The invention provides an electronic mechanical braking device and system with an embedded lead screw and a vehicle. The electronic mechanical braking device comprises a shell, a braking motor, a speed reducer and a lead screw, the braking motor is used for driving the lead screw through the speed reducer to drive the friction plate, and the shell is used for containing a stator and a rotor of the braking motor, a planetary gear set of the speed reducer and the lead screw; the stator and the planetary gear set are arranged in the axial direction of the brake motor. The planetary gear set is used for transmission connection with the rotor and the lead screw. The stator, the rotor and the lead screw are coaxially arranged, and the lead screw is at least partially embedded in a center hole of the stator or the rotor. According to the electronic mechanical braking device, at least part of the lead screw is embedded into the center hole of the stator or the rotor, the axial size of the electronic mechanical braking device is reduced, and miniaturization is achieved.
