Impact protection structure for battery pack and automobile

Abstract

The invention relates to the field of automobiles and provides an impact protection structure for a battery pack and an automobile. The impact protection structure comprises a battery pack storage space used for placing a battery pack and two longitudinal protection beams located on two outer sides of the battery pack storage space in the transverse direction, wherein the longitudinal protection beams extend in the longitudinal direction of the battery pack storage space and exceed the longitudinal outer end of the battery pack storage space; a primary anti-collision mechanism located on the outer side of the longitudinal outer end of the battery pack storage space is mounted on the longitudinal protection beams; a secondary anti-collision mechanism located between the primary anti-collision mechanism and the battery pack storage space is further mounted on the longitudinal protection beams. The automobile comprises the impact protection structure for the battery pack. The impact protection structure for the battery pack can better absorb energy after being collided to better protect the battery pack and to effectively reduce breakage of the battery pack, caused by squeezing deformation, or the probability of squeezing to damage peripheral components.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a battery pack impact protection structure and an automobile with the battery pack impact protection structure. Background technique [0002] New energy vehicles are an important direction for the development of automobiles today, and electric vehicles are an important part of them. In battery vehicles, a large part of the battery pack is rear-mounted, that is, located at the rear of the vehicle. For this type of electric vehicle, when receiving In a high-speed rear collision, the battery pack will be impacted and squeezed, resulting in serious deformation, resulting in dangers such as battery pack rupture, electrolyte leakage, battery fire, and explosion. Occupants are injured. Therefore, for electric vehicles with rear battery packs, it is important to consider the safety of battery packs in high-speed rear-end collisions. [0003] In the prior art, a primary honeycomb alu...

AI Technical Summary

Problems solved by technology

Specifically, when the rear of a car collides at high speed, the primary honeycomb aluminum structure cannot fully deform and absorb energy, so that the collision energy is directly transferred to the kinetic energy of the collided car; the protection of the battery pack cannot be achieved, and the battery pack can obtain a larger Acceleration and high-frequency vibration, and being squeezed, there are risks such as battery pack rupture, electrolyte leakage, battery fire and explosion; when the rear of the car collides at high speed, due to the insufficient performance of the anti-collision mechanism, it is easy to cause damage to the battery pack and the seat. The floor rails between them are deformed, causing the battery pack to collide with the rear seats, causing injury to the rear occupants
