰撞安全性能和整车扭转刚度,也降低主机厂的生产制造成本,进而提高了传统车的燃油经济性和新能源汽车的续航里程。
