The utility model discloses a limiting-type lock catch power device for an electronic intelligent lock, and the device comprises a motor base, a motor, a motor drive control board, a power supply, a lock catch contact piece, a lock cylinder opening limiting piece, and a lock cylinder closing limiting piece, and a lock catch cooperating with a lock cylinder. The motor is disposed in the motor base, and the output shaft of the motor is connected with the lock catch. The motor base is provided with a lock catch movement groove which is matched with the movement track of the lock catch. The lock catch is movably disposed in the lock catch movement groove. The lock catch contact piece is electrically connected with the lock catch. The lock cylinder opening limiting piece is disposed at the head part of the lock catch movement groove on the motor base. When the motor operates to enable the lock catch to be located at the head part of the lock catch movement groove, the lock catch electrically contacts with the lock cylinder opening limiting piece. The lock cylinder closing limiting piece is disposed at the tail end of the lock catch movement groove on the motor base. When the motor operates to enable the lock catch to be located at the tail end of the lock catch movement groove, the lock catch electrically contacts with the lock cylinder closing limiting piece. The device provided by the utility model achieves a function of power-failure protection when the lock catch is in place, guarantees the accurate arrival of the lock catch, and prolongs the service life of the electronic intelligent lock.
