Abstract

The present invention provides a locking device for a vehicle, which can eliminate the adhesion caused by freezing between a movable contact and a fixed contact under the condition of not causing durableness decrease or cost increase. According to the present invention, the locking device is configured to comprise a first locking hook (120), a second hook (130), an auxiliary rod (150) and a switch, wherein the switch can detect locking according to the contact between the movable contact (thin rod 174) and the fixed contact (172), the movable contact is an elastically-deformable metal thin sheet supported in a cantilever state, the auxiliary rod (150) is provided with a projection (156), when firing pins are separated, the projection (156) rotates in a direction opposite to an offset direction and runs into the opening end side of the movable contact, and the movable contact and the fixed contact (172) are separated.

Description

technical field [0001] The present invention relates to a vehicle lock device installed in an automobile or the like. Background technique [0002] To ensure safety, cars detect the open / closed state of open / closed parts such as hoods and doors. For example, Patent Document 1 discloses a hood latch provided with a switch that detects the open / close state of the hood. Furthermore, Patent Document 2 discloses a door striker (a door lock device) provided with a switch that detects an open / closed state of a vehicle door. [0003] As described in Patent Document 3, generally, an automobile hood latch includes a latch (first hook), a post (second hook), and an auxiliary lever. The latch and post secure the striker by operating the hood latch cable from inside the passenger compartment. The auxiliary lever is a backup device for securing the striker so that the hood does not open even when the hood lock cable is accidentally operated. Release the assist lever manually by insert...
