Power battery pack assembly rear protection structure and new energy vehicles

Abstract

The invention provides a rear end protection structure of a power battery pack assembly and a new energy vehicle. The rear end protection structure of the power battery pack assembly of the present invention is used to protect the rear end of the power battery pack assembly, and includes a The structural body composed of the upper guard plate and the lower guard plate, which are fastened together up and down, is configured with a plurality of first connecting parts to connect with the power battery pack assembly on one side of the structural body, and is relatively The first connecting portion is configured with a plurality of second connecting portions on the other side of the structural body for connecting with the rear subframe assembly of the vehicle carrying the power battery pack assembly. The protection structure for the rear end of the power battery pack assembly according to the present invention can protect the rear end of the power battery pack assembly, and can reduce the probability of damage to the rear end of the power battery pack assembly.

Description

Technical field [0001] The present invention relates to the field of new energy vehicles, and in particular, to a power battery pack assembly rear end protective structure for power battery pack assemblies in new energy vehicles, and the present invention also relates to a total of the power battery pack. New energy vehicle in the back-end protective structure. Background technique [0002] With the development of power battery technology, new energy vehicles with power batteries are increasingly attached to people, and the technical research and development of new energy vehicles has become an important part of various car companies. The power battery pack assembly in the new energy vehicle is generally located under the body floor, and the protection of the battery pack body and related electrical components of the power battery pack assembly is not specially protected, or wrapped in a plastic shift plate. Single-layer steel sheet protection and the use of battery pack guard be...

AI Technical Summary

Problems solved by technology

[0003] Among the above protection forms, the wrapping method of the plastic guard plate is complex in structure, and the effect of waterproof and anti-collision is poor. The single-layer steel plate can play a certain protective role, but its effect is average. Avoid damage to the structure of the battery pack body, but it also has the disadvantage of not being able to form a full coverage protection

For new energy vehicles, if there is no protective structure at the rear end of the power battery assembly, or the protective structure used is not effective, it is obvious that the daily use of new energy vehicles, especially in the working conditions of car drop, pile passing, curb impact, etc. In this case, it is easy to cause damage to the relevant structure at the rear end of the power battery pack assembly, which will affect the normal use of the vehicle.
