The invention relates to a vehicle chassis structure for installing a battery pack on a platform, which comprises a vehicle body chassis assembly comprising a left doorsill longitudinal beam and a right doorsill longitudinal beam which are parallel to each other and arranged at an interval, and a vehicle body front floor and a dash panel lower cross beam which are fixedly connected between the left doorsill longitudinal beam and the right doorsill longitudinal beam; the battery pack installation assembly comprises a bolt hole located in the front wall plate lower cross beam, a battery pack front installation support connected to the front wall plate lower cross beam and a battery pack side installation beam connected to the automobile body front floor, and the bolt hole is used for detachably installing a first battery pack; and the battery pack front mounting bracket and the battery pack side mounting beam are used for detachably mounting a second battery pack together. According to the invention, the battery pack front mounting bracket and the battery pack side mounting beam are added or canceled on the vehicle body chassis assembly, so that the battery packs of different vehicle types can be switched and mounted, the difference between a pure electric vehicle and a hybrid electric vehicle is effectively reduced, and the part management difficulty and the production switching requirement are reduced.
本申请涉及一种平台化安装电池包的车辆底盘结构,包括:车身底盘总成,其包括相互平行且间隔设置的左门槛纵梁和右门槛纵梁,固定连接在左门槛纵梁和右门槛纵梁之间的车身前地板和前围板下横梁;电池包安装组件,其包括位于前围板下横梁上的螺栓孔和连接在前围板下横梁上的电池包前安装支架,以及连接在车身前地板上的电池包侧安装梁,螺栓孔用于可拆卸安装第一电池包,电池包前安装支架和电池包侧安装梁用于共同可拆卸安装第二电池包。本申请通过在车身底盘总成上增加或取消安装电池包前安装支架和电池包侧安装梁即可切换安装不同车型的电池包,有效的减少纯电动汽车与混合动力汽车的差异,降低了零部件管理难度及生产切换的要求。
