The invention belongs to the technical field of new energy automobiles, and discloses a steel-aluminum composite material lower shell structure which comprises a sealing lining bottom plate, a left hanging assembly, a right hanging assembly, a front hanging assembly, a rear hanging assembly, a liquid cooling plate, a front cross beam, a middle cross beam, a rear cross beam, a front longitudinal beam and a rear longitudinal beam. The liquid cooling plate comprises a bottom plate and an upper sealing plate, the bottom plate is a steel plate and arranged on the inner side of the bottom of the sealing lining bottom plate, the upper side of the bottom plate is punched to form a cooling flow channel groove, the upper sealing plate is an aluminum plate and arranged on the upper side of the bottom plate, and the upper sealing plate and the cooling flow channel groove are sealed to form a cooling liquid flow channel. The liquid cooling plate is made of the steel-aluminum composite material, the upper-layer sealing plate is made of the aluminum plate, and the bottom plate is made of the steel plate, so that compared with a traditional aluminum liquid cooling plate, the liquid cooling plate made of the steel-aluminum composite material has higher strength and rigidity, the production cost in the aspects of labor and materials is saved, and the purpose of light weight of the lower shell can be achieved.
本发明属于新能源汽车技术领域,公开了一种钢铝复合材料下壳体结构,包括密封内衬底板、左侧挂载组件、右侧挂载组件、前部挂载组件、后部挂载组件、液冷板、前部横梁、中部横梁、后部横梁、前纵梁和后纵梁;液冷板包括底部板和上层密封板,底部板为钢制板,底部板设置在密封内衬底板的底部内侧上,底部板上侧冲压形成冷却流道槽,上层密封板为铝制板,上层密封板设置在底部板上侧,上层密封板与冷却流道槽之间密封形成冷却液流道。通过将液冷板采用钢铝复合材料,上层密封板为铝制板,底部板为钢制板,与传统铝制液冷板相比,钢铝复合材料的液冷板具有更高的强度与刚度,节约人工和材料方面的生产成本,而且能够实现下壳体轻量化的目的。
