Abstract

The invention discloses an automobile body framework which comprises a front compartment framework, a battery pack compartment framework, a tail compartment framework and top cover beams. The rear end of the front compartment framework is fixedly connected with the front end of the battery pack compartment framework. The rear end of the battery pack compartment framework is fixedly connected with the front end of the tail compartment framework. The front end of each top cover beam is fixedly connected with the front compartment framework and the rear end of each top cover beam is fixedly connected with the tail compartment framework. A battery pack compartment front cross beam and a battery pack compartment rear cross beam are arranged in the middle rear portion of the battery pack compartment framework. Each of the two sides of the battery pack compartment framework is provided with an outer longitudinal beam and an inner longitudinal beam. The two ends of each outer longitudinal beam and the two ends of each inner longitudinal beam are fixedly connected with the battery pack compartment front cross beam and the battery pack compartment rear cross beam. Each inner longitudinal beam is located on the inner side of the corresponding outer longitudinal beam. One end of each inner longitudinal beam inclines towards one end of the corresponding outer longitudinal beam. An acute angle is formed between each inner longitudinal beam and the corresponding outer longitudinal beam. A fixing frame is formed by the inner longitudinal beams on the two sides, the battery pack compartment front cross beam and the battery pack compartment rear cross beam. The mass of a whole automobile is small, the arrangement optimization of a battery pack is guaranteed, and danger caused by collisions is avoided.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile body frame. technical background [0002] With the development of pure electric vehicle technology, the weight reduction of automobile body frame and the safety of body frame are increasingly valued by customers and automobile manufacturers. The quality of the car body frame affects the cruising range of pure electric vehicles. In order to improve the cruising range of pure electric vehicles, it is necessary not only to optimize the battery pack system, but also to make the vehicle lightweight. The body frame accounts for most of the mass of the vehicle, so making the car body frame lightweight becomes an important direction. At the same time, pure electric vehicles are equipped with battery packs, and the volume and quality of battery packs are relatively large, which will bring difficulties to body layout and structural design. Moreover, the battery pack is likely to ...
