A platform-based design method for the bottom guard plate of new energy vehicles

Abstract

This application relates to a platform-based design method for the bottom guard plate of a new energy vehicle, which belongs to the technical field of chassis protection for new energy vehicles, including: dividing the bottom guard plate into a front bottom guard plate covering the bottom of the vehicle body and a mid-sole guard plate in the same platform model. Plate and rear bottom guard; the length of the front bottom guard is designed based on the model with the shortest front overhang length, and the other models with different front overhang lengths are extended by extending the bottom flange of the front bumper assembly and the front edge of the front bottom guard Lap joint: Design the length of the rear bottom guard plate based on the model with the shortest rear overhang length, and overlap the rear edge of the rear bottom guard plate by extending the bottom flanging of the rear bumper assembly for other models with different rear overhang lengths; The model with the longest wheelbase is used as a reference to design the length of the midsole guard plate, and multiple first die-cut grooves are set on the midsole guard plate to correspond to models with different wheelbase lengths. From the perspective of platform design, this application provides a unique and specific idea to solve the shared solution of the bottom guard plate, which reduces the production cost.

Description

Technical field [0001] This application involves the field of chassis protection technology for new energy vehicles, especially a platform design method for new energy vehicle bottom shields. Background [0002] The bottom guard plate of the car is a protective device attached to the body according to each model, and its functions are: (1) to prevent foreign objects such as water or sediment in the raised road area from splashing into the engine compartment during driving, and to keep the engine compartment clean; (2) Prevent corrosion of the chassis system by rain, ice and snow; (3) Resist the scratching of the chassis system on the abnormally raised ground during driving, as well as the knocking of the exposed engine compartment and oil pipeline due to the crushed gravel hard objects on the road surface due to the wheels; (4) Reduce the resistance of the air flow entering the bottom of the car, reduce the rising force caused by turbulence, and improve the driving stability of t...
