Description

A kind of safe anti-theft car key

technical field

The utility model relates to a car key using electronic technology and wireless communication technology, in particular to a safe anti-theft car key.

Background technique

At present, there are many cases in the society when car owners park in public places, and the car windows, doors and trunk are all intact, and the property in the car is stolen. The reason for the analysis is that criminals use signal jammers in public parking lots. When the owner parks the vehicle and gets off the car, he closes the door and presses the remote control car key lock button to lock the car. Due to the presence of signal jammers near the vehicle , the vehicle failed to receive the corresponding lock signal, resulting in the door not being locked successfully. Therefore, the car owner left the parking lot without knowing that the vehicle was not successfully locked, resulting in the theft of the property in the car.

Currently on the market, there are many car anti-theft devices and products that can remotely alarm and notify the owner after the door is illegally opened, or install a GPS device on the vehicle to accurately locate the stolen vehicle. This device all can't solve the above-mentioned occurring problem.

Chinese patent 2014205812665 discloses a car key whose main features include a vibration sensor, a microprocessor and a signal transmitter; the microprocessor is electrically connected to the vibration sensor and the signal transmitter respectively; the signal transmitter is electrically connected to the vehicle communication; the vibration sensor The vibration signal is detected in real time, and the vibration signal is sent to the microprocessor, and the microprocessor controls the signal transmitting device to send a signal to the car according to the received vibration signal. The main function of this patent is that the design is reasonable, the structure is simple, the car-finding function can be realized automatically and the energy is saved.

Chinese patent 2015201513739 discloses a car key. Its main feature is that the key body is provided with one or more control buttons, a button detector electrically connected to the control button and a prompter controlled by the button detector, and the button detector triggers the button detector when the control button is triggered. The prompter sends out prompt information. This patent mainly solves the technical problem that the user cannot know whether the corresponding control button is effectively triggered after clicking the control button.

The above two patents and the products on the market, to a certain extent, allow car owners to obtain more information about the vehicle in real time, and communicate with the vehicle through the car key, but both fail to solve the problems mentioned above.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, to provide a safe and anti-theft car key, to give a clear indication status to the various operations done by the owner, and to remind and warn the unsuccessful operations in time, to help The owner of the vehicle discovers a potential safety hazard in the vehicle.

The using method of the utility model is:

When the lock button is pressed, the lock command is transmitted to the control unit, and then the lock command is sent through the wireless communication module. At the same time, the control unit will continue to light up for two seconds and transmit the command to the door unlocked indicator light/battery status indicator The light keeps it on for two seconds. If the wireless communication module receives the locked car command returned by the car control system within two seconds, the locked car command is transmitted to the control unit, and the control unit transmits the off command to the door unlocked indication. If the wireless communication module does not receive the locked car command returned by the car control system within two seconds, and no locked car command is transmitted to the control unit, the control unit will continue to flash the command to the The door unlocked indicator/battery status indicator keeps flashing, and at the same time, the control unit transmits the continuous vibration command to the vibration motor to make it vibrate continuously, reminding the owner that the door has not been locked successfully;

When the unlock button is pressed, the unlock command is transmitted to the control unit, and then the unlock command is sent through the wireless communication module. At the same time, the control unit will continue to light up for two seconds and transmit the command to the door unlocked indicator/battery status indicator to keep it on. Light up for two seconds, if the wireless communication module receives the unlocked command returned by the car control system within two seconds, the unlocked command is transmitted to the control unit, and the control unit transmits the off command to the door unlocked indicator/battery status indicator for use. It is off, if the wireless communication module does not receive the unlocked command returned by the car control system within two seconds, when no unlocked command is transmitted to the control unit, the control unit will continue to flash for ten seconds and transmit the command to the door unlocked indicator/battery The status indicator light keeps flashing for ten seconds and then goes out;

When the button to open the trunk is pressed, the instruction to open the trunk is transmitted to the control unit, and then the instruction to open the trunk is sent through the wireless communication module. The opened command is transmitted to the control unit, and the control unit transmits the continuous lighting command to the tail box unlocked indicator/battery status indicator to keep it on. After the boot is closed, the car control system sends a boot closed command. , the wireless communication module receives the tail box closed command returned by the car control system and transmits it to the control unit, and the control unit transmits the extinguishing command to the tail box unlocked indicator/battery status indicator to make it go out, and the wireless communication module is on When no boot closed command is received from the vehicle control system within 90 seconds, no boot closed command is transmitted to the control unit, and the control unit transmits the continuous flashing command to the tail box unlocked indicator light/battery status The indicator light makes it flash continuously, and at the same time, the control unit transmits the periodic vibration command to the vibration motor to make it vibrate periodically, reminding the owner that the trunk of the car has not been locked successfully;
