Abstract

The invention discloses a new energy electric vehicle rear floor framework assembly which is characterized by comprising a middle rear floor connecting plate, a rear floor framework left longitudinal beam assembly and a rear floor framework right longitudinal beam assembly which are fixedly connected to the two ends of the middle rear floor connecting plate and are symmetrically arranged relative to the central axis of a vehicle, and a rear floor front cross beam and a middle longitudinal beam assembly which are connected between the rear floor framework left longitudinal beam assembly and the rear floor framework right longitudinal beam assembly; according to the new energy electric vehicle rear floor framework assembly , the strength of the rear floor framework is enhanced, the collision performance of the tail of the vehicle is improved, and damage to the battery in the trunk at the tail is reduced.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and more specifically relates to a rear floor frame assembly of a new energy electric vehicle. Background technique [0002] Due to the continuous development of new energy electric vehicles, consumers have continuously increased requirements for the mileage of electric vehicles. Under the constraints of existing technologies, before there is a major breakthrough in battery research and development technology, the only way to increase battery capacity or increase the number of spare batteries is by increasing the battery volume. To increase battery capacity and mileage. However, the method of increasing the battery capacity by increasing the battery volume can easily lead to a continuous use of a battery, excessive heat generation, or when charging a battery, it takes longer to fully charge, which is not conducive to battery use. Safety and battery life preservation. Therefore, the most feasibl...
