Abstract
The invention provides a light-weight structure for a battery box of an electric vehicle, which includes an upper cover plate assembly (110), a 3D printing lightweight box assembly (120), a bottom bracket assembly (130), and a hoisting column (140); wherein, the upper cover plate assembly (110) is located above the 3D printing lightweight box assembly (120), and is fastened and installed with structural glue and bolts; the bottom bracket assembly (130) is located on the 3D printing lightweight The bottom of the quantitative box assembly (120) is fitted with structural glue; the battery pack is placed in the space left by the battery box assembly (100); the hoisting column (140) passes through the 3D printed lightweight box The body assembly (120), the upper cover plate assembly (110), and the bottom end bracket assembly (130) reserve holes, and are hoisted on the bottom of the vehicle body through the hoisting column (140) as an installation point. The weight of the battery pack in the present invention is reduced, and the ABS shell is used instead of the steel shell, so that the overall quality of the battery pack is reduced on the premise of ensuring various performances.
Description
technical field [0001] The invention relates to the field of lightweight design of battery pack boxes for electric vehicles, in particular to a lightweight structure and design method for the battery pack boxes of electric vehicles. Background technique [0002] At present, the new energy automobile industry represented by electric vehicles is booming in China, and battery packs are the core components of electric vehicles. At present, in order to improve the battery life of pure electric vehicles, it is necessary to increase the electrical performance parameters such as the output power of the battery, which often leads to the use of a large number of battery modules and large volumes, resulting in an increase in vehicle quality, which is not conducive to its battery life. promote. Based on this, there is an urgent need to reduce the weight of the housing carrying the battery module series on a large scale to meet the lightweight requirements of the entire battery pack ass...
