Abstract

The task of the invention aims to provide a vehicle door lock device which can reduce structural components, simplify structures, and reduce the amplitude and weight in a thickness direction, and aims to reduce production cost. The vehicle door lock device comprises a latch mechanism (13) which can release snap joint of a firing pin (10) of a vehicle body; an opening rod (40) which can be axially arranged on a motor casing in a rotary mode; one side of a shaft portion is driven by a motor driving mechanism, and through a linkage portion one the other side of the shaft portion, the latch mechanism (13) moves to release the firing pin (10), wherein the opening rod (40) is configured in such a way that one side of a shaft portion (41) is provided with an arc concave slot portion (42) with the shaft portion (41) as a center, and the concave slot portion (42) is internally provided with a gear; the gear is engaged with a connecting gear (19) of the motor driving mechanism; in addition, one side of the shaft portion (41) of the opening rod (40) is provided with a manual operation part (40a) capable of being operation in a vehicle.

Description

technical field [0001] The present invention relates to a door latch arrangement for holding a rear door of a vehicle in a closed position. Background technique [0002] Figure 8 It is a schematic diagram showing a door latch device installed on a rear door of an automobile such as a passenger car. [0003] In addition, this figure shows the state in which the door latch device engages with the striker 10 of a vehicle body, and holds the closed position of a rear door. [0004] The above-mentioned door latch device includes a well-known latch mechanism 13 composed of a fork 11 and a claw 12 . [0005] In addition, the fork 11 is rotatably supported by a base plate (not shown) via a shaft 14 , and the fork 11 receives a clockwise rotational force via a return spring. [0006] The claw 12 is rotatably supported on the base plate through the shaft 15. In addition, the claw 12 receives the counterclockwise rotation force through the return spring, and in the state where the f...
