Abstract
본 고안은 전기자동차에 관한 것이다.
종래의 전기자동차는 가고 오는 차선마다 별도의 송선을 가설해야 하는 경제적 부담이 컸고, 배터리 전기자동차는 도로변에 충전소를 설치하는 경제적 부담뿐만 아니라 충전시간이 너무 길고 자주 충전하는 번거로운 결점이 있었다.
그리고 하이브리드(hybrid) 자동차는 연비개선을 위한 복합 동력으로서 차량의 생산원가가 높아 친환경이 미흡한 결점을 지니고 있다.
본 고안은 도로변의 중앙분리대 선상에 비교적 낮게 가설된 병열의 송전선에, 승용차, 버스 등 각종 자동차의 운전석 쪽 천장(지붕) 상면 양측에 설치한 가늘고 긴 스프링포올(spring pole) 선단의 활접봉(滑接棒)이 자동으로 접촉케 하여 전력공급을 받으면서 고속주행케 하는 것이다.

이상과 같이 본 고안은 중앙분리대 선상의 낮은 전주(1)에 상하 병렬로 가설한 송전선에서, 1차선에서 왕래하는 차량이 공동으로 수전할 수 있게 하였으므로 송전선 가설의 비용이 종래방식의 50%정도로 크게 절감되는 효과가 있고 도로변에 충전소를 설치할 필요가 없고 차량운행비 및 차량생산원가도 저렴하여 실용성이 매우 높다.The present invention relates to an electric vehicle.
Conventional electric vehicles have a high economic burden to install a separate transmission line for each lane coming and going, battery electric vehicles have not only the economic burden of installing a charging station on the road side, but also the charging time is too long and cumbersome defects of frequent charging.
In addition, hybrid vehicles are a complex power for improving fuel efficiency and have a disadvantage in that the environment is inadequate due to the high production cost of the vehicle.
The present invention is a sliding rod of a long and thin spring pole end installed on both sides of the ceiling of the driver's seat of various automobiles such as passenger cars and buses on the transmission line of the parallel line laid on the line of the center divider on the roadside. I) to make high speed driving while receiving power supply.
Battery can be charged while driving, driving fare is reduced, vehicle production cost is greatly reduced, and it is 100% environmentally friendly.
As described above, the present invention allows a vehicle traveling in one lane to receive power jointly in a transmission line constructed in parallel up and down on a low pole (1) on a median line, so that the cost of the transmission line construction is about 50% of the conventional method. It has the effect of saving, there is no need to install the charging station on the side of the road, and the vehicle operation cost and the vehicle production cost are also low, the practicality is very high.
Description
본 고안은 도로면의 중앙분리대 선상에 비교적 낮게 가설한 송전선에서 승용차, 버스 등 각종 자동차가 직접 전력공급을 받아 전기모터(electric motor)에 의하여 고속주행하면서 배터리(battery)에 충전할 수 있게 한 것이다.The present invention is to make it possible to charge a battery while driving at high speed by an electric motor by receiving various types of automobiles, buses, etc. directly from the power line installed on the center divider line of the road surface. .
종래의 전기자동차는 가고 오는 차선마다 송전선을 부설하였기 때문에 공사비 부담이 큰 결점이 있었고 배터리 전기차는 도로변에 충전소를 설치해야 하기 때문에 공사비가 방대하고 충전시간이 너무 길고 충전빈도가 많아서 너무 번거로워 실용성이 낮은 결점이 있었다.The conventional electric vehicle has a drawback in that the construction cost burden is great because the transmission line is laid in every lane coming and going, and the battery electric vehicle has to install a charging station near the road, so the construction cost is enormous, the charging time is too long and the charging frequency is too cumbersome and the practicality is low. There was a flaw.
