Abstract
A warning device for door lock of car. The door lock has a driving motor to drive a driven shaft to lock the door of the car, and a locking shaft passing through a through hole on the driven shaft. The warning device for door lock of car is characterized in that the through hole is lengthened to form a triggering space and a sensor is provided within the triggering space. When the puller is pulled by external force, the sensor arranged within the triggering space generates a signal to a controlling IC and the controlling IC triggers a driving circuit. The driving circuit drives a loud speaker to alarm the car owner.
