본 발명은 보행자 보호를 위한 자동차용 엔진커버 고정 어셈블리에 관한 것으로서, 보다 상세하게는 보행자와 충돌시 발생되는 충격력에 의해서 엔진커버가 이동될 수 있도록 엔진커버의 고정부에 판 스프링을 내장한 보행자 보호를 위한 자동차용 엔진커버 고정 어셈블리에 관한 것이다.The present invention relates to an engine cover fixing assembly for automobiles for pedestrian protection, and more particularly, to protect pedestrians incorporating a leaf spring in the fixed part of the engine cover so that the engine cover can be moved by an impact force generated when a pedestrian collides with. An engine cover fixing assembly for a vehicle.

일반적으로 자동차에는 엔진룸을 보호하면서 엔진소음에 대한 차음기능도 겸하도록 된 후드가 구비되는 바, 이러한 후드는 카울톱 아우터에 힌지를 매개로 회동되며 차내에 있는 버튼 또는 레버에 와이어를 매개로 연결되어 그 버튼 또는 레버의 조작에 따라 와이어가 당겨짐으로써 후드의 록킹이 해제되는 구조를 갖는다.In general, a car is equipped with a hood that protects the engine room and also serves as sound insulation for engine noise, which is pivoted through the hinge to the cowl top outer and connected to the button or lever in the car via a wire. And the locking of the hood is released by pulling the wire according to the operation of the button or the lever.

후드는 후드래치 및 안전후크에 의하여 2단으로 록킹되는 구조를 가지므로 록킹된 후드를 해제하기 위해서는 후드래치를 먼저 록킹 해제시키고 다음에 수동으로 안전후크를 작동시켜야 비로소 후드를 개방시킬 수 있다.Since the hood has a structure that is locked in two stages by the hood latch and the safety hook, in order to release the locked hood, the hood latch must first be unlocked and then the safety hook can be manually operated to open the hood.

이렇게 후드가 2단 잠김구조를 갖는 것은 혹시라도 후드래치가 완전히 록킹되지 않은 상태로 주행을 하다가 주행풍에 의해 후드가 갑자기 열리는 것을 방지하기 위한 것이다.The hood has a two-stage locking structure to prevent the hood from being suddenly opened by the driving wind while driving while the hood latch is not completely locked.

한편, 후드에 의해서 보호된 엔진룸의 내부에는 엔진이 설치되어 있되, 그 엔진의 표면에는 엔진에서 발생되는 소음과 진동을 최대한 줄여줌으로써, 차량의 승차감을 좋게 하면서도 엔진에서 발생되는 고열을 차단하여, 엔진의 열기로 인한 주변 부품의 손상을 방지하기 위한 엔진커버가 설치되어 있다.On the other hand, the engine is installed inside the engine room protected by the hood, but the surface of the engine by reducing the noise and vibration generated by the engine as possible, to improve the ride comfort of the vehicle while blocking the high heat generated by the engine, An engine cover is installed to prevent damage to peripheral components due to engine heat.

종래에는 도1에 나타낸 바와 같이 엔진커버(100)를 고정하고 있다.Conventionally, the engine cover 100 is fixed as shown in FIG.

여기에서 참조되는 바와 같이 엔진(140)의 표면을 차단하는 엔진커버(100)에 는 수용홈(110)이 형성되어 있고, 그 수용홈(110)의 저부에는 엔진에서 발생되는 진동을 완충하기 위한 완충부재(120)가 설치되어 있다.As described herein, the accommodating groove 110 is formed in the engine cover 100 that blocks the surface of the engine 140, and the bottom of the accommodating groove 110 is configured to buffer vibration generated in the engine. The buffer member 120 is provided.
