Electronic lockset for carrying out contact coupling and power supply on lock body by key

The invention provides an electronic lockset for carrying out contact coupling and power supply on a lock body by a key, aiming at a plurality of defects of the existing electronic locket for providing electronic power support on the lock body by the key and controlling to unlock that a naked electrode contact manner is used for transmitting power and data so that poor electrode contact is easy to generate, the electronic locket cannot be used in inflammable and explosive environments and environment with water, manual technical damages cannot be prevented and the like. The electronic lockset adopts a mutually-contacted electromagnetic coupling manner to provide the electronic power support to the lock body by the key and transmit (password or fingerprint) identification data to execute unlocking control, so that the problem of poor electrode contact is not caused and the condition that the naked electrode is manually damaged or an inner electronic device is viciously damaged by input strong power does not ex
