The invention provides a high-strength automobile bottom plate with a light weight structure. The structure can be used on a light bus, a light truck, a light compartment cargo and a motor home. The automobile bottom plate is of a hollow plate structure, reinforcing ribs are arranged in the hollow plate, and the reinforcing ribs are in a criss-cross shape or a step shape or a honeycomb shape or a wave shape. The structure of the chassis is changed, the hollow bottom plate is used for replacing an auxiliary beam and compartment bottom structure of an original light passenger car, under the condition that the overall strength can meet the overall bearing requirement, the gravity center of the whole car is lowered, a safety system prompts, the height of an upper car body is lowered by about 200 mm, the weight of the whole car is lowered by about 200 kg, and meanwhile the manufacturing cost of the whole car is lowered; and the bottom plate is welded through a friction stir welding process, so that long-term energy consumption can be saved, and the practicability of the device is improved. The internal configuration can be installed on a reserved hole in the bottom plate, a nut of the reserved hole is achieved through a pressing rivet or pulling rivet or welding technology, the whole car mode is better, and a driver and passengers feel more comfortable.

    本发明提供一种高强度轻量结构汽车底板,本结构可以用在轻型客车、轻型卡车、轻型厢货和房车上面。所述汽车底板为中空板结构,所述中空板内部设有加强筋,加强筋为纵横交错状或阶梯状或蜂窝状或波浪状。本发明通过将车底盘结构改变,使用中空底板代替了原来轻客的副梁+厢底结构,在整体的强度可以满足整体承载需求的情况下,整车重心降低,安全系统提示,降低上车身高度200mm左右,降低整车重量约200公斤,同时降低整车造价,且底板是通过搅拌摩擦焊工艺焊接,可节约长期能耗,提高了装置的实用性。内配置可以安装在底板上预留的孔上,预留孔的螺母是采用压铆或拉铆或焊接工艺实现,整车模态更好,驾驶人员和乘坐人员更加舒适。
