1. A vehicle door lock assembly, including:
a housing;
a first locking assembly, disposed on the housing, including an inner handle, an outer handle and a first lock tongue, the first lock tongue having a tendency to move outward of the housing, the inner handle and the outer handle being movably disposed on the housing and respectively controlling the first lock tongue to move inward of the housing;
a second locking assembly, disposed on the housing, including a second lock and a second lock tongue, the second lock tongue including a first segment and a second segment slidably connected with each other, the first segment and the second segment having a first elastic member disposed therebetween so that the first segment and the second segment have a tendency to move away from each other, the second lock including a mandrel and a connecting rod, the mandrel having an assembling portion, the connecting rod connected between the first segment and the assembling portion;
a driving module, including a motor assembled with the mandrel, the second lock tongue being slid and the second segment moved inward or outward of the housing when the motor drives the mandrel to rotate forward or reversely; and
a micro switch, including an inductive element, the assembling portion having an inductive portion radially protruding therefrom; wherein when the motor drives the mandrel to rotate forward or reversely, the inductive element is inducted with the inductive portion and the micro switch stops a movement of the motor;
wherein the second locking assembly further includes a control member, the control member is assembled with the mandrel and located out of the housing, the driving module further includes a first gear and a second gear, the first gear is disposed on the motor, the second gear is sleeved to the mandrel and assembled with the first gear, the mandrel further has a second elastic member, and the second elastic member is elastically abutted against the second gear so that the second gear has a tendency to abut against a flange radially extending from the mandrel to generate a frictional force.
