Abstract

The invention provides a door lock device for vehicles, wherein the device is low in cost, simple in structure and better in protection performance for passengers during the lateral collision process. A lower connection part (51) of a rod (50) is connected with the lower end of an up-down extension part (57). The lower connection part (51) comprises a horizontal extension part (54) bent substantially along the horizontal direction from the lower end of the up-down extension part (57); and an insertion part (53) configured to extend downwardly from the end portion of the horizontal extension part (54) to be inserted into an insertion hole (36). The insertion part (53) comprises a large-diameter part (71) embedded in the insertion hole (36) through a guiding part (37); and a small-diameter part (72) configured to extend continuously and downwardly from the lower end of the large-diameter part (71). The upper end portion of the small-diameter part (72) is provided with a conic section (72a) configured to face the large-diameter part (71) and diverge at the tail end thereof. A linear-shaped linear part (72b) is configured to extend downwardly from the lower end of the conic section (72a).

Description

technical field [0001] The present invention relates to an improvement of a vehicle door lock device provided on a vehicle body and a vehicle door. Background technique [0002] There is known a vehicle door lock device that unlocks the door by actuating a latch unit via a lever by pulling the outside door handle (for example, refer to Patent Document 1( image 3 )). [0003] The vehicle door lock device disclosed in Patent Document 1 includes a latch unit capable of locking and unlocking movement on a vehicle door, and an outside door handle for performing unlocking operation of the latch unit. The latch unit is used to perform latching and latching-unlocking movements of a striker (striker) provided on the vehicle body. [0004] When the door outer handle is released, a lever connected to the door outer handle is pushed down, and the lever pushes down a lock release lever of the latch unit, thereby unlocking the latch unit. [0005] based on Figure 13 The outline of Pa...
