Beschreibung
Zusammenfassung:	Provided is an electric cable driving mechanism having a self-return function. The electric cable driving mechanism includes a housing assembly, an electric motor, a three-stage transmission mechanism and a multifunctional nut, where the three-stage transmission mechanism includes a coil spring assembly, the electric motor is fixed to the housing assembly, and the three-stage transmission mechanism and the multifunctional nut are mounted in the housing assembly; and the multifunctional nut includes two cable mounting grooves and is in transmission connection to the electric motor by means of the three-stage transmission mechanism. According to the electric cable driving mechanism having a self-return function of the present disclosure, the three-stage transmission mechanism is used, and outputs a larger force compared with two-stage transmission; and a split multifunctional screw rod is easy to mount, such that mounting of a coil spring during assembly is prevented from scratching the screw rod, and the problem of abnormal noise generated during mounting of the coil spring is solved.
