The invention relates to a vehicle-mounted navigation system for a new energy automobile based on an Internet of Things. The vehicle-mounted navigation system for the new energy automobile based on the Internet of Things comprises a main body and a display screen and further comprises a light shielding mechanism and a charging mechanism; the light shielding mechanism comprises a lifting assembly and a turnover mechanism; and the charging mechanism comprises a moving assembly and a charging assembly. According to the vehicle-mounted navigation system for the new energy automobile based on the Internet of Things, by using the light shielding mechanism, lights irradiated to the display screen are shielded to avoid light reflection of the display screen so that a visible effect is enhanced andnavigation information is convenient for drivers to watch; a solar cell panel can also be utilized to generate power to save energy; and moreover, the display screen can be covered to achieve a protecting effect; and by using the charging mechanism, the moving of a USB interface can be controlled to enlarge the charging range to be convenient for primary drivers or secondary drivers to charge a mobile phone; and therefore, the practicability of the vehicle-mounted navigation system for the new energy automobile is enhanced.
