Description
Technical Field
The application relates to the technical field, in particular to an electric automobile diversion cover plate and a diversion structure.
Background
The water management performance of the whole vehicle refers to the comprehensive performance of the adaptability of the vehicle in water, salt water and muddy water, the water sealing performance of the vehicle and the drainage capability after water intrusion, and is a performance development mode for uniformly developing and uniformly managing the water properties of the whole vehicle in the forward development of the performance of the whole vehicle. In short, the development mode of the adaptation performance of the vehicle to water is adopted.
With the continuous delivery of multiple national standards, related requirements such as waterproof of the whole vehicle are further enhanced to improve the safety of the vehicle, and the water management performance of the vehicle, which is one of the most perceived performance of users, is increasingly and more valued by vehicle enterprises, so that the vehicle water management performance is one of key performance indexes in the development of the whole vehicle. In order to avoid serious perceived quality problems such as water management and the like of automobiles under the working conditions such as rain, car washing, wading, rain and fog and the like, the development capability of the water management of the automobiles needs to be improved through early design control, and the technical difficulties related to the water management are overcome. In the manufacturing process, the production process is controlled, the quality of parts or systems is improved, and the market vehicles are ensured to have no corresponding water management quality problem through reasonable and scientific product development.
In the prior art, interaction of a vehicle with water and dust is analyzed through CFD simulation, behavior of the vehicle in a severe environment is predicted, and driving safety and vehicle reliability are improved. The simulation of CFD (Computational Fluid Dynamics ) in whole vehicle water management mainly comprises whole vehicle wading, A column overflow, rain analysis and vehicle body pollution.
The whole vehicle wading analysis mainly researches whether the risks of water inlet of an engine, electric short circuit, firewall water seepage and the like exist after the vehicle drives through a water pit with a certain depth at a certain speed. With the development of electrification of automobiles, more and more electric elements including battery packs and the like are arranged on an automobile chassis, and if a short circuit problem occurs in the wading process of the whole automobile, the running of the automobile is affected, and the safety of drivers and passengers is possibly endangered.
The A column overflow mainly researches the influence of rainwater on the visual field of the side window caused by the overflow of the A column to the side window after the front windshield forms a liquid film. The rain analysis and analysis mainly focuses on whether the drainage capacity of a drainage tank is enough after the automobile is in rain, whether the risk of submerging an air conditioner air inlet or sucking rainwater into the air conditioner air inlet exists, and whether sensitive electric devices such as a wiper motor and the like have soaking risks. Vehicle body pollution is mainly concerned with accumulation of dust on the surface of a vehicle body caused by wheel splash, rear window pollution caused by wake vortexes of an automobile, and the like. Because water management involves multiphase flow and transient analysis, conventional CFD software is typically very slow to calculate when analyzing. One round of whole vehicle wading analysis with starccm+ is calculated on HPC (High Performance Computing, high performance computer cluster) and may take one to two weeks. The Powerflow and SPH (Smoothed Particle Hydrodynamics, smooth particle fluid dynamics) method Preonlab using LBM (Lattice Boltzmann Method, lattice boltzmann) method has great advantage in terms of calculation time, and can shorten the simulation time to about one day.
In the actual development process, the simulation application of the whole vehicle water management is also participated in specific projects to a certain extent, for example, A column overflow analysis can be carried out in the early stage of modeling, and requirements are put forward on modeling development. After the whole vehicle data is released, the whole vehicle wading analysis can be carried out, the wading risk is checked, and some requirements are put forward on the whole vehicle arrangement. Rain analysis can also provide some guidance for the placement of the water guide.
