Description

씨엔지 차량의 연료 통 보호수단{A fuel tank protector of CNG vehicle }A fuel tank protector of CNG vehicle

본 발명은 씨엔지 차량의 연료 통 보호수단에 관한 것으로, 보다 상세하게는 측면 충돌 시 충격을 완화하여 폭발의 위험을 방지하면서 정비성을 향상시킬 수 있도록 된 씨엔지 차량의 연료 통 보호수단에 관한 것이다.The present invention relates to a fuel tank protecting means of the CNG vehicle, and more particularly, to a fuel tank protecting means of the CNG vehicle which can improve the maintainability while preventing the risk of explosion by mitigating the impact during side impact. will be.

일반적으로, 압축천연가스인 CNG(Compressed Natural Gas)를 연료로 사용하는 차량은 현재 여러 가지 단점에도 불구하고 저렴한 연료비와 저공해 배기가스로인해 사용이 증가되고 있으며 또한 지속적인 개발이 이루어 지고 있는 추세이다.In general, vehicles that use compressed natural gas (CNG) as a fuel are increasing in use due to low fuel cost and low pollution exhaust gas despite various disadvantages, and are continuously being developed.

도 1은 이와 같은 씨엔지 차량을 나타낸 것으로서, 연료 통(F)이 차체의 측면 하단부위에 격자 형상으로 이루어진 프레임박스(I)내로 수용되어 밸브기구(도시되어 있지 않음)를 통해 엔진으로 연료를 공급하게 된다.FIG. 1 illustrates such a CNG vehicle, in which a fuel tank F is accommodated in a frame box I formed in a lattice shape at a lower side of a side of a vehicle body to supply fuel to an engine through a valve mechanism (not shown). Done.

그러나, 이와 같은 압축천연가스(CNG)는 폭발의 위험성이 큰 가스 연료로서 특히, 차량의 측면에 위치된 연료 통(F)이 장착된 프레임박스(I)로 충격이 가해져 연료 통(F)의 밸브부위가 파손되는 경우, 파손된 밸브를 통해 연료 통(F)의 가스가 누출되어 주위의 불꽃에 의해 폭발하게 되는 가장 큰 문제가 있게 되고, 이에 따라 충격이 가해지더라도 연료 통(F)의 밸브부위의 파손을 방지할 수 있는 보호수단의 개발이 절실히 요구되고 있는 실정이다.However, such compressed natural gas (CNG) is a gas fuel having a high risk of explosion, and in particular, an impact is applied to the frame box (I) in which the fuel container (F) located on the side of the vehicle is impacted. If the valve part is damaged, the biggest problem is that the gas in the fuel container F leaks through the broken valve and is exploded by the surrounding flame, so that even if an impact is applied, the valve of the fuel container F is damaged. There is an urgent need for the development of protective means to prevent damage to the site.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 차량의 측면에 구비된 연료 통의 밸브부위로 가해지는 충격을 흡수·완화하여 밸브의 파손을 방지함은 물론 착·탈을 용이하게 하여 정비를 간편하고 용이하게 할 수 있도록 함에 그 목적이 있다.In view of the above, the present invention has been invented, and the shock applied to the valve portion of the fuel container provided on the side of the vehicle is absorbed and mitigated to prevent damage to the valve as well as to facilitate attachment and detachment. The purpose is to make maintenance simple and easy.

상기와 같은 목적을 달성하기 위한 본 발명은, 연료 통을 장착한 프레임박스의 양 측면을 이루는 측면프레임에 이 측면프레임을 가로질러 연료 통의 밸브부위를 보호하도록 그 끝단에 보올트와 같은 고정부재를 매개로 장착되는 프로텍터로 구성되는 것을 특징으로 한다.The present invention for achieving the above object, a fixing member such as a bolt at the end to protect the valve portion of the fuel container across the side frame to the side frame forming both sides of the frame box equipped with the fuel container Characterized in that consists of a protector mounted via the.

