A left pawl limiting shaft on the bottom plane of the lock body base plate is provided with a locking rocker arm. The pawl limiting shaft penetrates through the lock body base plate and the locking rocker arm to be riveted with the lock body cover plate. One end of the locking rocker arm is punched into a right angle and is right arranged in a groove in the lower end of a center control box, and the other end of the locking rocker arm is inserted into a groove formed in an externally-opened rocker arm. The externally-opened rocker arm is arranged on the vertical plane of the lock body base plate. An electric push rod is fixed behind the bottom plane of the lock body base plate, and is connected with an automobile center control system. A sloping plate located on the horizontal plane is arranged on the rear portion of a pawl. The sloping plate faces the rear right side, and an open groove is formed in the end of the sloping plate. The opening size of the open groove is larger than the external diameter of a push rod body of the electric push rod. The front door lock body assembly is convenient and flexible to operate, simple, attractive, low in cost and good in quality. The function of delayed locking after unlocking is achieved, and application and popularization have good economic benefits and social benefits.
