Electronically controlled actuating mechanism

The electronically controlled actuating mechanism comprises a motor, a first driving gear connected with the motor, a first duplicate gear and a planetary gear mechanism, and the planetary gear mechanism comprises a second duplicate gear, an inner gear ring, a planetary gear and an output shaft assembly. The first duplicate gear comprises a first driven gear meshed with the first driving gear and a second driving gear, the second duplicate gear comprises a second driven gear meshed with the second driving gear and a sun gear, and the second driven gear is provided with a first containing groove containing the inner gear ring. The electronically controlled actuating mechanism is compact in overall structure and reasonable in space utilization, the overall size and weight can be reduced, and the cost of materials and parts is reduced. 本发明公开了一种被电子控制的执行机构，包括电机、与电机连接的第一主动齿轮、第一双联齿轮和行星齿轮机构，行星齿轮机构包括第二双联齿轮、内齿圈、行星轮和输出轴总成，第一双联齿轮包括与第一主动齿轮相啮合的第一从动齿轮和第二主动齿轮，第二双联齿轮包括与第二主动齿轮相啮合的第二从动齿轮和太阳轮，所述第二从动齿轮具有容纳所述内齿圈的第一容置槽。本发明的一种被电子控制的
