An automobile battery pallet assembly structure

Abstract

The invention provides an automobile battery supporting plate assembly structure, which comprises two parts, a left battery supporting plate assembly (1) and a right battery supporting plate assembly (2), the left battery supporting plate assembly (1) and the right The battery supporting plate assembly (2) is symmetrically arranged; the left battery supporting plate assembly (1) includes the left battery supporting plate subassembly (3), the left battery supporting plate beam structure assembly (4), the battery mounting beam assembly (5) and the left shock-absorbing gasket (6); the left battery support plate subassembly (3), the left battery support plate beam structure assembly (4), the battery installation beam assembly (5) and the left Shock gaskets (6) are overlapped successively. The automobile battery pallet assembly structure provided by the invention can securely fix the power battery group on the vehicle body under the vehicle body, and can better protect the battery group.

Description

technical field [0001] The invention relates to an assembly structure of an automobile battery tray. Background technique [0002] With the vigorous development of new energy vehicles, pure electric and hybrid vehicles have entered the public's field of vision. As an indispensable part of electric vehicles, the power battery pack has become the focus of the majority of automotive design engineers in the vehicle layout during the development of electric vehicles due to its large mass and volume and high requirements for the installation environment. [0003] Most of the early electric vehicles were remanufactured from fuel vehicles. Since the pure electric vehicle canceled the engine and its accessory system, the power battery pack was often arranged in the original fuel tank under the rear seat; the hybrid vehicle was often arranged in the rear luggage compartment. or under the underbody. The battery bracket is mostly in the form of a welded assembly combining metal beams,...

AI Technical Summary

Problems solved by technology

[0004] Since the battery pack of an electric vehicle generally weighs several hundred kilograms, the traditional layout method often leads to uneven distribution of axle loads on the front and rear axles, which adversely affects the handling and braking performance of the vehicle. The ground clearance increases the risk of scratches, and the battery bracket made of steel is not only heavy, but also needs anti-corrosion treatment. The layout of some models also has certain problems in terms of installation and maintenance convenience.
