Battery pack assembly for pure electric vehicle

Abstract

The invention, which belongs to the technical field of automobile manufacturing, discloses a battery pack assembly for a pure electric vehicle. The battery pack assembly comprises an upper shell and a lower shell, wherein the two shells are fixedly connected. The upper shell has a step-like structure. A first reinforced plate and a plurality of second reinforced plates are arranged at the outer side of the bottom surface of the lower shell; the first reinforced plate is arranged in the middle of the bottom of the lower shell and the two ends of the first reinforced plate approach the front end and the rear end of the lower shell; and the multiple second reinforced plates are distributed at the left side and the right side of the first reinforced plate symmetrically and are perpendicular to the first reinforced plate. A plurality of reinforced ribs are arranged at the outer side of the bottom of the lower shell. A third reinforced plate and a fourth reinforced plate that are parallel to the first reinforced plate are arranged at the left side and the right side of the lower shell; a fifth reinforced plate perpendicular to the first reinforced plate is arranged at the rear end of the lower shell. A plurality of second reinforced ribs are arranged on the fifth reinforced plate. The battery pack assembly has the excellent anti-vibration and anti-impact performances; fixed connection with an automobile body is realized; and the space utilization rate is high.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a battery pack assembly for pure electric vehicles. Background technique [0002] With the intensification of the energy and environmental crisis, it is particularly important to study an energy-saving and environmentally friendly vehicle that can alleviate energy pressure and reduce environmental pollution. Therefore, pure electric vehicles that replace traditional power sources with power batteries and drive motors have emerged as the times require One of the main development directions of industry. The power battery is the main source of power for pure electric vehicles and the core component of pure electric vehicles. [0003] The power battery is usually set in the battery pack and fixed on the car body through the battery pack. At present, the battery packs of pure electric vehicles are mostly fixed under the body floor. [0004] In the process of realiz...

AI Technical Summary

Problems solved by technology

Existing battery packs have poor strength and stiffness performance, and unreliable resistance to vibration and shock

This makes the battery pack not have enough carrying capacity and cannot withstand the gravity of the power battery. When the car is running, when the battery pack is subjected to vibration or impact load, the battery pack cannot be firmly connected to the body, which affects the safe driving of the car.
