일반적으로 전기자동차는 자동차의 소음 및 배출가스 등의 공해문제를 해결할뿐만아니라, 에너지 절약과 관련된 잉여전력의 유효한 이용과, 장래의 새로운 교통수단으로 적용하는데 목표를 두고 세계각국에서 적극적으로 연구개발을 실시하고 있다.In general, electric vehicles not only solve the pollution problem such as noise and emission of automobiles, but also actively research and development in various countries with the goal of effectively using surplus power related to energy saving and applying it as a new means of transportation in the future. We carry out.

전술한 바와같은 전기자동차는 축전지에 충전된 전기를 연료로 사용하여 전동기를 구동시키는 원리로 되어있다.As described above, the electric vehicle has a principle of driving an electric motor by using electricity charged in a battery as a fuel.

한편 전기자동차의 엔진룸내에는 고전압의 축전지와 모터제어기가 설치되며 상기 축전지와 모터제어기 사이에는 전원을 차단 및 연결시켜주는 전원개폐기가 설치되게 된다.Meanwhile, a high voltage battery and a motor controller are installed in the engine room of the electric vehicle, and a power switch for disconnecting and connecting power is installed between the battery and the motor controller.

이와같은 전원개폐기는 전원을 직접적으로 차단 및 연결하는 컨넥터와 이를 구동하는 구동회로 그리고 퓨즈 등으로 구성된다.Such a power switch is composed of a connector that directly cuts off and connects the power, a driving circuit for driving the fuse, and a fuse.

이러한 전기자동차용 전원개폐기는 도 4에 도시된 바와같이 엔진룸(1)내의 축전지와 모터제어기 사이에 설치된 케이스(10)와, 상기 케이스(10) 내부에 설치되어 전원을 차단 및 연결하는 컨넥터(11)와, 상기 컨넥터(11)의 측면 소정부위에 구동회로기판(12)를 설치하여 구성된다.As shown in FIG. 4, a power switch for an electric vehicle includes a case 10 installed between a battery and a motor controller in an engine room 1 and a connector installed inside the case 10 to cut off and connect power. 11) and a drive circuit board 12 are provided on a predetermined side surface of the connector 11.

이와같이 구성된 종래 전기자동차용 전원개폐기는 엔진룸(1)내의 축전지와 모터제어기 사이에 케이스(10)를 고정설치한후, 상기 케이스(10) 내부에 전원을 차단 및 연결하는 컨넥터(11)를 설치한다. 그리고 상기 컨넥터(11) 측면 소정부위에는 구동회로기판(12)을 취부시키도록 한다.In the conventional electric vehicle power switch configured as described above, the case 10 is fixedly installed between the battery and the motor controller in the engine room 1, and then the connector 11 is installed in the case 10 to cut off and connect the power. do. In addition, the driving circuit board 12 is mounted on a predetermined portion of the connector 11 side.

상기 케이스(10)는 뚜껑(16)에 의해 덮혀져 필요시에만 상기 뚜껑(16)을 개방시킨후 점검 및 수리작업을 하게 된다.The case 10 is covered by a lid 16 to open the lid 16 only when necessary, and then perform inspection and repair work.

한편 상기와 같이 케이스(10)내의 컨넥터(11)와 구동회로기판(12) 등으로 구성된 전원개폐기는 단순한 기능과 간단한 구조로 되어있지만 상당히 높은 직류전압이 인가되어 있는 상태이므로 취급에 주의를 요한다.On the other hand, the power switch is composed of a connector 11 and the driving circuit board 12, etc. in the case 10 as described above, but has a simple function and simple structure, but requires a great care of handling because a fairly high DC voltage is applied.

전술한 바와같은 전기자동차용 전원개폐기는 케이스 내부의 바닥면에 컨넥터와 구동회로기판을 동일하게 설치시킴에 따라 케이스 내부공간이 과다하게 소요되어 케이스의 부피가 커지게 된다.As described above, the power switch for an electric vehicle, as the connector and the driving circuit board are installed on the bottom surface of the case in the same way, the internal space of the case is excessively increased, thereby increasing the volume of the case.

그러나 케이스내의 전원개폐기는 비좁은 엔진룸내에 배치되어야 하므로 소형화 되어야 하는데 상기와 같이 부피가 큰 케이스는 엔진룸내에 설치하는데 공간을 많이 차지하여 차량 엔진룸의 레이아웃성 및 공간활용이 저하될뿐아니라, 무리하게 케이스를 소형화할 경우 점검 및 수리작업시 타부품에 간섭을 주어 위험하고 정비성이 저하되는 등의 문제점이 있다.However, since the power switch in the case should be placed in a narrow engine room, it should be miniaturized. As described above, the bulky case occupies a lot of space to install in the engine room, which not only reduces the layout and space utilization of the vehicle engine room. In the case of miniaturizing the case, there is a problem such as dangerous and poor maintenance due to interference with other parts during inspection and repair work.

따라서 본 고안의 목적은 전기자동차의 엔진룸내에 설치된 전원개폐기에 있어, 상기 전원개폐기가 설치된 케이스의 일측 벽면에 개폐가 용이한 도어를 설치한후, 상기 도어 내측면에 구동회로기판을 취부시켜 케이스의 바닥면에는 컨넥터만 설치함에 따라 케이스를 소형화 하기 위한 전기자동차용 전원개폐기를 제공하는데 있다.Accordingly, an object of the present invention is to provide a power switch in an engine room of an electric vehicle, and to install an easy opening / closing door on one side wall of the case in which the power switch is installed, and then installing a driving circuit board on the inner surface of the door The sole of the connector is to provide a power switch for electric vehicles to downsize the case by installing only the connector.
