<p>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).</p> |
