It relates to an integrated module of a power distribution device for a vehicle.

근래에는 가솔린이나 디젤을 연료로 사용하는 내연엔진은 대기를 오염시키기 때문에 선진국을 중심으로 한 세계각국은 친환경 자동차 개발을 위한 치열한 경쟁을 하고 있으며 각 자동차 제조사들은 친환경, 고효율의 첨단기술을 필요로 하는 미래형 자동차의 기술개발 경쟁에서 뒤쳐지지 않도록 많은 노력들을 하고 있다.In recent years, internal combustion engines that use gasoline or diesel as fuel pollute the air, so countries around the world, including developed countries, are in fierce competition to develop eco-friendly vehicles. We are making great efforts not to be left behind in the technology development competition for future cars.

특히, 직면한 화석연료의 고갈 문제를 해결하면서 보다 친환경적인 제품을 개발해야 한다는 시대적 요청에 부응하여 최근 각 자동차 제조사들은 전기모터를 동력원으로 사용하는 전기자동차에 대한 연구를 더욱 활발히 진행하고 있다.In particular, in response to the demands of the times to develop more eco-friendly products while solving the problem of depletion of fossil fuels, automobile manufacturers are more actively conducting research on electric vehicles using electric motors as power sources.

이처럼 전기모터를 작동시켜 차량을 구동시키는 전기자동차에는 전기모터의 구동전력을 제공하는 고전압 배터리가 필수적으로 장착되며 고전압 배터리는 차량 운행 중에 충/방전을 반복하면서 필요한 전력을 공급하게 된다.As such, an electric vehicle that operates an electric motor to drive the vehicle is equipped with a high-voltage battery that provides driving power for the electric motor.

그리고 전기자동차에는 배터리가 외부 전력공급으로부터 충전이 가능하도록 완속충전기(On Board Charger)가 설치되고, 완속충전기에 의해 충전된 전력을 모아서 고전압 배터리 및 각 전장부품으로 인가하기 위한 전력 분배장치가 설치된다.In addition, an on-board charger is installed in the electric vehicle so that the battery can be charged from an external power supply, and a power distribution device is installed to collect the power charged by the slow charger and apply it to the high-voltage battery and each electronic component. .

상기 완속충전기와 전력분배장치가 설치된 전기자동차의 선행기술이 대한민국 특허청 특허등록 제 10-1404395호에 개시되어 있다.The prior art of an electric vehicle in which the slow charger and the power distribution device are installed is disclosed in Patent Registration No. 10-1404395 of the Korean Intellectual Property Office.

This can be prevented in advance, and since the slow charger and the power distribution device can be fixed with one bracket, the parts cost is reduced and the number of work hours is reduced, thereby shortening the work time and improving the productivity. .

그러나 선행기술에서의 전기자동차에서는 완속충전기와 전력분배장치 그리고 전력분배장치와 저전압 배터리 충전용 로우DC컨버터를 모두 커넥터와 케이블을 이용하여 연결하기 때문에 중량이 많이 나가는 것은 물론 이들을 각각 설치하기 위한 공간확보에 어려움이 있다.However, in electric vehicles in the prior art, since the slow charger, the power distribution device, and the power distribution device and the low DC converter for charging the low voltage battery are all connected using connectors and cables, they are not only heavy in weight but also secure space to install them. there are difficulties in

상기처럼 완속충전기(400)를 하우징(100)의 함체 하층부(120)에 버스바(121)로 접속되게 설치하면 이 역시 종래 사용하던 컨넥터와 와이어를 삭제할 수 있어 중량이 감소되는 것이다.When the slow charger 400 is installed to be connected to the lower layer portion 120 of the housing 100 by the bus bar 121 as described above, the conventional connector and wire can be deleted, thereby reducing the weight.

상기 결착수단으로는 완속충전기(400)의 일측벽의 프론트와 리어측 양단에는 체결홀(421)과 가이드핀(422)이 있는 체결부(420)를 구비하고, 함체 하층부(120) 일측벽의 프론트와 리어측 양단에는 가이드핀(422)이 끼워지는 핀홀(125)과 체결홀(421)에 볼팅되는 볼팅홀(126)이 있는 브라켓(124)을 구비하였다.As the fastening means, a fastening part 420 having a fastening hole 421 and a guide pin 422 is provided at both ends of the front and rear sides of one side wall of the slow charger 400, Brackets 124 having pinholes 125 through which the guide pins 422 are fitted and bolting holes 126 bolted to the fastening holes 421 are provided at both ends of the front and rear sides.

