Description

기밀성을 향상시킨 차량용 엔진 후드의 가스리프터{An automotive engine hood having a gas lifter for improving seal }An automotive engine hood having a gas lifter for improving seal}

본 발명은 기밀성을 향상시킨 차량용 엔진 후드의 가스리프터에 관한 것으로, 보다 상세하게는 국부적인 선 접촉 부위를 형성하여 고압에 대한 기밀성을 향상시킨 차량용 엔진 후드의 가스리프터에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas lifter for a vehicle engine hood having improved airtightness, and more particularly to a gas lifter for a vehicle engine hood having a local line contact portion to improve airtightness against high pressure.

일반적으로 차량의 엔진룸을 가려 엔진과 기타 장치들을 보호하는 엔진 후드는 엔진이나 기타 장치들을 정비하도록 필요시 한쪽부위를 위로 올려 개·폐할 수 있게 되고, 이 때 도 1에 도시된 바와 같이 위로 올려진 엔진 후드(H)를 지지하여 열려진 상태를 유지하도록 양쪽부위에 지지장치를 구비하게 된다.In general, the engine hood that covers the engine compartment of the vehicle to protect the engine and other devices can be opened and closed by lifting one part up as necessary to service the engine or other devices. Supporting devices are provided at both sides to support the engine hood H and remain open.

여기서, 상기 지지장치는 통상, 내부로 질소가스를 충진시킨 가스리프터(1)를 사용하여 가스를 매개로 무거운 엔진 후드(H)를 지지하고 닫을 때 엔진 후드(H)의 닫힘 속도를 저감시켜 안정적으로 개·폐할 수 있게 된다.Here, the support device is generally stable by reducing the closing speed of the engine hood (H) when supporting and closing the heavy engine hood (H) via the gas using a gas lifter (1) filled with nitrogen gas inside. I can open and close it.

이 때, 상기 가스리프터(1)는 도 2에 도시된 바와 같이 엔진 후드(H)쪽에 고정되어 엔진 후드(H)의 개·폐에 따른 속도를 조절하도록 가스를 충진한 하우징(2)과, 이 하우징(2)내로 삽입되면서 차체측에 고정된 로드(5) 로 구성되되, 상기 하우징(2)은 로드(5)의 끝단에 구비된 피스톤(5a)에 의해 충진된 가스가 이동되면서 그 영역이 가변 되는 제1·2챔버(2a,2b)로 나누어짐과 더불어 이 제1챔버(2a)부위에 기밀부재(3)와 가이더(4)가 구비되어 진다.At this time, the gas lifter 1 is fixed to the engine hood (H) side as shown in Figure 2 filled with gas to adjust the speed according to the opening and closing of the engine hood (H), and It is composed of a rod 5 fixed to the vehicle body side while being inserted into the housing 2, the housing 2 is a region of the gas filled by the piston (5a) provided at the end of the rod 5 is moved In addition to the variable first and second chambers 2a and 2b, the airtight member 3 and the guider 4 are provided at the first chamber 2a.

여기서, 상기 기밀부재(3)는 도 3에 도시된 바와 같이 하우징(1)의 내경에 접촉되는 외경접촉면(3a)과 로드(5)의 외경에 접촉되는 내경접촉면(3b)으로 이루어져 내부가스의 유출을 방지하게 됨은 물론이다.Here, the airtight member 3 consists of an outer diameter contact surface 3a in contact with the inner diameter of the housing 1 and an inner diameter contact surface 3b in contact with the outer diameter of the rod 5 as shown in FIG. 3. Of course it will prevent leakage.

그러나, 이와 같은 가스리프터(1)의 하우징(2)내에 충진된 가스의 온도가 상승되면 이로 인해 하우징(1)내의 압력이 증가되면서 기밀부재(3)에 작용하는 압력도 증가되어, 기밀부재(3)의 외경접촉면(3a)와 내경접촉면(3b)의 접촉부위가 고르게 분포되지 않게 되고 이에 따라, 장시간 사용시 기밀부재(3)의 기밀성이 저하되어 가스의 누출이 발생되는 등의 성능 저하 현상을 야기하는 문제가 있게 된다.However, when the temperature of the gas filled in the housing 2 of the gas lifter 1 rises, the pressure in the housing 1 increases, thereby increasing the pressure acting on the airtight member 3, thereby increasing the pressure of the gastight member ( The contact area between the outer diameter contact surface 3a and the inner diameter contact surface 3b of 3) is not evenly distributed, thereby degrading the performance such as the gastightness of the airtight member 3 deteriorating when gas is used for a long time. There is a problem that causes it.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 기밀부재의 선 접촉 부위가 가스 압력의 증가에 따라 함께 증가되면서 기밀성을 높여 가스의 누출을 방지함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and the purpose is to prevent the leakage of gas by increasing the airtightness while the line contact portion of the airtight member increases with the increase of the gas pressure.

