Abstract

The present invention provides a body structure and an automobile. The body structure includes a battery pack installation frame, a left threshold, a right threshold and a plurality of battery packs. The battery pack installation frame is fixedly connected between the left threshold and the right threshold. The battery pack installation frame includes a plurality of closed-loop beam structures, the inner side of the closed-loop beam structure forms a gap space, and each of the battery packs is arranged on the corresponding gap space; the battery pack includes a battery pack sealing cover and a battery pack. The tray, the battery pack sealing cover and the battery tray form a closed space for accommodating the battery module, and the top edges of the battery pack sealing covers of the plurality of battery packs are respectively connected to the inner side of the corresponding closed-loop beam structure and cover the Corresponding to the gap space to form the front floor. In the vehicle body structure of the present invention, when a battery pack fails, other battery packs can work normally, avoiding the risk that the vehicle cannot continue to run due to a sudden failure of a battery pack.

Description

technical field [0001] The invention belongs to the technical field of power battery installation, and in particular relates to a vehicle body structure and an automobile. Background technique [0002] The front floor of the existing automobile is usually a sheet metal panel structure, which is welded with the floor frame on the welding line to form an assembly. As a part of the body in white, it is an important part that constitutes the seal of the passenger compartment. [0003] Most of the existing electric vehicle battery pack sealing covers are made of composite materials or aluminum alloys. They are first assembled with battery trays and battery modules to form battery packs, and then supplied to the final assembly line for assembly with the vehicle body. The battery pack sealing cover is an important part of the battery pack seal. [0004] In the prior art, the front floor of the car and the sealing cover of the battery pack are two independent parts, and there is a ...
