Motor vehicle anti-theft alarm

Abstract

The invention discloses a motor vehicle anti-theft alarm which can send an alarming signal when a thief attempts to steal and touches a motor vehicle. The motor vehicle anti-theft alarm is characterized in that the motor vehicle anti-theft alarm comprises a vehicle tracing positioning device and a relay controlling a battery to supply power to the motor vehicle, the vehicle tracing positioning device is internally provided with a sound-control circuit and sends the alarming signal to a mobile phone of a vehicle owner through a satellite according to the sound-control circuit, and the vehicle tracing positioning device is mounted in a sealed shell; and the interior of the sealing shell and air in the outside world are isolated, and at least one bead is further placed into the sealing shell.According to the motor vehicle anti-theft alarm, mistaken alarming can be prevented from being generated under the influence of sound from the outside world, and the accuracy of signal alarming is improved.

Description

technical field [0001] The invention belongs to an anti-theft alarm device for a motor vehicle, and relates to a structure modification of an anti-theft device that can send a motor vehicle position signal to a mobile phone at any time by using a tracking locator or send a flameout control signal to the motor vehicle from the mobile phone, more specifically, The utility model relates to a motor vehicle anti-theft alarm device which can send out an alarm signal when a thief tries to steal and touches the motor vehicle. Background technique [0002] Most of the motor vehicle anti-theft alarms have adopted a tracking locator, which can send the signal of the vehicle position to the owner's mobile phone through satellites at any time. When the owner finds that the vehicle is stolen, the mobile phone can control the tracking locator through the satellite, so that The tracking locator prevents the motor vehicle from starting or shutting down the motor vehicle. At the same time, th...

[0003] However, there are many reasons for external vibrations, such as thunder, sirens and firecrackers, etc., which can cause the tracking locator to send out wrong alarm signals, making people tired of precautions and neglecting to take care of them. It may be possible to prevent a strong sound from the device or change the circuit, so that the sound control circuit will not provide an alarm signal to the tracking locator, so the tracking locator may be cut and discarded. The tracking locator prevents the motor vehicle from starting or shutting down the motor vehicle, and the vehicle's location signal in the mobile phone cannot accurately reflect the actual location of the motor vehicle

[0004] In the existing structure, the control system of the motor vehicle circuit is realized by the pull-in or release of the relay. Usually, the method of connecting the circuit with a normally closed connection is used for connection. The relay must be connected in the circuit where the battery supplies power to the motor vehicle, and the tracking locator is often connected by a wire and separated from the relay in space so that it can be hidden in a hidden place, thereby increasing the time for the thief to find the tracking locator. However, In the case that the car owner cannot receive or receive the alarm signal early, it becomes almost meaningless to increase the time for the thief to find
