본 고안은 차량용 본네트 개폐장치에 관한 것으로, 특히 차량의 본네트가 소정각도로 회동되어 열려지게되면 별도의 보조기구가 사용되지 않고도 자동적으로 본네트가 열려진 상태로 걸려지도록 된 차량용 본네트 개폐장치에 관한 것이다.The present invention relates to a bonnet switchgear for a vehicle, and more particularly, to a bonnet switchgear for the vehicle is to be automatically caught in the open state without the use of a separate auxiliary mechanism when the bonnet of the vehicle is rotated at a predetermined angle.

일반적으로 차량의 엔진실은 본네트로 덮여져 내부에 설치된 엔진등이 보호되도록 되어 있는바, 엔진에 이상이 있다거나 엔진동작의 이상유무를 점검하는 경우 또는 냉각수나 오일등을 보충하기 위해 본네트를 열게된다.In general, the engine compartment of the vehicle is covered with a bonnet to protect the engines installed inside. The engine is opened to check the engine for abnormalities or to check the engine for abnormal operation, or to supplement the coolant or oil. .

이렇게 본네트를 여는 경우 일반적으로 본네트를 앞.뒤 또는 좌, 우중 한쪽을 회전중심으로 들어올려 열도록 되어 있는바, 즉 종래의 차량용의 본네트는 그 양쪽 측면이 각각 2개의 링크를 매개로 엔지룸 양편 가아드 상부부근에 연결시켜진 구조로 되어 있어서, 엔진룸을 개방시키기 위해서는 본네트를 들어올려 이를 한쪽으로 완전히 젖히거나 소정각도로 들어올린 다음 지지부재로 받쳐 열린상태가 유지되도록 하여야 하였다. 이 경우본네트를 한쪽으로 젖히는 경우에는, 본네트와 엔지룸 가아드를 연결하는 링크에 큰 인장하중과 충격하중이 걸리게 되어 상기 링크와 이 링크가 설치되는 본네트 및 측면가아드부위에 구조적인 변형이 일어나게 될뿐 만아니라, 상기 본네트를 덮을려면 본네트를 다시 들어올린 다음 닫아야 하기 때문에 힘이 들게된다. 한편 지지부재로 받쳐주는 경우에는 반드시 별도의 지지부재가 필요하게 될 뿐만 아니라, 본네트가 소정각도로 들어 올려 열려진 상태에서 잠시동안이지만 이를 손으로 붙잡고 본네트와 측면 가아드사이에 지지부재를 걷어 고정시켜야 하는 조작상의 불편이 있었다.In the case of opening the bonnet, the bonnet is generally opened by lifting one of the front, back, left, and right sides of the rotation center, i.e., in the case of the conventional vehicle bonnet, both sides of the engine are connected to each other through two links. Since the structure is connected to the upper part of the guard, in order to open the engine room, the bonnet should be lifted up and fully flipped to one side or lifted at a predetermined angle, and then supported by a support member to maintain the open state. In this case, when the bonnet is flipped to one side, a large tensile load and an impact load are applied to the link connecting the bonnet and the engine guard, and structural deformation occurs at the link and the bonnet and the side guard portion where the link is installed. In addition, to cover the bonnet, it is difficult to lift and close the bonnet again. On the other hand, when supporting with a support member, not only a separate support member is necessary, but also the bonnet is lifted at a predetermined angle for a while, but it is held for a while, and the support member must be fixed by rolling the support member between the bonnet and the side guard. There was an inconvenience in operation.

이에 본 고안은 상기와 같은 제반 불편을 해소하기 위해 안출된 것으로, 트랙터의 본네트와 엔진실 측면가아드를 연결하는 양쪽링크에 그 길이방향을 따라 한쪽끝이 구부려진 길다란 안내구멍이 형성됨과 더불어 이 안내구멍속에 상기 측면가아드 또는 본네트에 구비된 보조링크의 이동핀이 삽입시켜 지도록 되면서, 본네트를 열게되면 상기 이동핀이 링크에 형성된 안내구멍을 따라 이동하다가 이 안내구멍 선단에 굴곡되어 형성시켜진 걸림홈에 걸리게 되어 본네트가 열려진 상태를 고정되게 유지시킬 수 있도록 되어 있다. 따라서 이상과 같은 구성에 의해 본네트를 힘들이지 않고 개폐할 수가 있게 되고, 연결링크를 보호할 수 있옴은 물론, 별도의 지지부재등이 필요치 않은 본네트 개폐장치를 제공할 수가 있게 된다.The present invention has been devised to solve the above-mentioned inconveniences, and a long guide hole having one end bent along its length is formed in both links connecting the bonnet of the tractor and the engine compartment side guard. The moving pin of the auxiliary link provided in the side guard or the bonnet is inserted into the hole, and when the bonnet is opened, the moving pin moves along the guide hole formed in the link and is bent at the tip of the guide hole. It is caught in the and the bonnet is kept open. Therefore, the above configuration enables the bonnet to be opened and closed effortlessly, to protect the connection link, as well as to provide a bonnet opening and closing device that does not require a separate support member.
