AUTOMOBILE ANTI-THEFT SYSTEM

摘要

A remote-controllable automobile anti-theft device (20) which replaces a common connection between the accelerator (26) and the throttle (38) of an automobile with a locking main shaft connector (45) between an accelerator shaft (22) and a throttle shaft (28). The locking main shaft (45) rotates about a central axis in response to motion from the accelerator (26), and translates that motion to the throttle (38). The locking main shaft (45) contains a hole (51). The remote control activates a push-pull solenoid (30) which reversibly inserts a solenoid locking pin (31) into the hole (51) in the locking main shaft (45). When the solenoid locking pin (31) is inserted into the hole (51) in the locking main shaft (45), the locking main shaft (45) is prevented from rotating around its pivot axis. Therefore, when the locking pin (31) is inserted into the hole (51) in the locking main shaft (45), motion of an accelerator shaft (22) does not translate to the throttle shaft (28), and the automobile's engine cannot rev. In addition, the invention has tamper-resistant features such as being attached to the fire wall (24) of the automobile by tamper resistant fasteners (25) which are inserted from the engine side of the fire wall. Therefore, to remove the fasteners, the person removing the fasteners must have access to the engine side of the fire wall. In addition, the accelerator shaft (22) contains a spring mechanism so that the accelerator pedal (26) can still be pushed to the floor even when the device is locked.
