Description

비접촉 자기 유도 충전 방식의 전기자동차 집전모듈{POWER PICK UP MODULE FOR ON LINE ELECTRIC VEHICLE}Electric vehicle current collecting module with non-contact magnetic induction charging {POWER PICK UP MODULE FOR ON LINE ELECTRIC VEHICLE}

본 발명은 비접촉 자기 유도 충전 방식의 전기자동차와 관련된 것으로서, 더욱 상세하게는 지상에서 급전하는 방식에 효과적인 자기 유도 충전 방식의 전기자동차 집전용 모듈에 관한 것이다.The present invention relates to an electric vehicle of a non-contact magnetic induction charging method, and more particularly, to an electric vehicle current collector module of a magnetic induction charging method effective in the ground feeding method.

일반적으로, 비접촉 자기 유도 충전 방식 전기자동차는 충전된 전기 배터리로 움직이는 전기자동차(EV)와는 달리 주행 중 또는 정차 중에 무선의 전원공급장치로부터 전원을 공급받는다. In general, a non-contact magnetic induction charging type electric vehicle, unlike an electric vehicle (EV) moving with a charged electric battery receives power from a wireless power supply while driving or stopping.

이를 위해 도로 밑면에서 전원을 공급해주는 급전장치와 차량에서 전원을 받아들이는 집전판 부분이 구성되는데, 비접촉 자기 유도 충전 방식 전기 자동차(OLEV)는 주행 중에 전원공급이 가능하기 때문에 불필요한 배터리를 많이 싫고 다닐 필요가 없다. For this purpose, a power supply unit is provided at the bottom of the road and a current collector portion for receiving power from the vehicle.The non-contact magnetic induction electric vehicle (OLEV) can be supplied with power while driving, eliminating unnecessary battery. no need.

그러나, 이와 같이 도로 밑면에서 전원을 공급해주는 방식은 여러 가지 문제점을 안고 있다.However, this way of supplying power from the bottom of the road has a number of problems.

먼저, 비접촉 자기 유도 충전방식의 전기자동차를 위한 종래의 고압선 또는 급전선 매설 방식 도로 구조는 아스팔트 또는 시멘트 콘크리트를 사용하는 방식으로 요구 피로 하중의 불만족, 내균열성 부족에 따른 균열 위험, 내방수성 부족으로 인한 전력 누설 위험 등에 취약한 구조로 되어있다.First, the conventional high-voltage or feeder embedding road structure for the non-contact magnetic induction charging type electric vehicle uses asphalt or cement concrete. The structure is vulnerable to the risk of power leakage.

아스팔트 콘크리트 내에 급전선 및 기타 부대 시설을 매설할 경우 아스팔트 콘크리트의 강성이 부족하여 차량하중에 의한 변형이나 처짐 등이 발생할 경우 아스팔트 콘크리트 자체의 균열뿐만 아니라 급전선 보호관등에 균열을 유발할 수 있어 누전 등의 문제를 야기할 수 있다. In the case of embedding feeder and other auxiliary facilities in asphalt concrete, if there is insufficient rigidity of asphalt concrete and deformation or sag caused by vehicle load may cause not only cracking of asphalt concrete itself but also cracking of feeder line, etc. Can cause.

또한 시멘트 콘크리트내부에 급전선 등을 매설할 경우 시멘트 콘크리트 타설시 건조수축으로 인한 균열 및 대기온도 변화에 따른 시멘트 콘크리트의 수축팽창 등에 의한 균열이 유발된다. In addition, embedding feeder in cement concrete causes cracking due to dry shrinkage and shrinkage expansion of cement concrete due to changes in atmospheric temperature when cement concrete is placed.

이를 억제하기 위하여 시멘트 콘크리트를 일정한 간격으로 분할하여 타설할 경우 건조수축 등의 균열을 억제하는데에는 효과가 있으나 분리된 이음매에서 도로하부 구조의 불균등한 지지력에 의한 부등침하가 발생하여 급전선 보호관의 균열 등을 유발할 수 있다. In order to suppress this, when cement concrete is divided and placed at regular intervals, it is effective in suppressing cracks such as dry contraction. May cause.

더욱이 아스팔트 및 시멘트 콘크리트는 완벽한 방수가 불가능하기 때문에 고압의 급전선을 매설하는 재료로서는 부적합한 실정이다. In addition, asphalt and cement concrete is not suitable as a material for embedding a high-voltage feeder because it is not completely waterproof.

