The invention relates to a novel electric folding multifunctional seat central armrest which comprises a large backrest framework installed on a back row seat and an electric central armrest rotationally connected to the large backrest framework, and the electric central armrest comprises a spline shaft, a metal support, an armrest framework, a rotating shaft protective sleeve, a gear rotating disc, a gasket, a locking screw and a motor. Spline holes allowing the spline shaft to penetrate through are coaxially formed in the tail ends of the metal support and the armrest framework, a via hole allowing the spline shaft to penetrate through is formed in the large backrest framework, and the armrest framework is rotationally connected into a rotating shaft protective sleeve arranged on the large backrest framework through the spline shaft. The key shaft penetrates through a rotating shaft sheath of the backrest large framework and is connected with a spline hole of a gear turntable arranged on the outer side of the backrest large framework, and a gear on a driving shaft extending out of the motor is meshed with teeth on the outer circumference of the gear turntable. The electric armrest has the advantages that the electric armrest is more labor-saving to operate, the comfort of passengers in the back row is greatly improved, and the electric armrest is simple in structure and can be universally applied to other seat armrests in the market.
