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 auto anti-theft system with door-mount wireless remote-control pushbutton, comprising:

a main controller mounted in a car for controlling the 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 a car door.

2. The auto anti-theft system with door-mount wireless remote-control pushbutton as claimed in claim 1, 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 car.

3. The auto anti-theft system with door-mount wireless remote-control pushbutton 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.

4. The auto anti-theft system with door-mount wireless remote-control pushbutton as claimed in claim 1, wherein said small-size wireless remote-control pushbutton is provided at a back side with adhesive for mounting to a car door surface.

5. The auto anti-theft system with door-mount wireless remote-control pushbutton as claimed in claim 1, wherein said remote controller carried by the user is set to automatically send a signal at intervals of a few seconds, and said signal sent by said remote controller having an effective range of a few meters;

and said main controller is set to hold on for a few seconds when the signal sent by said remote controller is received and checked as correct by said main controller;

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

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

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

6. The auto anti-theft system with door-mount wireless remote-control pushbutton as claimed in claim 1, wherein said main controller is set to be wakened up to send a signal having an effective range of a few meters when the user is in the vicinity of the car 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 a signal sent by said main controller, and said main controller immediately unlocks the car 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 car door and enable said anti-theft system when the user gets off the car, closes the door, and pushes said wireless remote-control pushbutton.

7. The auto anti-theft system with door-mount wireless remote-control pushbutton 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 the locking and unlocking of all doors of the car, and the releasing and enabling of said anti-theft system.

8. The auto anti-theft system with door-mount wireless remote-control pushbutton 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 the locking and unlocking of a trunk lid, and the releasing and enabling of said anti-theft system.