또한, 기존의 도로 매설형 급전 구조는 전력전송장치를 도로에 매설하여야 하므로 시공상 많은 비용 및 시간이 소요되며, 보수 및 교체에도 많은 비용 및 시간이 소요될 수밖에 없다.In addition, the existing road buried feed structure requires a large amount of cost and time for construction, because the power transmission device must be embedded in the road, it is inevitably expensive and time-consuming to repair and replace.

그리고, 우천 시 도로 하부로 스며드는 물에 대한 방수 문제를 고려하여 설 계하여야 하며, 집전판의 설치 위치가 차량 바닥면에 한정되므로 과속방지턱과의 충돌로 인한 집전판의 파손을 고려해야 하는 등 많은 설계상의 제약이 따르게 된다.In addition, it is necessary to design in consideration of the water-proof problem of water seeping into the lower part of the road during rainy weather. Since the installation position of the current collector plate is limited to the floor of the vehicle, many designs such as damage to the current collector plate due to collision with the speed bumps should be considered. Will be subject to restrictions.

그리고, 통행하는 차량하중으로 인한 도로 파손에 따른 급전장치의 파손을 방지하기 위한 많은 고려가 필요하다. 즉, 콘크리트가 타설이 된 급전레일의 지면 위부분에서 하중이 주기적으로 가해졌을 시 틈 부분에서부터 크랙이 발생하여 위험한 상황이 생길 수도 있으므로 이에 대한 대비가 요구된다. In addition, much consideration is needed to prevent damage to the power feeding device due to road damage caused by the traffic load. In other words, when a load is periodically applied on the ground of the feed rail on which concrete is poured, a crack may occur from the gap part and a dangerous situation may be generated.

또한, 급전레일이 콘크리트 타설등에 의해 지면 아래에 매설됨으로 인해 자기장의 형태로만 에너지를 흡수하는 집전 방식에서는 지면 매설로 인해 집전효율을 높이는 것이 쉽지 않다. In addition, since the feed rail is buried beneath the ground by concrete pouring, it is not easy to increase the current collecting efficiency due to the grounding in the current collecting method that absorbs energy only in the form of a magnetic field.

본 발명은 상기한 제반 문제점을 해결하기 위하여 안출된 것으로서, 급전선을 지면에 매설에 매설하는 방식이 아닌 지상에 가설하는 방식의 급전시스템에 적합한 비접촉 자기 유도 충전 방식의 전기자동차 집전모듈을 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems, and provides a non-contact magnetic induction charging type electric vehicle current collecting module suitable for a power supply system of the method of laying the feeder on the ground rather than embedding the feeder on the ground. There is a purpose.

즉, 기존의 과속방지턱과의 충돌로 인한 집전판의 파손을 해소할 수 있고, 집전효율을 효과적으로 높일 수 있는 비접촉 자기 유도 충전 방식의 전기자동차 집전용 모듈을 제공하는데 그 목적이 있다.That is, the purpose of the present invention is to provide a non-contact magnetic induction charging type electric vehicle current collecting module that can solve the damage of the current collector plate due to the collision with the existing speed bump, and effectively increase the current collecting efficiency.

상기한 바와 같은 목적을 달성하기 위해 본 발명은, 차량 측에 고정되는 메인프레임과, 상기 메인프레임 일측에 회전가능하게 설치되는 메인 베어링과, 상기 메인 베어링에 결합되어 회동하는 메인 아암과, 상기 메인 아암을 감싸면서 메인 베어링에 결합되는 회전 암통과, 상기 메인프레임 타측에 회전가능하게 각각 설치되는 제1보조 베어링 및 제2보조 베어링과, 상기 제1보조 베어링과 회전 암통 외주면 일측을 연결하는 제1보조축과, 상기 제2보조 베어링과 회전 암통 외주면 타측을 연결하는 제2보조축과, 상기 메인 아암의 선단부에 결합되어 전력선으로부터 에너지를 받아들이는 집전판을 포함하여 구성되는 비접촉 자기 유도 충전 방식의 전기자동차 집전모듈이 제공된다.In order to achieve the above object, the present invention, the main frame is fixed to the vehicle side, the main bearing is rotatably installed on one side of the main frame, the main arm coupled to the main bearing to rotate, and the main A first arm connecting the first arm bearing and the second arm bearing rotatably installed on the other side of the main frame, the first arm bearing and the second arm bearing outer circumferential surface of the main arm, respectively; A non-contact magnetic induction charging method comprising an auxiliary shaft, a second auxiliary shaft connecting the second auxiliary bearing and the other side of the rotary arm outer circumferential surface, and a current collector coupled to the distal end of the main arm to receive energy from a power line. An electric vehicle current collecting module is provided.

