Abstract

The invention belongs to the technical field of body frame, and relates to a body structure and an automobile. The body structure includes a battery pack installation frame and a battery pack fixedly connected to the battery pack installation frame. The battery pack installation frame includes a left door sill and a right door sill. Threshold, the battery pack includes a battery pack sealing cover and a battery tray, a closed space for accommodating battery modules is formed between the battery pack sealing cover and the battery tray, and the battery pack sealing cover is connected to the left threshold and the right threshold to form the front floor. The vehicle body structure of the present invention can increase the battery power of the battery pack, thereby improving the battery life of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of body frame, in particular to a 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 requirement for a matching gap betwe...