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 2는 본 발명에 따라 연료통 보호수단이 장착된 씨엔지 차량의 개략도를 도시한 것인바, 본 발명은 전술한 바와 같이 연료 통(F)이 차체의 측면 하단부위에 격자 형상으로 이루어진 프레임박스(I)내로 수용되되, 이 프레임박스(I)와 연료 통(F)사이에 연료 통(F)의 밸브부위를 보호하는 보호수단이 구비되어진다.Figure 2 shows a schematic view of the CNG vehicle equipped with fuel tank protection means according to the present invention, the present invention is the frame box (I) is a fuel box (F) made of a lattice shape on the lower side of the side of the vehicle body as described above (I) It is accommodated in the), between the frame box (I) and the fuel container (F) is provided with a protective means for protecting the valve portion of the fuel container (F).

여기서, 상기 보호수단은 차체의 길이방향으로 설치된 프레임박스(I)의 양 측면에 구비된 측면프레임(1,1')을 가로질러 구비되는 프로텍터(2)와, 이 프로텍터(2)를 고정·결합하는 고정부재(2)로 이루어진다.Here, the protection means is a protector (2) provided across the side frames (1, 1 ') provided on both sides of the frame box (I) installed in the longitudinal direction of the vehicle body, and fixing the protector (2) It consists of a fixing member (2) for coupling.

그리고, 상기 프로텍터(2)는 도 3에 도시된 바와 같이 돌출 된 중앙부위를 중심으로 그 양 쪽이 함몰되어 대칭형상을 이루면서 전체적으로 동일한 두께를 갖추게 된다.In addition, the protector 2 has the same thickness as the center of the protruding center portion as shown in FIG.

또한, 상기 고정부재(3)는 프로텍터(2)를 프레임박스(I)의 측면프레임(1,1')에 고정됨과 더불어 분리가 용이하도록 보올트로 이루어지며, 이 보올트는 프로텍터(2)가 측면프레임(1,1')에 견고하게 장착되도록 프로텍터(2)의 돌출 된 중앙부위와 그 양 쪽의 함몰부에 사용하게 된다.In addition, the fixing member 3 is fixed to the protector (2) to the side frame (1, 1 ') of the frame box (I) and made of a bowl for easy separation, the protector (2) is the side of the protector (2) In order to be firmly mounted on the frame (1, 1 '), it is used for the protruding center portion of the protector (2) and the depressions on both sides thereof.

따라서, 전술한 종래와 같이 씨엔지 차량의 연료 통(F)을 장착하기 위한 프레임박스(I)가 제작된 상태에서 본 발명의 프로텍터(2)를 고정부재(3)인 보올트를 이용하여 프레임박스(I)를 이루는 측면프레임(1,1')에 고정하게 되므로, 프로텍터(2)의 장착을 위한 설계변경이나 구조변경이 없이 간단히 장착되어지게 됨은 물론이다.Accordingly, as described above, the protector 2 of the present invention is framed using a bolt, which is the fixing member 3, in the state where the frame box I for mounting the fuel tank F of the CNG vehicle is manufactured. Since it is fixed to the side frame (1, 1 ') constituting the box (I), it is, of course, to be simply mounted without a design change or structural change for mounting the protector (2).

이와 같이, 상기 프레임박스(I)의 측면프레임(1,1')을 가로질러 연료 통(F)의 밸브기구부위를 가리도록 프로텍터(2)가 설치되므로 만약, 타 차량이 차체의 측면에 충돌하더라도 프레임박스(I)의 측면프레임(1,1')을 가로질러 설치된 프로텍터(2)가 충격을 흡수하면서 완화시켜 연료 통(F)의 밸브부위와 연료 공급 파이프등의 훼손이나 파괴를 방지하게 된다.In this way, since the protector 2 is installed to cover the valve mechanism portion of the fuel container F across the side frames 1 and 1 'of the frame box I, if another vehicle collides with the side of the vehicle body. Even though the protectors 2 installed across the side frames 1 and 1 'of the frame box I absorb shocks, they are alleviated to prevent damage or destruction of the valve portion of the fuel container F and the fuel supply pipe. do.

이상 설명한 바와 같이 본 발명에 의하면, 차량의 측면에 구비된 연료 통의 밸브부위로 가해지는 충격을 흡수·완화하여 밸브의 파손을 방지함은 물론 착·탈을 용이하게 하여 정비를 간편하고 용이하게 할 수 있는 효과가 있게 된다.As described above, according to the present invention, the shock applied to the valve portion of the fuel tank provided on the side of the vehicle is absorbed and mitigated to prevent damage to the valve, as well as to facilitate attachment and detachment, thereby making maintenance simple and easy. It will work.
