Abstract:
A door locking system for a vehicle including an alarm and comprising:a) a first elongated locking shaft having a transverse through hole; b) a first motor drivingly connected to the elongated locking shaft so as to move the elongated locking shaft in a longitudinal direction; c) a second locking shaft, the second locking shaft being movable so as to extend into the through hole of the first, elongated, locking shaft, a height dimension of the second locking shaft being less than a corresponding dimension of the through hole such that, when the second locking shaft extends into the through hole, a triggering space is formed between the second locking shaft and a side of the through hole; d) a second motor drivingly connected to the second locking shaft so as to move the second locking shaft; e) an alarm system including a control integrated circuit (IC) connected to a driving circuit which is, in turn, connected to a speaker; and, f) a sensor located in the triggering space and connected to the control IC whereby, when the second locking shaft is engaged with the through hole, movement of the first locking shaft relative to the second locking shaft, indicative of an unauthorized attempt to unlock the vehicle, causes the sensor to generate a signal to the control IC and activate the alarm system.
