A body installation structure based on the front floor reinforcement beam structure of pure electric vehicles

Abstract

The invention discloses a car body installation structure based on a front floor reinforcement beam structure of a pure electric vehicle, comprising a first reinforcement beam and a second reinforcement beam located in front of the first reinforcement beam, parallel and symmetrically arranged on the left and right sides of the first reinforcement beam , the second reinforcing beam and the first reinforcing beam are fixed by reinforcing longitudinal beams perpendicular to the first reinforcing beam and the second reinforcing beam; the left and right sides of the first reinforcing beam and the second reinforcing beam are not fixed to the reinforcing longitudinal beam One side is connected with a longitudinal beam overlapping structure that can be fixed with the battery box installation longitudinal beam, and the top of the first reinforcing beam, the top of the reinforcing longitudinal beam and the top of the second reinforcing beam are all connected with a structure that can be overlapped with the front floor of the vehicle body. Front floor lap structure. The reinforced beam structure combined with the reinforced beam and the reinforced longitudinal beam designed by the present invention realizes the loading of front and rear segmented power batteries, effectively solves the problem of insufficient floor strength of the vehicle body, improves the safety performance of the side collision of the whole vehicle, and optimizes the load delivery path.

Description

technical field [0001] The invention relates to the technical field of pure electric vehicle body parts, in particular to a vehicle body installation structure based on a front floor reinforcement beam structure of a pure electric vehicle. Background technique [0002] At present, the lower body floor of some cars on the market has the defect of insufficient strength, especially pure electric vehicles. As a new energy vehicle, its driving power is mainly electric energy. Generally, power batteries need to be arranged under the front floor. The transmission space of the lateral load will reduce the side impact performance of the vehicle. How to strengthen the structural strength of the front floor of the lower body and optimize the transmission path of lateral load without affecting the installation of the power battery is the current problem. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies in the backgro...
