The integrated vehicle door lock comprises the following working processes:

one, external opening function

As shown in fig. 10, the outward opening function is realized by connecting the outer handle of the vehicle door and the outward opening rocker arm 12 on the lock body through a pull rod or a pull cable. When the outer handle of the vehicle door is pulled by an external force, the outer handle is pulled to drive the outward-opening rocker arm 12 to rotate around the pawl shaft, the outward-opening rocker arm 12 is of a plate-shaped three-step structure and is provided with a central hole 121 and a side hole 122, the lower horizontal part of the outward-opening rocker arm is sleeved on the pawl shaft and is positioned above the lock body 1, the central hole 121 of the middle horizontal part is just abutted against the left side surface (contact surface 1) of the outward-opening linkage arm 13, the outward-opening linkage arm 13 is pushed to rotate when the outward-opening rocker arm 12 rotates, the outward-opening linkage arm 13 rotates to drive the pawl baffle shaft 11 positioned below the outward-opening linkage arm to rotate (contact surface 2), the pawl baffle shaft 11 is riveted on the pawl 10, the pawl baffle shaft rotates to drive the pawl 10 to rotate and recede, so that the ratchet rotates, a lock catch. When the external handle assembly of the vehicle door is loosened, the external-open rocker arm automatically returns under the action of the external-open return spring.

Two, external locking and unlocking functions

As shown in fig. 11, the external locking and unlocking functions are realized by connecting the door lock cylinder with an external locking rocker arm 20 on the lock body through a pull rod. When the lock core assembly is rotated by a key, a pull rod on the lock core assembly drives an outer locking rocker arm 20 to rotate around a shell 2, so that an outer locking linkage arm 19 (a contact surface 3) connected to the outer locking rocker arm 20 drives a locking linkage arm 18 to rotate, the locking linkage arm 18 is sleeved on a fixed shaft extending upwards and vertically on a lock body, the locking linkage arm 18 is connected with a locking shifting arm 17 as shown in a figure 6, the locking linkage arm 18 rotates to drive the locking shifting arm 17 to rotate, the locking shifting arm 17 rotates to drive an outer opening linkage arm 13 to rotate (a contact surface 4), so that a pawl baffle shaft 11 is separated from the contact surface 2, and the outer opening linkage arm 13 rotates to be incapable of driving a pawl 10 to rotate and yield, so that the purpose of locking is achieved; the lock core assembly is rotated by a key, so that the outward-opening linkage arm 13 can drive the pawl 10 to rotate and give way, and the purpose of unlocking is achieved.

Triple, inward opening forced opening function

As shown in figure 12, the inward opening forced opening function is realized by connecting the door inner handle and the inward opening rocker arm 14 on the lock body through a pull cable. When the inner handle of the car door is pulled by external force, the inner handle is pulled by a pull rope to drive the inner opening rocker 14 to rotate around a fixed shaft which is positioned on the shell and vertically extends upwards, the other end of the inner opening rocker 14 abuts against an arc-shaped notch (contact surface 5) which extends from the right lower part of the side surface of the electric rocker 16 so as to drive the electric rocker 16 to rotate, a flange 161 is arranged on the lower side wall of the electric rocker 16 and is clamped in a square groove 171 of the locking shifting arm 17 to drive the locking shifting arm 17 to rotate, the locking shifting arm 17 moves to drive the locking linkage arm 18 to move and unlock, meanwhile, the inner opening rocker 14 drives the inner opening linkage arm 15 to rotate (contact surface 6), the inner opening linkage arm 15 pushes a pawl blocking shaft 11 riveted on the pawl 10 to move and yield, the connection relationship is shown in a figure 5, at the moment. When the handle assembly in the vehicle door is loosened, the inward opening rocker arm automatically returns under the action of the inward opening return spring.

Fourth, electric locking and unlocking function

As shown in fig. 13, when the motor 34 is energized in the forward direction, the worm 35 on the motor shaft rotates to drive the dual gear 36 engaged with the worm 35 to rotate, and at the same time, the electric rocker arm 16 engaged with the dual gear 36 is driven to rotate, a flange 161 is arranged on the lower side wall of the electric rocker arm 16 and is engaged with the square groove 171 of the locking toggle arm 17 to drive the locking toggle arm 17 to rotate, the locking toggle arm 17 rotates to drive the outward-opening linkage arm 13 to rotate, so that the pawl stop shaft 11 is separated from the contact surface 2, and the outward-opening linkage arm 13 rotates and cannot drive the pawl 10 to rotate and yield, thereby achieving the function of electric locking, as shown in fig. 14.

The motor 34 is energized reversely, the worm 35 on the motor shaft rotates to drive the dual gear 36 engaged with the worm 35 to rotate, and simultaneously drive the electric rocker arm 16 engaged with the dual gear 36 to rotate, a flange 161 is arranged on the lower side wall of the electric rocker arm 16 and is clamped in the square groove 171 of the locking shifting arm 17 to drive the locking shifting arm 17 to rotate, the locking shifting arm 17 rotates to drive the outward opening linkage arm 13 to rotate, so that the pawl baffle shaft 11 is separated from the contact surface 2, and the outward opening linkage arm 13 rotates to drive the pawl 10 to rotate and yield, thereby achieving the function of electric unlocking, such as the state shown in fig. 15.

Fifthly, false locking prevention function

As shown in fig. 16, the anti-mislocking function means that the door cannot be locked when the door is open, and the locking function is disabled when the door is open. When the ratchet wheel 7 is in the full-open position and the locking linkage arm 18 is in the unlocking position, the limiting block 702 protruding from the side wall of the ratchet wheel blocks the locking linkage arm 18 from rotating, and the function of preventing mistaken locking is achieved.
