description The invention provides a lower automobile body structure and an automobile. The lower automobile body structure comprises two threshold beams which are oppositely arranged, a front floor and a cross beam assembly. The two side edges of the front floor are connected with the two threshold beams respectively. The cross beam assembly is installed on the front floor and comprises at least two vehicle body cross beams, and the two ends of each vehicle body cross beam are connected with the two threshold beams respectively; and a total force transmission path is formed between the two doorsill beams and the at least two vehicle body cross beams. A total force transmission path is formed between the two doorsill beams and the at least two vehicle body cross beams, so that collision force can be well decomposed and transmitted, the extrusion force on the lower vehicle body structure is weakened, the deformation of the lower vehicle body structure is reduced, and zero extrusion of the battery cell is guaranteed.
