Abstract

An anti-theft device with a trigger applied in a portable electronic device is provided, which has a trigger electrically connected with a trigger unit selectively. When the trigger is separated from the trigger unit, a sensing element begins to carry out the sensing operation, and the portable electronic device is put into a power saving mode. When the sensing element senses that the electronic device has been moved, it transmits a signal to a processor. Meanwhile, the portable electronic device and an alarm unit of the trigger will be enabled simultaneously, making a sound to warn the user.

Claims

1. An anti-theft device with a trigger, applied in a portable electronic device, comprising:

a processor, for receiving and transmitting signals;

a sensing element, electrically connected with the processor;

a trigger unit, electrically connected with the sensing element; and

a trigger, electrically connected with the trigger unit selectively;

wherein when the trigger is separated from the trigger unit, the sensing element is enabled;

when the trigger is coupled with the trigger unit, the sensing element is disabled.

2. The anti-theft device with a trigger according to claim 1, wherein the sensing element is a shock sensor.

3. The anti-theft device with a trigger according to claim 1, wherein the sensing element is a level sensor.

4. The anti-theft device with a trigger according to claim 1, wherein the trigger has an alarm unit, and when the sensing element transmits a signal to the processor, the trigger will be enabled to make an alarm by a wireless transmission module.

5. The anti-theft device with a trigger according to claim 4, wherein the trigger is a remote controller.

6. An anti-theft device with a trigger, applied in a portable electronic device, comprising:

a processor, for receiving and transmitting signals;

a sensing element, electrically connected with the processor;

a trigger unit, electrically connected with the sensing element and the processor; and

a trigger, electrically connected with the trigger unit selectively, wherein when the trigger is separated from the trigger unit, the sensing element is enabled, and the signal is transmitted to the processor by the trigger unit, so that the portable electronic device enters into a power saving mode;

when the trigger is coupled with the trigger unit, the sensing element is disabled, and the portable electronic device is woken up from the power saving mode.

7. The anti-theft device with a trigger according to claim 6, wherein the sensing element is a shock sensor.

8. The anti-theft device with a trigger according to claim 6, wherein the sensing element is a level sensor.

9. The anti-theft device with a trigger according to claim 6, wherein the trigger has an alarm unit, and when the sensing element transmits a signal to the processor, the trigger will be enabled to make an alarm by a wireless transmission module.

10. The anti-theft device with a trigger according to claim 9, wherein the trigger is a remote controller.