본 고안 전기자동차는 도로변에 충전소 설치가 필요없고 종래의 송전선 설치비보다 50% 정도로 저렴한 송전선에서 전력공급을 받아 고속주행하면서 배터리 충전이 가능하고 주행운임 및 차량 생산원가가 저렴하고 100% 친환경이고 승하차(乘下車)를 편리케 하여 실용성을 높게 하는 것을 연구과제로 한다.The electric vehicle of the present invention does not need to install a charging station on the side of the road, and it is possible to charge the battery while driving at high speed by receiving power from a power transmission line that is about 50% cheaper than a conventional transmission line installation cost, and the driving fare and vehicle production cost are low, 100% eco-friendly and getting on and off ( It is a research project to make convenience and increase practicality.
도로의 중앙분리대 선상의 낮은 전주에 가설한 송전선에서 전력공급을 받아 고속으로 주행하면서 배터리(battery)에도 충전 할 수 있게 하고 차량의 송전선 시설이 없는 도로에서는 배터리 동력만으로 운행 할 수 있게 한다.Power is supplied from the power line installed on the low pole of the road in the middle of the road, so that it can be charged at a high speed while driving at high speed.
본 고안은 지하철과 같은 레일없이 지상 도로면에서 자유롭게 운행할 수 있는 전기자동차로서 100% 친환경이고 하이브리드(hybrid)차와 같은 가솔린엔진과 발전기가 없어서 구조가 간단하고 중량 및 부피가 적고 생산원가가 저렴하고 고속주행이 가능하고 주행운임이 저렴하고 또 주행하면서 배터리(battery)에 충전이 가능하므로 도로변에 충전소 설치가 필요없고 도로의 중앙 분리대에 설치한 일정한 간격의 낮은 전주에 송전선을 상하병렬로 가설하여 가는 차량과 오는 차량이 공동으로 수전하므로 송전선 길이가 종래방식보다 50%정도 절감되어 경제성과 실용성이 매우 높다.The present invention is an electric vehicle that can operate freely on the ground road without a rail such as subway, and is 100% eco-friendly and there is no gasoline engine and generator like a hybrid car, so its structure is simple, its weight and volume are low, and its production cost is low. It is possible to drive at high speed, and the driving fare is cheap, and it is possible to charge the battery while driving, so there is no need to install a charging station on the side of the road. Since the incoming and outgoing vehicles receive power jointly, the transmission line length is reduced by 50% compared to the conventional method, and the economic and practicality are very high.

도로면의 중앙분리대 선상에 일정한 간격으로 비교적 낮게 세운 전주(1) 정상의 도자기애자(1')면에 송전선(2)(2')를 상하병렬로 가설하고 일반 승용차 또는 버스 등 차량의 운전석 쪽 천장(3)의 좌우 양측구멍(4)에 설치한 주관(5)에는 돌기(6)달린 내관(7)을 삽입하되 우측이 좌측보다 약간 높게 하고 그 내관(7)의 측벽에는 가늘고 긴 스프링(8)포올(pole)(9)의 한 쪽 기부(10)를 핀(11)으로 헐겁게 고정하고 그 선단의 L자형의 활접봉(12)이 송전선(2)(2')에 탄력적으로 접촉케하고 기부(10)의 선단구멍에 결부한 끈(13)의 하단은 내관(7)의 하단에 고정된 원판(14)의 중심공에 삽입되어서 고정하고, 내관(7) 하단에는 손잡이(16)를 고정하여서 된 것이다.Transmission lines (2) (2 ') are installed in vertical and parallel lines on the ceramic insulator (1') on the top of Jeonju (1), which is set relatively low at regular intervals on the line of the median of the road, and the driver's seat of a vehicle such as a general passenger car or bus. Insert the inner tube (7) with the projection (6) into the main pipe (5) installed in the left and right holes (4) of the ceiling (3), and the right side is slightly higher than the left side, and a long thin spring on the side wall of the inner tube (7) 8) Loosely fix one
도면중 미설명부호 21은 아래 송전선(2)과 위 송전선(2')의 간격유지용 절연체선을 표시한 것임.In the drawing,
이상과 같이 구성된 본 고안의 작용효과를 첨부한 도면에 의거 상세히 설명하면 다음과 같다.When described in detail based on the accompanying drawings the effect of the present invention configured as described above are as follows.
