Automobile anti-theft device

Abstract

Disclosed is an automobile anti-theft device. The automobile anti-theft device comprises a processor, a current control unit, a first Bluetooth transmitter and a manipulator. The processor, the current control unit and a signal transmitter are arranged on a starting battery of an automobile. The processor is electrically connected with the current control unit, the first Bluetooth transmitter, an electric generator of the automobile and an electricity storing unit of the starting battery. The processor is used for controlling the current control unit to run. The current control unit is used for controlling the starting battery to output currents to circuitry of the automobile. The current control unit comprises a large current circuit and a small current circuit which are connected in parallel. The large current circuit is provided with a single-pole relay. The small current circuit is a current limiting circuit and provided with a self-recovering type fuse and a small current breaker. The processor controls the single-pole relay and the small current breaker to be started and stopped for operation. The manipulator comprises a second Bluetooth transmitter. The processor and the manipulator are in wireless connection through the first Bluetooth transmitter and the second Bluetooth transmitter.

Description

technical field [0001] The present invention is related to the anti-theft of automobiles, and furthermore, it refers to an anti-theft device for automobiles. In the anti-theft mode, the anti-theft device for automobiles can only control the starting battery to output a small current to supply electronic devices such as driving computers and car stereos. Due to the power demand, it is impossible to output a large current to supply the starter motor of the car, so as to prevent the car from being stolen. Background technique [0002] China Taiwan patent TWM416829 discloses a kind of anti-theft lithium power battery, including a control device installed on the lithium power battery of the vehicle, a remote controller outside the vehicle, and a voice announcer inside the vehicle, wherein the remote controller is used for Control the control device. [0003] The control device is composed of a circuit board, a battery management system on the circuit board, a security system on ...

Problems solved by technology

[0006] However, the TWM416829 patent did not create an explanation, recording the technical means of how to prevent the vehicle from starting when the current limiting circuit is activated, and the starting battery of the vehicle is electrically connected to the circuit system of the vehicle through the current output terminal of the battery. The vehicle supplies electric energy. The current-limiting circuit of TWM416829 can maintain the function and output a small current in the anti-theft mode to supply the electronic equipment of the vehicle. It means that the battery and the circuit system of the vehicle are in a state where current can pass, and the battery can also pass through the same current path. Outputting a large current to the vehicle cannot achieve the effect of making the vehicle unable to start as described in the abstract

[0007] Furthermore, the existing car anti-theft devices including TWM416829 implement the remote control or chip key to open or release the anti-theft mode. When the remote control or chip key is copied by Xiaoxiao, Xiaoxiao can hold the copied key The remote control or chip key cancels the anti-theft setting, and then the vehicle can be easily driven away. Therefore, when the remote control or chip key is in danger of being copied, the car owner must go to the manufacturer to install the anti-theft device installed on the vehicle together with the remote control or chip key. to replace
