Door lock device for vehicle

Abstract

The purpose of this invention is to provide a door lock device for a vehicle enabling one motion operation and keyless lock operation and capable of preventing increase of operation load from the halfway of door opening operation in a vehicle room to enhance operation property and simplifying its structure. This door lock device for the vehicle is constituted in such a way that a pressure receiving part 86a capable of abutting the other end of a pressing link 87 is provided at the outer periphery of an intermediate lever 86, a guide projection 91 is protrusively provided on a support member 57 supporting the intermediate lever 86 turnably and made of synthetic resin, and the pressing link 87 which is energized by a spring so as to come into slide-contact with the guide projection 91 and whose one end is turnably connected with an inside handle lever 61 is displaced to a position where abutting on the pressure receiving part 86a is released while guided by the guide projection 91 in accordance with further turn of the inside handle lever 61 after turning the intermediate lever 86 from a lock position to an unlock position.

Description

technical field [0001] The present invention relates to a door lock device for a vehicle, in particular, even if the door is in a locked state, the door can be unlocked by performing a door opening operation on an inner handle in a vehicle compartment (so-called one-shot operation), And, when the door is in the open state, pull out the outer handle or inner handle outside the compartment, perform the locking operation of the lock button, and then close the door to make it in the locked state (so-called keyless locking operation). lock device. Background technique [0002] A door lock device for a vehicle capable of one-operation operation and keyless locking operation is disclosed in, for example, Patent Document 1 or the like. [0003] Patent Document 1 Japanese Patent Publication No. 6-63395 [0004] However, in order to perform both one-action operation and keyless locking operation, it is necessary to adopt such a structure that one end of the push link is connected to...

AI Technical Summary

Problems solved by technology

Therefore, after the pushing force of the pressing link no longer acts on the intermediate lever, the operating load for opening the door in the compartment increases sharply, and there are some problems in operability

Moreover, in the above-mentioned existing structure, in addition to setting the shaft for contacting and engaging the pressing rod on the intermediate rod, the above-mentioned guide shaft must be arranged on the pressing link rod, which not only complicates the structure, but also increases the cost.
