Abstract

The invention relates to a power battery arrangement and fixed connection structure, and belongs to the technical field of new energy automobiles. The power battery arrangement and fixed connection structure comprises power battery boxes; the power battery boxes comprise a battery front box and a battery rear box; the battery front box is arranged below a middle flour of an automobile body and located on the front side of a rear suspension of an automobile, and the battery rear box is arranged below a rear floor of the automobile body and is located on the rear side of the rear suspension of the automobile; and the battery front box and the battery rear box are fixed to the automobile body through a battery box frame beam. Compared with a conventional automobile, the automobile having the power battery arrangement and fixed connection structure disclosed by the invention has the advantages that the ride comfort is not affected, a luggage compartment space is not affected, and the purposes of high safety and superior handling stability are achieved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a power battery arrangement and a fixed connection structure. Background technique [0002] For pure electric vehicles, due to the large size and weight of the power battery, it has always been difficult to arrange them on the body. In addition, the increase in vehicle weight and short driving range have hindered its development and popularization. Pure electric vehicles are loaded with more power battery cells, which are bulky and heavy, so that the battery box assembly that fixes and seals the battery often has a large weight to meet the requirements of carrying the battery. In view of this, reducing the weight of the battery box assembly has become a measure to reduce the weight of the vehicle. Moreover, the existing power battery layout affects the ride comfort, the luggage space is not enough, and the safety and handling stability are poor. For the battery box,...
