In recent years, intelligent cockpits have become widely popular. In the field of new energy vehicles, the primary and secondary supply units of car companies often use intelligent model pods to demonstrate automotive electronics, such as automotive electric drive, automotive wiring harness, automotive display and other automotive parts. New energy vehicles look not much similar to traditional cars, oil cars, substantially different. So many auto parts companies will make a similar car model, and then install their own parts inside the intelligent model. They place intelligent carrier models at exhibitions, car company research institutes, and their own company exhibition halls to show the company's expertise and the company's new energy vehicle parts, so that the demand for car units can see the feasibility of the physical and performance more intuitively.
