Description

Automobile auxiliary device and method for pulling out automobile key only when passenger in automobile is safe

Technical Field

An automobile auxiliary device and a method for pulling out an automobile key only when a passenger in an automobile is safe belong to the technical field of automobile design, and particularly relate to an automobile auxiliary device and a method for pulling out an automobile key only when the passenger in the automobile is safe.

Background

The mechanical automobile ignition lock (or automobile ignition switch) is installed on the lock mechanism of the automobile steering column, is a main switch for opening or closing the automobile ignition coil circuit, and comprises a lock core, an ignition rotor and other structures. The lock cylinder is used for inserting a vehicle key, and the ignition rotor switches on contacts arranged in each gear circuit through contact conduction structures (contact pieces and contact discs) arranged on the ignition rotor, so that each function is realized.

The existing automobile ignition LOCK generally has four gears of LOCK, ACC, ON and START: LOCK gear: the locking gear is a key inserting and pulling position, the circuit is completely closed except the anti-theft system and the small lamp in the vehicle at the moment, and the steering wheel is locked; ACC gear: when the key is screwed to the position, the accessory circuit is connected, and equipment such as a radio can be used; ON gear: when the key is screwed to the position, the whole vehicle circuit is switched on, the system can perform necessary preparation work and self-checking work for starting the engine, the key can be kept at the position when the vehicle normally runs, and all circuits of the whole vehicle are in a working state; START gear: and a starting gear, when the key is screwed to the position, the circuit of the starter is switched ON, the engine can be driven to operate and start, and the key can automatically return to the ON gear after being loosened.

Some drivers lock the passengers in the vehicle intentionally (for example, the drivers think that the drivers will come back soon and lock the children in the vehicle temporarily) or unintentionally (for example, forget that the passengers are in the vehicle), and at least dozens of events that the children are forgotten in the vehicle have occurred according to incomplete statistics. Particularly, passengers (especially children) are locked in the vehicle reversely in summer, and due to high temperature and oxygen deficiency in the vehicle, the heat shooting disease and the oxygen deficiency suffocation are caused after a long time, so that the life safety hidden danger is caused.

And occasionally, the situation that the driver does not lock the whole vehicle door to let others enter the unlocked vehicle and then the others are locked in the sealed vehicle reversely can cause life safety hazards.

As the automobile is known to be one of the precious wealth of people, basically people can treasure the precious wealth, so that a driver can close a window, lock a door and take away keys after getting off the automobile, and the behaviors are common knowledge behaviors.

The invention is developed based on the common knowledge behaviors that a driver closes a vehicle window, locks a vehicle door, takes away a vehicle key and the like after getting off and the related characteristics of the automobile ignition lock.

The basic principle of the invention is as follows: firstly, the car key becomes the last person or object leaving the car (namely, under the general condition, the passenger is required to pull out the car key after getting off the car); secondly, if the passenger does not need to get off the vehicle under special conditions, the driver can take away the vehicle key after the passenger who does not need to get off the vehicle stays in the safe vehicle space by adopting safety measures such as opening a non-driver seat window and/or opening a non-driver seat door and/or unlocking a non-driver seat door lock, and the like, so that the safety of the passenger is also ensured; thirdly, after the driving passengers get off the vehicle, the processor unit can automatically close all windows and close and lock all doors to prevent other people from entering the vehicle without locked windows and doors on the premise of determining that no passenger exists in the vehicle.
