Abstract

The invention discloses a method for producing a pure-electric car battery box assembly. The battery box assembly is divided into a battery box upper cover assembly and a battery box tray assembly, and after a battery is assembled, the battery box upper cover assembly is buckled onto the battery box tray assembly; the battery box upper cover assembly is produced by adopting SMC (sheet mounting compound) in the steps such as pressing, perforating and assembling; the battery box tray assembly is produced by adopting SMC in the steps such as pressing, perforating, bonding of iron members outside the battery box tray, bonding of iron members inside the battery box tray and assembling. The pure-electric car battery box assembly produced through the method has excellent aging resistance, excellent corrosion resistance, excellent flame retardant property and low smoke generation density, the good strength can be maintained in a wide temperature range, and the good solvent resistance can be maintained in a severe environment. The weight is low, and the light-weight tendency of a car can be satisfied.

Description

technical field [0001] The invention relates to the technical field of manufacturing electric vehicle accessories, in particular to a method for manufacturing a pure electric vehicle battery box assembly. Background technique [0002] Vehicle lightweight has always been an important research content of automotive technology. The advantages of pure electric vehicles are: 1) no pollution and low noise; 2) simple structure, convenient use and maintenance; 3) high energy conversion efficiency; at the same time, the energy during braking and downhill can be recovered to improve energy utilization efficiency; 4 ) can use the cheap "valley power" of the power grid to charge at night, and play a role in smoothing the peak-valley difference of the power grid. [0003] However, due to the arrangement of battery packs in pure electric vehicles, the weight of the whole vehicle increases a lot, and the problem of lightweight is more prominent. The design of the battery box of an electr...
