Pneumatic inducing safety device of vehicle

Abstract

An air pressure induction type antitheft device for car features use of an air pressure detector for the internal air in a car. When it is detected that the instantaneous variation of air pressure in the car is greater than a predefined pressure value, a pressure exception signal is outputted to control the alarm device for generating alarm signals.

Description

Technical field [0001] The invention relates to an automobile anti-theft device, in particular to an air pressure induction type automobile anti-theft device. Background technique [0002] It is known that car owners usually install car anti-theft devices in order to avoid the theft of their cars or accidents. When the car owners are not in the car, they can activate the anti-theft devices and use various detectors to detect abnormal conditions. [0003] Therefore, if the vehicle is abnormal, for example, when the vehicle is invaded, the detector will detect and trigger the car anti-theft device. Traditional car anti-theft devices are mostly noticed by the piercing chirping sound, which can make thieves escape and fail to succeed when they hear the sound. situation. [0004] However, although the tweet function of the traditional car anti-theft device can effectively deter theft, the range of the tweet sound is limited. The owner may not be able to hear the tweet sound of the ant...

AI Technical Summary

Problems solved by technology

Most of the traditional car anti-theft devices are eye-catching by the harsh chirping sound, which can make the thief escape and fail to succeed, or let the car owner rush back to the vehicle parking place to care about the abnormality after hearing the chirping sound of the anti-theft device. situation

[0004] However, although the beeping function of the traditional car anti-theft device can effectively deter theft, the range of the beeping sound is limited. The car owner may not be able to hear the beeping sound from the anti-theft device, and often misses the opportunity for rescue.

In addition, or when the car is towed, even if the anti-theft device keeps beeping along the road, it is not easy for the car owner in the distance to be aware of the abnormal condition of the car, or even unable to track it. Only when the car owner returns to the parking place will he find out The car has been towed away

Many of the above situations are due to the fact that the known anti-theft device does not have the function of proactively notifying the car owner, not only cannot completely guarantee the safety of the vehicle, notify the car owner in real time, but also cause noise problems to the surroundings, which is not very ideal
