Description

COVER OPENING PREVENTION APPARATUS FOR A VEHICLE’S TRAY

The present invention relates to cover opening prevention apparatus for a vehicle’s tray, and more particularly, to technology to prevent the lock status of a vehicle’s tray from being released and opened due to an external impact.

A tray of a vehicle is, in general, equipped with a housing that stores objects and a cover that opens and closes the front opening of the said housing, wherein the cover is configured to be able to rotate around, in order to open and close, the front opening of the housing.

Also, in general, a cover locking device is to be provided to the said cover that rotates for opening and closing for the purpose of securing the lock status of the cover.

It is important to steadfastly secure the said lock status of a cover to prevent objects from falling out of the housing, which may impair the safety of the passengers, when the cover is opened due to a collision while driving.

For example, Korean Registered Utility Model Publication No. 20-0440039 for a tray fixing structure for an automobile discloses, as a method to maintain the lock status of a tray as aforementioned by controlling the tray movement at a location inside the place to which the tray contacts, a locking device that is fitted, on a surface of the housing, with a heart cam equipped with a fixing pin protruding outwards and controls the heart cam movement by means of frictional resistance of an oil ring.

Technologies have been published as such to ameliorate the safety of such products which render a fixing pin, which serves as a locking unit, move along the trajectory of a heart cam when the cover is opened and closed and prohibit, by means of an oil ring, the displacement of the fixing pin placed in the heart cam even in case of an external impact.

However, in case that the oil ring, which provides a relevant damping effect, is damaged decreasing its fictional resistance, a usual impact while driving may release the lock status rendering the cover be open, which has been criticized as a drawback of those existing technologies aforementioned.
