Drawings
Fig. 1 schematically shows a schematic structural diagram of the present invention.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
The utility model discloses an aspect provides a car key with lock car and remind function, include: the key control circuit is used for sending a vehicle locking signal and a vehicle unlocking signal to the vehicle; an RFID detection circuit for generating a first signal when an RFID tag within the vehicle terminal is not detected; the electric quantity alarm lamp is used for sending a light alarm signal; the buzzer is used for sending out a sound alarm signal; the controller is electrically connected with the key control circuit, the Bluetooth communication circuit, the electric quantity alarm lamp and the buzzer; the first signal triggers the controller to start the electric quantity alarm lamp and the buzzer, and the vehicle locking signal triggers the controller to close the electric quantity alarm lamp and the buzzer.
Preferably, the car key with the function of reminding of locking still includes the casing, be provided with the spare battery on the casing and hold the chamber, spare battery holds and deposits the spare battery in the chamber. Thus, when the battery is exhausted, the spare battery in the spare battery accommodating cavity can be taken out to replace the battery.
The RFID detection circuit and the key control circuit are well known in the art and will not be described further herein.
During the use, when the user leaves the vehicle, but when not pressing the key of locking a car of key, the RFID detection circuitry in the car key can not detect the RFID label in the vehicle to generate first signal, then trigger the controller and start electric quantity alarm lamp and bee calling organ, forget the lock car with the warning user. When a user presses a vehicle locking key outside the vehicle, the key control circuit sends a vehicle locking signal, so that the controller is triggered to turn off the electric quantity alarm lamp and the buzzer.
Since the technical scheme is used, the utility model discloses can conveniently remind the user to forget the lock car, bring the convenience for the user, have simple structure, characteristics with low costs.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