이때, 상기 회전 암통 선단부에는 메인 아암이 처짐없이 회전 암통의 중심부 에 위치하도록 상기 메인 아암을 지지하는 지지아암이 설치되는 것을 특징으로 한다.At this time, the support arm for supporting the main arm is installed at the tip of the rotary arm barrel is located in the center of the rotary arm without sagging.

한편, 전술한 구성에 있어서, 상기 집전판 일측에는 전력선과 집전판 간의 상대적인 위치를 실시간으로 계산할 수 있도록 자기장을 측정하는 다수의 자기장 센서가 장착됨을 특징으로 한다.On the other hand, in the above-described configuration, one side of the current collector plate is characterized in that a plurality of magnetic field sensors for measuring the magnetic field so as to calculate the relative position between the power line and the current collector plate in real time.

본 발명에 따르면, 전력 공급 방법을 전력선 매설 방식이 아닌 지상 급전 구조로 개선함에 따라 이에 대응하는 효과적인 집전용 모듈을 제공할 수 있게 된다.According to the present invention, it is possible to provide an effective current collecting module corresponding to this, as the power supply method is improved to the ground feeding structure instead of the power line embedding method.

즉, 집전판을 차량 하부에 장착할 수밖에 없었던 기존 매설 방식과는 달리 집전모듈을 차량 상부로 배치함으로써 과속방지턱등 도로 구조물과의 충돌로 인한 집전판의 파손을 미연에 방지할 수 있고, 집전판을 전력선에 보다 근접시킬 수 있어 집전효율을 효과적으로 높일 수 있게 된다.In other words, unlike the existing buried method of mounting the current collector plate on the lower part of the vehicle, the current collector module is disposed on the upper part of the vehicle to prevent damage to the current collector plate due to collision with road structures such as speed bumps. It can be closer to the power line can effectively increase the current collector efficiency.

A first auxiliary bearing 7 and a second auxiliary bearing 9 rotatably installed on the first auxiliary shaft 3 and a first auxiliary shaft 3 connecting one side of the outer circumferential surface of the first auxiliary bearing 7 and the rotary arm barrel 1, respectively. And a second auxiliary shaft 4 connecting the second auxiliary bearing 9 and the other side of the outer circumferential surface of the rotary arm cylinder 1, and a current collector plate coupled to the distal end of the main arm 2 to receive energy from the power line ( 5) is configured to include.

이때, 상기 회전 암통(1) 선단부에는 메인 아암(2)이 처짐없이 회전 암통(1)의 중심부에 위치하도록 상기 메인 아암(2)을 지지하는 지지아암(10)이 설치된다.At this time, the support arm 10 supporting the main arm 2 is provided at the tip of the rotary arm 1 so that the main arm 2 is located at the center of the rotary arm 1 without sagging.

그리고, 상기 집전판(5) 일측에는 전력선과 집전판(5) 간의 상대적인 위치를 실시간으로 계산할 수 있도록 자기장을 측정하는 다수의 자기장센서(6)가 장착된다.

그리고, 상기 메인 베어링(8)과, 제1보조 베어링(7) 및 제2보조 베어링(9)은 볼형태로서 메인프레임(M/F) 상에서 상하 및 좌우로 회전할 수 있도록 설치된다.In addition, the main bearing 8, the first auxiliary bearing 7 and the second auxiliary bearing 9 are installed in a ball shape so as to rotate vertically and horizontally on the main frame M / F.

한편, 도 4를 참조하면, 본 발명의 집전모듈에 대응하는 급전레일 모듈은, 지상에 가설되어 에너지를 공급하는 급전선(11)과, 상기 급전선(11)을 따라 연결되며 상기 급전선(11)을 지지하는 절연지지체(12)와, 상기 절연지지체(12)를 따라 연결되어 상기 절연지지체(12)를 지지함과 더불어 접지 역할을 겸하는 접지선(13)과, 상기 급전선(11)과 절연지지체(12) 및 접지선(13)을 이격된 상태에서 감싸게 되는 보호커버(14)를 포함하여 구성된다.On the other hand, referring to Figure 4, the feed rail module corresponding to the current collecting module of the present invention, the feed line 11 is installed on the ground to supply energy and connected along the feed line 11 and the feed line 11 Insulating support 12 to support, the ground wire 13 is connected along the insulating support 12 to support the insulating support 12 and serves as a ground, the feed line 11 and the insulating support 12 And a protective cover 14 to surround the ground wire 13 in a spaced apart state.

