Abstract

An auto anti-theft system with door-mount wireless remote-control pushbutton includes a main controller installed in a car for controlling the operation of the anti-theft system; a remote controller being carried by a user for code matching; and a small-size wireless remote-control pushbutton, which includes a coupling section for mounting the pushbutton to a car of any version or brand on or near a car door, such as on a door handle, a keyhole, a door surface, or a door window. The wireless remote-control pushbutton, the main controller, and the remote controller cooperate with one another to provide the functions of releasing and enabling the anti-theft system directly beside the car without pressing the remote controller button, making the anti-theft system a humanized design.

Claims

1. An automobile anti-theft system, comprising:

a main controller mounted in an automobile for controlling an operation of said automobile anti-theft system;

a remote controller normally carried by a user for code matching with the main controller to unlock a door of the automobile; and

a small-size wireless remote-control pushbutton mounted on or near an automobile door, and configured to activate at least one of said main controller and said remote controller to perform said code matching;

wherein said small-size wireless remote-control pushbutton includes a one-legged coupling section for inserting into a keyhole on a door handle of the automobile.

2. The automobile anti-theft system as claimed in claim 1, wherein said small-size wireless remote-control pushbutton includes a two-legged coupling section for clamping to any of a flat door handle and a door edge.

3. The automobile anti-theft system as claimed in claim 1, wherein adhesive is provided at a back side of said small-size wireless remote-control pushbutton for mounting to an automobile door surface.

4. The automobile anti-theft system as claimed in claim 1, wherein said remote controller carried by the user is set to automatically send a signal at intervals, and said signal sent by said remote controller having a limited effective range;

and said main controller is set to delay when the signal sent by said remote controller is received and checked as correct by said main controller;

the delay time of said main controller being longer than the signal sending interval of said remote controller;

whereby when the user is in a vicinity of the automobile, said wireless remote-control pushbutton must be pushed for said main controller to unlock the automobile door and release the anti-theft system; and

when the user leaves the automobile and closes the automobile door, said main controller may be wakened up to lock the automobile door and enable the anti-theft system simply by pushing said wireless remote-control pushbutton without pressing a remote controller button.

5. The automobile anti-theft system as claimed in claim 1, wherein said main controller is set to be wakened up to send a signal having a limited effective range when the user is in a vicinity of the automobile and pushes said wireless remote-control pushbutton, and said remote controller is set to send a code to said main controller for code matching as soon as said remote controller receives said signal sent by said main controller, and said main controller immediately unlocks the automobile door and releases said anti-theft system when said code sent by said remote controller is checked as correct;

and wherein said main controller is set to be wakened up to lock the automobile door and enable said anti-theft system when the user gets off the automobile, closes the door, and pushes said wireless remote-control pushbutton.

6. The automobile anti-theft system as claimed in claim 1, wherein a master control code is set for said small-size wireless remote-control pushbutton, so that said wireless remote-control pushbutton may control locking and unlocking of all doors of the automobile, and releasing and enabling of said anti-theft system.

7. The automobile anti-theft system as claimed in claim 1, wherein a trunk code is set for said small-size wireless remote-control pushbutton, so that said wireless remote-control pushbutton may control locking and unlocking of a trunk lid, and releasing and enabling of said anti-theft system.

8. An automobile anti-theft system, comprising:

a main controller mounted in an automobile for controlling an operation of said automobile anti-theft system;

a remote controller normally carried by a user for code matching; and

a small-size wireless remote-control pushbutton mounted on or near an automobile door;

wherein said small-size wireless remote-control pushbutton includes a one-legged coupling section for inserting into a keyhole on a door handle of the automobile.

9. An automobile anti-theft system, comprising:

a main controller mounted in an automobile for controlling an operation of said auto anti-theft system;

a remote controller normally carried by a user for code matching; and

a small-size wireless remote-control pushbutton mounted on or near an automobile door;

wherein said remote controller carried by the user is set to automatically send a signal at intervals, and said signal sent by said remote controller having a effective range; and

said main controller is set to delay when the signal sent by said remote controller is received and checked as correct by said main controller;

the delay time of said main controller being longer than the signal sending interval of said remote controller;

whereby when the user is in a vicinity of the automobile, said wireless remote-control pushbutton must be pushed for said main controller to unlock the automobile door and release the anti-theft system; and

when the user leaves the automobile and closes the automobile door, said main controller may be wakened up to lock the automobile door and enable the anti-theft system simply by pushing said wireless remote-control pushbutton without pressing a remote controller button.
