The invention discloses an electric steering column worm and gear mechanism, an electric steering system and a vehicle. The electric steering column worm and gear mechanism comprises a shell; a worm and gear, wherein the worm and the gear are arranged in the shell, the worm wheel and the worm are connected in a meshed mode, and the two ends of the worm are connected with the shell through a first bearing and a second bearing respectively; a motor, wherein the motor shaft is rotatably arranged in the shell, the motor shaft is provided with a coupler assembly, the coupler assembly is connected with the end, penetrating through the first bearing, of the worm, and the motor shaft and the worm are eccentrically arranged and are adjacent to the gear; and an elastic piece, wherein the elastic piece is connected with the shell, the second bearing is installed on the elastic piece, and the elastic piece is constructed to be suitable for providing acting force towards the gear for the second bearing. According to the worm and gear mechanism of the electric steering column, a new vehicle and a durable steering system are good in rattle noise evaluation performance on a bumpy road, and the worm and gear mechanism is simple in design and easy to control.
