1. A vehicle hinge driving apparatus comprising:
an actuator;
a housing connected to the actuator;
an output shaft rotatably mounted in the housing; and
a transmission mechanism comprising a plurality of gear sets configured to transmit a torque from the actuator to the output shaft, wherein the plurality of gear sets comprises a proximal gear set close to the actuator, a first distal gear set operatively connected to the proximal gear set, and a second distal gear set operatively connected to the first distal gear set;
wherein the second distal gear set is detachably mounted and configured to respond to a required output torque;
wherein the output shaft is connected to the first distal gear set or the second distal gear set;
wherein the housing comprises:
a first mounting end to which the actuator is mounted;
a second mounting end to which the output shaft is mounted;
a first side surface;
a second side surface opposite the first side surface;
a first output-side support recess and a second output-side support recess provided in the second mounting end; and
a cover that is detachably mounted to the second mounting end, the cover comprising a through hole through which the output shaft extends; and
wherein a central vertical axis of the through hole is offset from a central vertical axis of the cover,
wherein the first output-side support recess is adjacent to the first side surface, and the second output-side support recess is adjacent to the second side surface, and
wherein the output shaft is rotatably supported in the first output-side support recess or the second output-side support recess.