본 고안은 도로면의 중앙분리대선 상에 일정한 간격으로 비교적 낮게 전주(1)의 정상에 설치한 도자기애자(1')위에 상하병렬로 가설된 송전선(2)(2')은 버스차량 높이 정도로 낮게 가설하였기 때문에 차량이 일차선으로 진입하여 차량의 운전석쪽 천장(3)위의 좌우양측에 각각 설치된 가늘고 긴 스프링(8)포올(pole)(9)을 부도체로 된 손잡이(16)를 잡고 돌리면 높이를 미리 맞춰 놓은 스프링(8)포올(pole)(9) 선단의 L자형 활접봉(12)이 자동으로 송전선(2)(2')에 탄력적으로 접촉된다.The present invention is based on the ceramic insulator 1 'installed on the top of Jeonju 1 at regular intervals on the central separation line of the road surface. Since the hypothesis is low, the vehicle enters the primary lane and turns the elongated spring (8) pole (9), which is installed on the left and right sides of the vehicle's driver's seat ceiling (3), while holding the non-conductive handle (16). The L-
스프링(8) 포올(9)로 흐르는 전류는 주관(5)에 삽입된 내관(7)으로 분류하고, 내관(7)으로 흐르는 전류는 차량 동력으로서 도 6에 표시한 바와 같이 배선회로를 구성하면 고성능의 전기 모터(M)에 의하여 지하철과 같이 고속운행이 가능하고 또 주행하면서 배터리(B)에만 충전되므로 송전선(2)(2')시설이 없는 길로 진입할 경우에는 배터리 동력으로 운행이 가능하다. 따라서 도로변에 충전소를 설치할 필요가 없다.The current flowing through the
손잡이(16)를 잡고 그 내관(7)을 돌리면 도 4에 표시한 바와 같이 내관(7)의 상방돌기(6)가 주관(5) 상단에 형성된 홈(6')에 자동으로 박히므로 버튼(15)에서 손을 떼도 포올(9) 선단의 활접봉(12)은 송전선(2),(2')에서 이탈하지 않는 효과가 있다.Holding the
이와 같이 일차선에서 배터리에 충전이 완료되면 손잡이(16)를 위로 약간 밀어 올려서 돌기(6)를 홈(6')에서 이탈케 하여 돌리면 스프링(8) 포올(9) 선단의 활접봉(12)이 송전선(2),(2')에서 이탈하여 지붕 위쪽으로 나란히 이동하므로 다른 차선에서 안전하게 운행하다가 배터리 전력이 부족해지면 일차선(一次線)으로 이동하여 송전선(2),(2')으로부터 전력공급을 받아 운행하면서 배터리에 재충전한다.As such, when the battery is fully charged in the primary line, the
그리고 도 6에 표시한 전극계통 회로도에서 C는 컨트롤러(CONTROLLER), M은 전동기(ELECTRIC MOTOR), B는 배터리(BATTERY), LC는 로컬충전기(LOCAL CHARGER)를 표시한 것임.In the electrode system circuit diagram shown in FIG. 6, C denotes a controller, M denotes an electric motor, B denotes a battery, and LC denotes a LOCAL CHARGER.
이상과 같이 종래의 전력공급선은 가는 방향과 오는 방향의 도로 위에 따로 전선을 가설하여 전력을 받는 데 반해, 본 고안은 중앙분리대선 상에 상하병렬로 송전선을 설치하여 가고 오는 차량이 공통으로 전력공급을 받게 하였기 대문에 공사비가 종래의 50%정도로 크게 절감되는 효과가 있고 도로변에 충전소 설치가 필요없고 충전의 번거로움도 생략되고 또 차량운행비도 크게 절감되는 경제적 효과가 크고, 100% 친환경적이어서 실용성 및 파급효과가 높다.As mentioned above, the conventional power supply line receives electric power by laying wires separately on the road in the direction of the direction and the direction of the coming, whereas the present invention is common to supply power to vehicles coming and going in parallel with the transmission line installed on the central separation line. As the construction cost is greatly reduced to about 50%, it is not necessary to install a charging station on the roadside, eliminating the hassle of charging, and the economic effect is greatly reduced. The ripple effect is high.
