Abstract
The present invention relates to an override structure of an automobile door latch, in which an arc-shaped slot (2a) formed in the inside handle lever (2) and an actuator lever (6a) connection side portion of the lock lever (5) are connected by an override rod (9). It features.
Therefore, when the inside handle is operated, the lock lever 5 is rotated by the override rod 9, and the actuator lever 6a is interlocked, and the safety lock lever connected thereto is operated to release the safety lock state. The door can be opened without manipulating the lock lever.
Description
BACKGROUND OF THE
The door of the vehicle should be closed stably while driving, and should be unlocked and opened by manipulating the inside handles and the outside handles provided inside / outside the door.
A door latch for performing such a function is shown in FIG. 1, which includes an
Therefore, when opening the door in the normally closed state, the
On the other hand, a function of allowing the lock state to be released by only pulling the inside handle without operating the safety lock knob during the above release operation is called an override, and the conventional low-cost door latch does not have such an override function.
Accordingly, there is a need for an implementation of an override function for improving passenger convenience.
Accordingly, the present invention has been invented in view of the above-mentioned issues, and the override function is implemented so that the occupant does not need to operate the safety lock knob when the door is opened, so that the convenience of the door opening is further improved. The purpose is to provide a structure.
The present invention for achieving the above object,
The inside handle lever and the outside handle lever rotatably installed on the base plate, the open lever interlocked with the inside handle lever and the outside handle lever, the lock lever rotatably fixed to the lower side of the base plate, and the lock lever rotated. In the door latch of the vehicle comprising an actuator to be connected to the lock lever, the lower end is connected to the slot of the lower handle lever, the child handle lever is selectively interlocked with the inside handle lever,
The inside handle lever and the lock lever are characterized in that connected by an override rod.
The upper end of the overdrive rod is connected to an arc-shaped slot formed in the inside handle lever.
In addition, the end portion of the open lever is extended and is characterized by being rotated by the child lock lever.
By the above configuration, the lock lever is interlocked and the lock state is released when the inside handle is operated, thereby eliminating the need to separately operate the safety lock knob when the occupant opens the locked door.
That is, the override function is implemented, thereby making it easier to release the door lock state through the inside handle operation, thereby improving the convenience of the user.
Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.
