The invention provides a rotating mechanism used for a display terminal and a vehicle with the rotating mechanism. The rotating mechanism used for the display terminal comprises a mounting unit and adriving unit, wherein the mounting unit is used for installing the display terminal, the driving unit comprises a power source and a speed reducer, the speed reducer is provided with a power output piece capable of outputting torque, the power output part is in power coupling connection with the mounting unit, and the speed reducer at least comprises a planetary gear transmission mechanism. According to the rotating mechanism, not only the display terminal can be rotated to a proper angle according to the requirements of a user so as to improve the use experience, but also rotation of the display terminal is more stable and powerful after the display terminal is subjected speed reduction and torque increasing by the speed reducer, and noise and shaking of the display terminal during rotation can be effectively reduced.
