Description
Technical Field
The invention belongs to the application technology of electric automobiles, and particularly relates to an installation structure of a power battery pack of an electric automobile.
Background
With the aggravation of energy and environmental pollution, it is very important to research an energy-saving and environment-friendly automobile capable of relieving energy pressure and reducing environmental pollution, and therefore, a pure electric automobile is in operation. The traditional automobile parts are numerous, the space for arranging the power battery is very limited under the condition that the structure of an automobile body is not greatly changed, the power battery pack of a pure electric automobile is placed in a front cabin or a trunk, and the two modes cause the load of a front axle or a rear axle of the automobile to be too high, so that the front axle and the rear axle are not uniform respectively. Because the battery pack has the characteristics of heavy weight, large volume, high temperature and the like, at present, most power batteries of the pure electric vehicle are arranged below a vehicle body floor, but the technical problems of how to arrange numerous and scattered battery monomers and how to design a battery pack structure, a vehicle body floor structure and a battery fixing point structure are faced; in addition, the battery is arranged in the floor below, takes the space and hardly compromises with ground clearance simultaneously, and the battery package space can not obtain make full use of more, and battery monomer is too diversified in groups, and the module is fixed difficult, and battery cooling difficulty, battery package are sealed difficult. The unreasonable structural design causes great servicing quality of the electric automobile, and is not favorable for the economical dynamic property of the electric automobile.
Disclosure of Invention
The invention provides an installation structure of a power battery pack of an electric automobile, aiming at the defects of the prior art.
The fixing device of the power battery pack of the electric automobile comprises a bottom guard plate, a battery bracket cross beam, a battery bracket longitudinal beam and a fish scale plate which are welded by argon arc welding; the bottom guard plate is connected with the battery bracket cross beam, the battery bracket longitudinal beam and the fish scale plate.
Preferably, the bottom guard plate is welded with the battery bracket cross beam, the battery bracket longitudinal beam and the fish scale plate through argon arc welding.
Preferably, still include battery module and battery management system, battery module and battery management system fix in the die cavity that the fish scale encloses.
Preferably, the integral lift is connected to the body sill beam and the floor cross member.
Preferably, the integral lift is bolted to the body sill beam and floor cross member.
Compared with the prior art, the invention has the following beneficial effects:
1. the mounting structure of the power battery pack of the electric automobile, provided by the invention, has the advantages of simple structure, light weight, high strength, convenience in mounting and firm connection. The invention adopts the aluminum extrusion piece, the extrusion process is mature at home, and no technical risk exists. The invention relates to a light material, which realizes the light weight of a vehicle body. The invention has no independent sealed battery pack, the battery pack is sealed by depending on the bottom plate of the vehicle body, and the battery pack participates in the torsion of the vehicle body, thereby increasing the rigidity of the vehicle body.
