Abstract

The invention discloses an automobile intelligent key which comprises an intelligent key part and an automobile-mounted part. The automobile-mounted part comprises a radio frequency charging circuit and an intelligent on-off circuit which are both arranged at the bottom of an automobile article storage box. The radio frequency charging circuit is provided with a radio frequency charging output coil in a connected manner. The intelligent key part comprises an on-off device, an intelligent key inner controller, a rechargeable lithium battery, a radio frequency receiving coil, a charging power management circuit and a radio frequency charging receiving circuit. The controlled end of the on-off device is connected to the output end of the intelligent key inner controller. According to the automobile intelligent key, through the manner that a traditional lithium battery which cannot be charged is replaced with the rechargeable lithium battery, the automobile intelligent key can be used durably, the battery does not need to be replaced, operation is quite convenient, and the charging efficiency is greatly increased; and manual plugging of a charging cable head is not needed, and operation is quite convenient.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to an automobile intelligent key. Background technique [0002] In the automotive field, there are currently three types of car keys. 1. Mechanical metal key. Use the traditional mechanical way, open or close the car door with the metal key, start the engine or stop the engine with the metal key. 2. Mechanical metal key with remote control. On the basis of the metal key, an electronic remote control for remotely locking the car door is added. At present, almost all passenger cars are equipped with remote locking and opening functions, but the traditional mechanical key is still required to start the engine. The remote control only works at the moment when the door is opened or locked, and is usually not working at all. 3. Car smart key. The car smart key has the remote lock and unlock function of the remote key to the car door lock; at the same time, it c...
