Abstract

The invention relates to a power battery installing structure, and belongs to the technical field of automobile design and manufacturing. The power battery installing structure comprises a rear floor,a left rear longitudinal beam, a right rear longitudinal beam, a power battery installing plate, a power battery reinforcement plate, and a rear floor lower cross beam, wherein the left rear longitudinal beam and the right rear longitudinal beam are arranged on the two sides of the rear floor, and the rear floor lower cross beam is arranged below the rear floor. The left side of the rear floor lower cross beam is welded with the left rear longitudinal beam, the right side of the rear floor lower longitudinal beam is welded with the right rear longitudinal beam, and the upper surface of the rear floor lower cross beam is welded with the rear floor and then forms a closed cross section structure with the rear floor. The bottom of the power battery installing plate and the bottom of the power battery reinforcement plate are welded to the rear floor lower cross beam, and the top of the power battery installing plate and the top of the power battery reinforcement plate are fixedly connected through a bolt and a nut.

Description

technical field [0001] The invention relates to the technical field of automobile design and manufacture, and more specifically, the invention relates to a power battery installation structure. Background technique [0002] With the gradual increase of people's awareness of environmental protection and the support of national industrial policies, electric vehicles are gradually being promoted and applied. In order to ensure a large cruising range, electric vehicles need to install a large number of power batteries. In order to meet the installation reliability of the power batteries, the installation points of the batteries need to meet high strength and rigidity requirements. The designed installation structure must be able to meet the installation requirements of the power battery. Because battery modules are of regular shape, power batteries are generally of regular shape. At the rear of the power battery, affected by the shape of the battery and the suspension of the r...
