Abstract

The invention provides a new energy vehicle body structure, comprising a lower body structure, wherein the lower body structure comprises: a first frame formed by a plurality of crisscrossed main beams connected with each other; and a second frame formed by a plurality of crisscrossed main beams connected with each other. The second frame is arranged at the periphery of the first frame. A plurality of supporting beams are connected between the second frame and the first frame, and a plurality of collapse deformation zones for transmitting impact force are formed between adjacent supporting beams and the main beams. A beam frame structure with a hollow square shape is arranged at the bottom of the lower body structure, a power battery is arranged on the inner ring of the hollow square shape, and the collision force can be gradually attenuated in the process of layer-by-layer transmission when collision occurs, so that the power battery is effectively protected.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a vehicle body structure. Background technique [0002] As one of the key components of new energy vehicles, power batteries can easily cause accidents such as combustion or explosion under certain conditions once they are hit. With the rapid development of new energy vehicles, how to effectively protect them has become an urgent problem to be solved. [0003] In the prior art, most of the power batteries are placed under the floor of the vehicle body, but there is no multi-layer beam structure for special protection, which greatly affects the safety performance of the vehicle body. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a new energy vehicle body structure that can effectively protect the power battery in view of the fact that the existing body structure does not protect the power battery suf...
