Description

Automobile anti-theft and engine anti-water-soaking protector
Technical Field
The invention relates to a protection device for improving functions of an automobile anti-theft system and preventing water from being soaked in an engine, in particular to an automobile anti-theft and engine water-soaking prevention protector.
Background
In recent years, with the rapid increase of the quantity of domestic automobiles, particularly household cars, convenience is brought to people for going out, and the quality of life and the happiness index are continuously improved. But at the same time, the incidents that add annoyance and economic loss to the vast owners of automobiles also occur everywhere. On the one hand, automobile theft incidents are increasing year by year. According to related aspects, 10 thousands of automobile theft cases occur every year in China, and 300 automobiles are stolen on average every day. On the other hand, countless vehicles are invaded by water every year due to urban inland inundation caused by extreme weather such as heavy rain, typhoon and the like, so that the vehicles become soaked in water, light people consume large repair cost, heavy people scrap engines, and the property of people is seriously lost.
The automobile anti-theft technology is always a popular research in the field of automobiles at home and abroad, the anti-theft technology is also developed from simple mechanical and electronic type to the remote key chip type anti-theft system which is widely applied at present, and is developed from a single steering column lock to technologies of unlocking and cutting off a circuit and an oil way without a key, simultaneously giving an alarm and the like, on the premise of ensuring the safety of the key, the automobile is relatively safe, but if an illegal person obtains the automobile key by means of cheating, robbery and the like, the automobile can still be robbed and stolen. At present, no related product is applied in the aspect of preventing water invasion of an automobile engine.
Disclosure of Invention
In order to further improve and enhance the anti-theft function of the automobile and prevent water from invading the scrapping loss of the automobile engine, the invention provides a protection device which can not start the automobile even if a key of the automobile is held by hands under the condition that a non-owner or others obtain the authorization of the owner and has the function of preventing the automobile engine from soaking water.
The invention mainly comprises a shell, a rotary valve mechanism, a transmission system and an electric control system, wherein the installation positions are respectively arranged behind an air filter of an automobile air inlet system and in front of a rear silencer at the tail end of an exhaust system, and the main function of the invention is that after the automobile is parked, when the set exhaust gas exhaust time limit of the automobile exhaust system is finished, an air inlet pipe and an exhaust pipe of an automobile engine are automatically closed, and an air inlet channel and an exhaust channel of the engine are cut off. When the vehicle runs again, the owner or an authorized person of the owner firstly starts the automobile engine air inlet and exhaust pipe by means of fingerprints or passwords, then the automobile can be started by one key or the key is used for starting the automobile, and otherwise, the automobile cannot be started even if the key is held by hands. Therefore, the invention not only can effectively prevent the engine damage accident caused by the water soaking of the automobile, but also can effectively improve and enhance the anti-theft function of the automobile, thereby ensuring that the property of people is not lost.
The invention has the advantages that the invention can achieve the purposes of avoiding the damage and the scrapping of the engine of the automobile caused by water invasion, greatly reducing the maintenance cost of the vehicle with water soaking and improving and enhancing the anti-theft function of the automobile on the premise of not changing the pipe diameter of an air inlet system and an air outlet system of the automobile and not changing the original structure of the automobile.