그리고 버스바(121)가 있는 함체 하층부(120)의 일측벽 상부에는 함체 상층부(110)에 의한 처마부(122)를 구비하고 처마부(122)의 선단에는 보스체결홀(123)을 다수 구비하고 완속충전기(400)의 덮개(410)에는 보스체결홀(123)과 체결되는 보스(411)를 다수 구비하였다.And the upper part of one side wall of the lower part 120 of the housing having the bus bar 121 is provided with the eaves 122 by the upper part of the housing 110, and a plurality of boss fastening holes 123 are provided at the front end of the eaves 122. And the cover 410 of the slow charger 400 was provided with a plurality of bosses 411 fastened to the boss fastening hole 123.

따라서 완속충전기(400)를 전력 분배장치(200)와 저전압 배터리 충전용 로우DC컨버터(300)가 내장된 하우징(100)에 일체형으로 설치하기 위해서는 우선 완속충전기(400)의 일측벽이 함체 상층부(110)의 처마부(122)에 위치시켜 함체 하층부(120)에 돌출 형성된 버스바(121)가 완속충전기(400)의 버스바홀(401)에 끼워지게 한 후 완속충전기(400)의 체결부(420)를 함체 하층부(120)의 브라켓(124)에 밀착되게 한다.Therefore, in order to integrally install the slow charger 400 in the housing 100 in which the power distribution device 200 and the low-voltage battery charging low DC converter 300 are built in, first, one side wall of the slow charger 400 is the upper part of the housing ( The fastening part of the slow charger 400 after being positioned on the eaves 122 of 110 and the bus bar 121 protruding from the housing lower layer 120 is fitted into the bus bar hole 401 of the slow charger 400 ( 420) to be in close contact with the bracket 124 of the lower layer portion 120 of the housing.

그런데 상기 체결부(420)에는 체결홀(421)과 가이드핀(422)이 구비되고 브라켓(124)에는 핀홀(125)과 볼팅홀(126)이 구비되어 있으므로 가이드핀(422)은 핀홀(125)속으로 끼워지게 하고 체결홀(421)은 볼팅홀(126)과 일치되게 한 후 볼트를 체결홀(421)과 볼팅홀(126)을 관통되게 체결하여 주면 된다.However, since the fastening part 420 is provided with a fastening hole 421 and a guide pin 422 , and the bracket 124 is provided with a pinhole 125 and a bolting hole 126 , the guide pin 422 is a pinhole 125 . ) and make the fastening hole 421 coincide with the bolting hole 126 , and then fasten the bolt through the fastening hole 421 and the bolting hole 126 .

이처럼 완속충전기(400)의 일측벽을 함체 하층부(120)에 결합한 후 완속충전기(400)의 덮개(410)에 구비된 다수의 보스(411)를 처마부(122)의 선단에 구비된 보스체결홀(123)과 일치시킨 후 이 역시 볼팅 체결하여 주면 완속충전기(400)는 하우징(100)에 일체형으로 통합되는 것이고, 즉, 전력 분배장치(200)와 로우DC컨버터(300), 완속충전기(400)가 하나의 컴팩트한 사이즈의 통합 모듈로 이루어지는 것이다.As such, after coupling one side wall of the slow charger 400 to the lower housing unit 120 , a plurality of bosses 411 provided in the cover 410 of the slow charger 400 are fastened to the boss provided at the tip of the eaves 122 . After matching with the hole 123, this is also bolted to the main surface, and the slow charger 400 is integrally integrated into the housing 100, that is, the power distribution device 200 and the low DC converter 300, the slow charger ( 400) is composed of an integrated module of one compact size.

이처럼 컴팩트한 사이즈의 통합 모듈로 구성하게 되면 협소한 공간에서 설치하기 위한 공간을 확보하는데 유리한 것이다.If it is composed of an integrated module of such a compact size, it is advantageous to secure a space for installation in a narrow space.

또한, 본 발명에서는 상기처럼 결착수단에 의해 결착된 하우징(100)과 완속충전기(400)의 테두리에 행거(430)를 최소 3점 이상 구비하여 통합된 모듈을 리프팅할 때 안정적으로 리프팅할 수 있도록 한다.In addition, in the present invention, a hanger 430 is provided on the rim of the housing 100 and the slow charger 400 bound by the binding means as described above, so that at least three points are provided so that the integrated module can be lifted stably when lifting. do.

이상 본 발명자에 의해서 이루어진 발명을 상기 실시 예에 따라 구체적으로 설명하였지만, 본 발명은 상기 실시 예에 한정되는 것은 아니고 그 요지를 이탈하지 않는 범위에서 여러 가지로 변경 가능한 것은 이 기술분야에서 통상의 지식을 가진 자에게 자명하다 할 것이다.Although the invention made by the present inventor has been described in detail according to the above embodiment, the present invention is not limited to the above embodiment and it is common knowledge in the art that various changes can be made without departing from the gist of the present invention.