이와 같이 구성된 본 발명의 집전 모듈의 작용은 다음과 같다.The action of the current collecting module of the present invention configured as described above is as follows.

온라인 버스의 천정의 한쪽 가장자리 근처에 집전모듈이 설치된다. 집전모듈의 메인 아암(2) 및 회전 암통(1) 등은 메인프레임(M/F)을 축으로 회전이 가능하며 집전을 하지 않을 때에는 차량의 위쪽 혹은 그 부근으로 움직일 수 있다.A current collecting module is installed near one edge of the ceiling of the online bus. The main arm 2 and the rotary arm 1 of the current collecting module may rotate about the main frame M / F, and may move toward or near the vehicle when no current collecting is performed.

상기 메인프레임(M/F)과 연결되어 있는 메인 아암(2)은 커다란 회전 암통(1)안에 감싸져 있으며, 상기 회전 암통(1)에는 집전판(5)의 위치를 변경할 수 있도록 제1보조축(3) 및 제2보조축(4)이 사다리꼴 형태의 링크 구조를 이루도록 연결된다. The main arm 2 connected to the main frame M / F is enclosed in a large rotary arm 1, and the rotary arm 1 is provided with a first auxiliary to change the position of the current collector plate 5. The shaft 3 and the second auxiliary shaft 4 are connected to form a trapezoidal link structure.

상기 메인 아암(2)의 전체적인 움직임은 메인프레임(M/F)에 설치되며 상기 메인 아암(2)이 결합된 메인 베어링(8)이 담당하고 집전판(5)이 항상 노출된 급전선(11)과 평행을 유지할 수 있도록 하기 위해 제1보조축(3)과 제2보조축(4)이 각각 제1보조 베어링(7)과 제2보조 베어링(9)에 연결되어 있다. The overall movement of the main arm 2 is installed on the main frame (M / F), the main bearing (8) coupled to the main arm (2) is in charge and the current collector plate 5 is always exposed to the feed line (11) The first auxiliary shaft 3 and the second auxiliary shaft 4 are connected to the first auxiliary bearing 7 and the second auxiliary bearing 9, respectively, in order to maintain parallel to the first auxiliary shaft 3 and the second auxiliary shaft 4, respectively.

따라서, 차량의 주행 중 발생하는 움직임으로부터 메인프레임(M/F)과 같이 연결된 각각의 베어링들이 조금씩 회전이 발생하더라도 집전판(5)의 링크는 항상 평행을 유지할 수 있다. Therefore, even if each of the bearings connected to the main frame (M / F) is rotated little by little from the movement occurring during the driving of the vehicle, the link of the collector plate 5 can always be kept parallel.

그리고, 상기 제1보조축(3)과 제2보조축(4)이 회전 암통(1)에 연결되어 있어 교차로를 지나기 위해 집전판(5)이 급전선(11)으로부터 떨어지더라도 회전 암통(1) 및 메인 아암(2)의 처짐이 방지됨으로써, 교차로를 지나서 새로 나타난 급전선(11)과 차량의 집전판(5)과의 연결이 자연스럽게 이루어지게 된다. Further, the first auxiliary shaft 3 and the second auxiliary shaft 4 are connected to the rotary arm 1 so that the rotary arm 1 even if the current collector plate 5 is separated from the feed line 11 so as to pass through the intersection. And since the deflection of the main arm 2 is prevented, the connection between the newly-feeding power line 11 and the current collector plate 5 of the vehicle is naturally made through the intersection.

한편, 집전판(5)의 앞쪽 혹은 주변에 장착되는 다수의 자기장 센서(6)를 이 용하여 자기장을 측정하고 삼각측정법을 이용하여 전력선과 집전판(5) 간의 상대적인 위치를 실시간으로 계산할 수 있다. 그리고 계산된 결과를 이용하여 상기 집전판(5)이 노출된 급전선(11)을 완벽하게 추종할 수 있도록 실시간으로 제어할 수 있다.Meanwhile, the magnetic field may be measured using a plurality of magnetic field sensors 6 mounted in front of or around the current collector plate 5, and the relative position between the power line and the current collector plate 5 may be calculated in real time using triangulation. In addition, using the calculated result, the current collector plate 5 may be controlled in real time to completely follow the exposed feeder line 11.

그리고, 교차로 부분에서는 급전을 받지 않고 버스 안에 충전된 배터리를 이용하여 이동하게 되는데, 차량의 집전판(5)은 급전선(11)과 연결시에 위치 추종을 하여 서로 연결할 수 있도록 제어하고 그 반대로 집전판(5)이 떨어지는 시점에서 자동으로 단락이 되도록 제어한다.
