Manufacturing method of commercial vehicle door lock structure

1. The present invention relates to a door lock for commercial vehicles, especially a door lock structure.

Background technique:

2. With the advancement of electronic control technology, more and more electronic control technologies are used on commercial vehicle doors, such as: electronically controlled door locks, electronically controlled glass lifts, electronically controlled rearview mirror retraction, angle adjustment, heating, etc. The opening and closing of the guest lights, etc., the adoption of these electronic control technologies has greatly improved the automation of commercial vehicle door control and improved the comfort of commercial vehicles.

3. Electric-controlled door locks usually use a motor as a power to drive the lock tongue to unlock the door. Because the lock tongue needs to be able to be locked again after unlocking, the unlocking drive mechanism should be ready for unlocking again, and cannot interfere with the movement of the lock tongue before re-locking. can not interfere with each other. Chinese patent cn215632334u discloses an unlocking control mechanism for an automobile lock. The mechanism uses a rocker arm as an output device, and uses a rope to connect the rocker arm and the latch mechanism. The rocker arm and the transmission mechanism between the rocker arm and the motor are respectively provided with rocker arms Return spring and turbo return spring. Using the rope connection, although the force transmission and the non-interference between the locking action of the latch and the unlocking control mechanism can be achieved, it is obviously not as accurate and stable as the rigid structure in force and action transmission, and the flexible connection cannot lock the lock. The locking action of the tongue is completely isolated from the unlocking control mechanism. In addition, the complex structure of the vehicle lock unlocking control mechanism will not only increase the cost, but also increase the difficulty of assembly and the probability of failure.
