The invention discloses an electronic lock. The electronic lock comprises a lock assembly, a lock electric control assembly, a latch assembly and a latch hook assembly, wherein the latch hook assembly comprises a latch hook, a latch hook support and a latch shaft; the latch hook is rotatably positioned and supported on the latch hook support, while the latch shaft is translationally supported on the latch hook support; a bolt and the lock electric control assembly both are in unlocking/locking connection with the latch hook and the latch assembly orderly through the latch shaft; the latch shaft is provided with a return spring, while the latch hook is provided with a torsional spring and a latch mounting part; the latch hook is in linkage connection with the latch through the latch mounting part. And therefore, the mechanical element design of the electronic lock is ingenious, the lock assembly and the lock electric control assembly share the same lock cylinder (the latch hook assembly) so that unlocking/locking operations can be performed on the latch assembly, and the existing lock structure is effectively simplified.
