1. A single motor-driven double push rod electric vehicle tailgate system, comprising:
a beam assembly, configured for being fixed on an automobile;
a follow-up plate;
a lifting arm; and
a lifting power assembly comprising a first lifting push rod, a second lifting push rod, a motor, and a transmission mechanism coupled to the motor;
wherein a top end of the follow-up plate is hinged to the beam assembly, a middle of the follow-up plate is hinged to a lower end of the lifting arm, and a bottom end of the follow-up plate is hinged to a bottom end of either the first lifting push rod and the second lifting push rod;
a retractable end of the first lifting push rod or the second lifting push rod is hinged to the middle-lower end of the lifting arm;
the transmission mechanism comprises at least one connecting shaft rotatably coupled to the motor, enabling the first lifting push rod and the second lifting push rod retractable along a certain direction thereby driving the lifting arm moving to open or close the tailgate.