상기와 같은 목적을 달성하기 위한 본 발명은, 가스리프터가 엔진 후드쪽에 고정되어 엔진 후드의 개·폐에 따른 속도를 조절하도록 충진된 가스가 이동되면서 그 영역이 가변 되는 제1·2챔버로 이루어진 하우징과, 이 하우징을 피스톤을 매개로 제1·2챔버로 양분하면서 차체 측에 고정된 로드 및 상기 하우징에 삽입된 가이더의 전단으로 구비되어 내부의 기밀을 유지하도록 하우징의 내경과 로드의 외경에 각각 선접촉되는 기밀부재로 이루어지는 것을 특징으로 한다.The present invention for achieving the above object, the gas lifter is fixed to the engine hood side is made up of the first and second chambers that the area is changed while the gas filled to adjust the speed according to the opening and closing of the engine hood The housing and the rod fixed to the vehicle body side by dividing the housing into the first and second chambers via a piston, and the front end of the guider inserted into the housing, so that the inner diameter of the housing and the outer diameter of the rod are maintained so as to maintain the airtightness therein. Characterized in that each consisting of a hermetic member in line contact.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 4는 본 발명에 따른 가스리프터에 사용된 기밀부재의 부분 확대도를 도시한 것인바, 본 발명의 가스리프터(1)는 엔진 후드(H)쪽에 고정되어 엔진 후드(H)의 개·폐에 따른 속도를 조절하도록 충진된 가스가 이동되면서 그 영역이 가변 되는 제1·2챔버(2a,2b)로 이루어진 하우징(2)과, 이 하우징(2)을 피스톤(5a)을 매개로제1·2챔버(2a,2b)로 양분하면서 차체 측에 고정된 로드(5) 및 상기 하우징(2)에 삽입된 가이더(4)의 전단으로 구비되어 내부의 기밀을 유지하도록 하우징(2)의 내경과 로드(5)의 외경에 각각 선접촉되는 기밀부재(3)로 이루어진다.Figure 4 shows a partial enlarged view of the airtight member used in the gas lifter according to the present invention, the gas lifter 1 of the present invention is fixed to the engine hood (H) side opening and closing of the engine hood (H) And a housing (2) consisting of first and second chambers (2a, 2b) whose area is varied while the gas filled to adjust the speed is moved, and the housing (2) is connected via a piston (5a). The inner diameter of the housing 2 is provided with a front end of the rod 5 fixed to the vehicle body side and the guider 4 inserted into the housing 2 while dividing into two chambers 2a and 2b. It consists of the airtight member 3 line-contacted with the outer diameter of the rod 5, respectively.

여기서, 상기 기밀부재(3)의 외경접촉면(3a)은 하우징(1)의 내경에 선 접촉되도록 그 중앙부위가 돌출 됨과 더불어 내경접촉면(3b)도 로드(5)의 외경에 선 접촉되도록 그 중앙부위가 돌출 되어진다.Here, the outer diameter contact surface (3a) of the airtight member 3 is protruded so that the center portion is in contact with the inner diameter of the housing (1) and the inner diameter contact surface (3b) is also in the center so that the outer diameter of the rod (5) The area protrudes.

이에 따라, 가스리프터(1)의 하우징(2)내에 충진된 가스의 압력이 정상적인 압력을 유지하게 되면 기밀부재(3)의 외·내경접촉면(3a,3b)이 모두 돌출된 부위만이 접촉되지만 만약, 내부가스의 온도가 상승하여 압력이 증가되면 이 압력을 받게 되는 기밀부재(3)가 어느 정도 팽창하면서 외·내경접촉면(3a,3b)이 각각 하우징(2)의 내경과 로드(5)의 외경으로 확대되어 지게 된다.Accordingly, when the pressure of the gas filled in the housing 2 of the gas lifter 1 maintains the normal pressure, only the portion where the outer and inner diameter contact surfaces 3a and 3b of the airtight member 3 protrude from each other is in contact. If the temperature of the inner gas rises and the pressure increases, the airtight member 3 subjected to this pressure expands to some extent, and the outer and inner diameter contact surfaces 3a and 3b respectively have an inner diameter and a rod 5 of the housing 2. It will be enlarged to the outer diameter of.

이로 인해, 상기 기밀부재(3)의 외·내경접촉면(3a,3b)이 하우징(2)내의 가스압력 상승에 따라 더욱 밀착 접촉되어 기밀도를 높여 주게 됨은 물론이다.Therefore, the outer and inner diameter contact surfaces 3a and 3b of the airtight member 3 are brought into close contact with each other as the gas pressure in the housing 2 rises, thereby increasing the airtightness.

이상 설명한 바와 같이 본 발명에 의하면, 기밀부재의 선 접촉 부위가 가스 압력의 증가에 따라 함께 증가되면서 기밀성을 높여 가스의 누출을 방지함은 물론 성능저하를 방지하는 효과가 있게 된다.As described above, according to the present invention, the line contact portion of the airtight member is increased together with the increase in the gas pressure, thereby increasing the airtightness and preventing the leakage of the gas as well as the performance degradation.
