The invention discloses a locking mechanism with a self-return function. The locking mechanism with the self-return function comprises a motor, a worm, a worm gear, a pawl, a lock-tongue, a pawl torsional spring, a lock-tongue torsional spring, a lock-tongue rivet, a pawl rivet and a rotating shaft; the lock-tongue is rotatably installed on the lock-tongue rivet and is provided with the lock-tongue torsional spring on the lock-tongue rivet in a sleeving mode, and the side face of the lock-tongue is provided with a limiting groove; the pawl is rotatably installed on the pawl rivet and is provided with the pawl torsional spring on the pawl rivet in a sleeving mode, the pawl rivet is located at the first end of the pawl, the side face of the pawl is provided with buckles matched with the limiting groove, the buckles and the limiting groove are oppositely arranged, and the second end of the pawl is provided with protruding blocks; the worm is rotatably installed on the rotating shaft, and buffering blocks matched with the protruding blocks are arranged on the worm gear; the worm is arranged on an output shaft of the motor, and the worm is meshed with the worm gear. By means of the locking mechanism with the self-return function, the number of spare parts is reduced, and the production cost is effectively reduced.
