Hood hinge structure

Abstract

The present invention provides a hood hinge structure, including a hinge base fixed to the vehicle body; a shock absorber arranged on the hinge base; and a hinge arm rotatably supported by the hinge base to support the hood to open / close to the vehicle body, and having a curved portion to avoid abutting on a member on the vehicle body side when the hood is opened to the vehicle body. The hinge arm rotates to a curving side of the curved portion to be engaged with the shock absorber, when the collision from the vehicle body front side or the collision from the vehicle body upper side to the hood is caused.

Description

technical field [0001] The present invention relates to a hood hinge structure for assembling a hood to a body of a vehicle (for example, an automobile, etc.) in an openable and closable manner. Background technique [0002] In vehicles (eg, automobiles, etc.), a hood hinge is used to openably and closably assemble a hood to a body of the vehicle. So far, many technologies have been proposed on hood hinges to protect pedestrians in the event of a vehicle collision (for example, Patent Document 1 to Patent Document 3). [0003] As these techniques, in order for a hood hinge (the hood hinge including a hinge arm fixed to the hood and a hinge bracket fixed to the vehicle body to rotatably support the hinge arm) to absorb the shock applied by a collision from the vehicle body Occurs toward the hood in the upward direction), as an example, a deformed structure using a hinge arm (for example, see Patent Document 1 to Patent Document 3) or a deformed structure using a hinge bracke...

Problems solved by technology

However, it seems that since this structure needs to have high rigidity in order to protect the occupants, the performance of absorbing the shock applied by the collision is low
