Description

Stay wire distributor for automobile door lock

Technical Field

The utility model belongs to the technical field of automobiles, and particularly relates to a stay wire distributor for an automobile door lock.

Background

In the field of automobile opening and closing parts, a typical application scenario is that when two door locks (L1, L2) are required to be configured for one opening and closing body (for example, a vehicle door, a front hatch, a trunk lid, etc.), the two door locks are required to work synchronously, i.e., to unlock and close the door synchronously or to self-suction and close the door synchronously. Two door locks on the opening and closing body are necessarily arranged at a relatively far position due to the function realization of the opening and closing body and the consideration of the overall strength. Based on the cost, the two are usually connected by using a pull rope, and the same driving operation mechanism A can be used for executing the synchronous work manually or electrically to realize the function of an opening and closing body.

Figures 3,4,5,6 illustrate a typical use of the mechanism a to transmit an operating force to the dispenser B via a pull wire and further to transmit mechanical movement to the locks L1 and L2 via a pull wire to achieve synchronized operation of the locks L1 and L2. I.e. to unlock the door synchronously or to self-suction the door synchronously.

However, when one operating mechanism a is used to operate two door locks (L1, L2), one door lock (e.g., L1) must be operated first due to objective reasons such as tolerance stack-up and torque distribution, but the operating mechanism a must continue to operate to drive the other door lock (e.g., L2) to operate. In this process, the conventional design causes the door lock L1 to over-travel in the first completed motion. And the realization of the over-travel needs to consume relatively large energy, so that the possibility of completing the action of the other door lock L2 is reduced, and meanwhile, the additional performance requirement is also provided for the operating mechanism A.
