Abstract

The invention relates to the technical field of automobile structures, in particular to a power battery connecting structure. The power battery connecting structure comprises a battery module, a battery box body and a fastening plate, a first mounting hole and a second mounting hole are formed in the battery box body, and the battery module is provided with a connecting hole and fastening grooves.The connecting hole extends along the thickness direction of the battery module, the fastening grooves are respectively formed at the two opposite sides of the battery module, and the battery modulepenetrates through the connecting hole via bolts and is connected with the first mounting hole. The first end of the fastening plate is fastened with the fastening grooves, and the second end of the fastening plate is connected with the battery box body. The power battery connecting structure is simple, on one hand, the pre-tightening force is applied through the bolts, so that the battery moduleis tightly connected with the battery box body. In addition, the fastening grooves are formed at the two opposite sides of the battery module respectively, one end of the fastening plate is buckled with the corresponding fastening groove, and the other end of the fastening plate is connected with the battery box body, so that the displacement of the battery module due to inertia of the battery module in the automobile running process is limited, and the reliability and durability of the battery module installed in the battery box body are improved.

Description

technical field [0001] The invention relates to the technical field of automobile structures, in particular to a power battery connection structure. Background technique [0002] In the structural design of the new energy vehicle power battery system, the reliability and stability of the mechanical strength of the battery module installation is an important factor affecting the overall safety level of the power battery system. [0003] In the existing power battery system, the installation structure of the battery module is single, which cannot cope with the complex stress environment of the battery module during the driving process of the car, and the structural reliability and stability of the battery module are poor. Contents of the invention [0004] The purpose of the present invention is to provide a power battery connection structure that helps to improve the stability and reliability of battery module installation. [0005] In order to achieve the above object, th...
