Benefits of technology

This patent is about a hinge for a trunk lid that compensates for any deterioration in the amount of springing caused by plastic deformation. The hinge allows the user to adjust the position or rotation angle of the spring so that the amount of elastic deformation is increased when the lid is closed. This results in a more robust and adjustable hinge for trunk lids.

Problems solved by technology

However, there is a problem in that elastic restoring force of the torsion spring 3 deteriorates due to repetitive torsion as time passed, and plastic deformation of the torsion spring 3 occurs.
Furthermore, when the pop-up amount is decreased, a sensor cannot sense an opening signal of the trunk lid 1, and a result, an indicating lamp for indicating an opened state of the trunk lid 1 is likely to be erroneously operated on an instrument panel.

Abstract

A hinge apparatus for a trunk lid may include a hinge arm which has a first end rotatably coupled to a vehicle body, and a second end fixed to the trunk lid, and a spring which may be mounted to and supported by the vehicle body, connected with the hinge arm, and elastically deformed by rotation of the hinge arm when the trunk lid may be closed, in which a position or a rotation angle at a point at which the spring may be supported by the vehicle body may be adjusted so that an amount of elastic deformation of the spring may be increased when the trunk lid may be closed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority to Korean Patent Application No. 10-2014-124988, filed on Sep. 19, 2014, the entire contents of which is incorporated herein for all purposes by this reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a hinge apparatus for a trunk lid, and more particularly, to a hinge apparatus for a trunk lid, which is configured to compensate for deterioration in opening force for the trunk lid even though the opening force deteriorates due to plastic deformation of a spring.[0004]2. Description of Related Art[0005]As illustrated in FIG. 1, a trunk room of a passenger vehicle is a space at a rear side of the vehicle for accommodating luggage, and a trunk lid 1 is rotatably mounted to a vehicle body, thereby opening and closing the trunk room.[0006]A shape of a trunk lid 1 is variously designed in accordance with the type of vehicle and the shape classificati...
