The invention relates to an optimum design method of the internal structure of an opening/closing mechanism of an automobile electric back door. The optimum design method comprises the following steps: internal friction of the mechanism is adjusted through the adjustment of a friction gap s of an inner cylinder and an outer cylinder, in the sliding fit, of the opening/closing mechanism of the automobile electric back door; the internal gap s of the opening/closing mechanism of the electric back door is verified and optimized through experimental verification and test data processing, so that when the opening/closing mechanism of the electric back door performs electric operation, the service efficiency Eta of a motor assembly is equal to or smaller than the safety efficiency Eta0 of a motor, and the manual operation force Fh is equal to or smaller than 100N; therefore, the service efficiency of the motor assembly is the highest, the service life of the motor is long, and the manual operation force is reasonable.
