일반적으로 비접촉 자기 유도 방식의 전기자동차의 집전장치는 급전도로에서 발생하는 자기장의 힘을 전기에너지로 변환시키는 트랜지스터의 원리가 적용된다. 이 때, 급전도로에 흐르는 고압전류가 발생시키는 자기장이 오른나사의 법칙에 의해 흐르는데, 차량의 하부에 설치된 집전장치가 급전도로와 수평한 평면형상이기 때문에 집전장치와 급전도로 사이의 공극에서 전자파 및 자기장이 외부로 누출되는 현상이 발생하게 된다.

이하, 첨부된 도면을 참조하여 비접촉 자기 유도 충전 방식의 전기자동차용 자기장 차폐장치 및 그 작동방법에 대한 바람직한 실시예를 상세히 설명한다. Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the magnetic field shielding device for an electric vehicle of the non-contact magnetic induction charging method and its operation method.

먼저, 도 1 내지 도 3을 참조하여 본 발명에 따른 비접촉 자기 유도 충전 방식의 전기자동차용 자기장 차폐장치의 구성에 대해 설명한다. First, a configuration of a magnetic field shielding device for an electric vehicle of a non-contact magnetic induction charging method according to the present invention will be described with reference to FIGS. 1 to 3.

도 1을 참조하면, 급전도로(1)에 페라이트코어(2) 및 이 페라이트코어(2)에 권선된 1차 코일(3)로 이루어진 급전장치가 매설되고, 전기자동차의 차체 하부에 유기 전력을 생성하는 집전장치(5)가 설치된다. 상기 집전장치(5)는 급전도로(1)와 일정 간격을 유지하면서 상기 급전장치에 의해 생성된 자기장에 의해 유기 전력을 생성하여 차량의 모터(미도시) 또는 축전지(미도시)에 전력을 공급한다. 도면에 도시하지는 않았으나, 상기 집전장치(5)는 편평한 판상의 페라이트코어에 2차 코일이 감겨진 구조로 이루어진다. Referring to FIG. 1, a power feeding device including a ferrite core 2 and a primary coil 3 wound around the ferrite core 2 is embedded in a feed road 1, and organic power is applied to a lower portion of a vehicle body of an electric vehicle. The current collector 5 to be generated is installed. The current collector 5 generates organic power by a magnetic field generated by the power supply device while maintaining a predetermined distance from the power supply road 1 to supply power to a motor (not shown) or a storage battery (not shown) of the vehicle. do. Although not shown in the drawing, the current collector 5 has a structure in which a secondary coil is wound around a flat plate-like ferrite core.

그리고, 도 1 및 도 2에 도시된 것과 같이, 상기 전기자동차의 양측면 차체 프레임(4)에 공압 또는 유압에 의해 상하 방향으로 수직운동하는 피스톤(21)을 구비한 액츄에이터(20)가 설치되고, 이 액츄에이터(20)의 피스톤(21)에 상기 집전장치(5)의 양측면 외측부를 차폐하는 차폐부재(10)가 결합된다. 따라서, 상기 차폐부 재(10)는 액츄에이터(20)의 피스톤(21)과 함께 수직 이동하여, 차가 정지하여 집전장치에 충전이 이루어질 때 액츄에이터(20)의 작용에 의해 차량의 양측면 하측으로 이동하여 집전장치(5)와 급전장치 간에 발생하는 전자파 및 자기장이 외부로 누출되는 것을 방지하고, 충전이 이루어지는 않는 주행시에는 상측으로 이동하여 외부 물체와의 충돌 또는 간섭을 방지한다. 1 and 2, an actuator 20 having a piston 21 vertically moved upward and downward by pneumatic or hydraulic pressure is installed on both side body frames 4 of the electric vehicle. The piston 21 of the actuator 20 is coupled to the shield member 10 for shielding the outer side portions of both sides of the current collector (5). Accordingly, the shield member 10 moves vertically together with the piston 21 of the actuator 20, and moves downwards on both sides of the vehicle by the action of the actuator 20 when the vehicle is stopped and the charging is performed on the current collector. The electromagnetic wave and the magnetic field generated between the current collector 5 and the power feeding device are prevented from leaking to the outside, and when the vehicle is not charged, it moves upward to prevent collision or interference with external objects.

상기 액츄에이터(20)는 전기자동차의 컨트롤러(미도시)에 연결되며, 상기 컨트롤러(미도시)는 전기자동차의 도어(미도시)의 개폐 작동과 연동하여 상기 액츄에이터(20)에 공압 또는 유압을 인가한다. The actuator 20 is connected to a controller (not shown) of the electric vehicle, and the controller (not shown) applies pneumatic or hydraulic pressure to the actuator 20 in conjunction with the opening and closing operation of the door (not shown) of the electric vehicle. do.

상기 차폐부재(10)는 도 3에 도시된 것처럼, 자기장 차폐 기능을 갖는 복수개(이 실시예에서 3개)의 얇은 금속판재로 된 차폐플레이트(11)들이 상호 이격되어 적층된 구조로 이루어진다. 여기서, 상기 차폐플레이트(11)들은 상하단부가 각각 직각으로 밴딩된 'ㄷ'자형의 금속 판재로 이루어져, 볼트 또는 너트와 같은 체결부재에 의해 상호 결합된다. 상기와 같이 차폐부재(10)가 복수개의 금속 플레이트로 이루어지면, 하나의 금속판재를 두껍게 제작하여 차폐부재를 구성할 때보다 하중이 작아지기 때문에 액츄에이터(20)의 용량이 작은 것을 사용할 수 있으며, 차량의 전기소모량을 저감시킬 수 있을 뿐만 아니라, 전기장 및 자기장 차폐효과도 더욱 향상되는 이점을 얻을 수 있다. As shown in FIG. 3, the shielding member 10 has a structure in which shielding plates 11 made of a plurality of thin metal plates (three in this embodiment) having a magnetic field shielding function are stacked apart from each other. Here, the shielding plate 11 is made of a metal plate of the '' 'upper and lower ends bent at right angles, respectively, are coupled to each other by a fastening member such as a bolt or nut. When the shielding member 10 is made of a plurality of metal plates as described above, since the load is smaller than when the shielding member is manufactured by making one metal plate thick, the actuator 20 may have a smaller capacity. In addition to reducing the amount of electricity consumed by the vehicle, the electric and magnetic field shielding effects can be further improved.

그리고, 상기 차폐부재(10)의 각 차폐플레이트(11) 사이에 차폐플레이트(11)의 강도를 보강하기 위한 보강재(40)가 설치되는 것이 바람직하다. 이 실시예에서 상기 보강재(40)는 상기 차폐플레이트(11)들과 마찬가지로 'ㄷ'자형으로 밴딩된 금 속판재로 이루어지나, 이에 한정하지 않으며 다양한 형태로 이루어질 수 있다. In addition, it is preferable that a reinforcing material 40 for reinforcing the strength of the shielding plate 11 is provided between the shielding plates 11 of the shielding member 10. In this embodiment, the reinforcing material 40 is made of a metal plate bent in the '' 'like the shielding plate 11, but is not limited thereto and may be formed in various forms.

또한, 상기 차폐부재(10)의 하단부에는 차폐부재(10)가 노면 또는 노면 상의 물체에 부딪혀 직접적인 충격을 받지 않도록 하여 주는 완충용 댐퍼(30)가 장착된다. 상기 완충용 댐퍼(30)는 외부의 물체와 충돌했을 때 순간적으로 변형되면서 충격을 흡수할 수 있는 고무 등의 수지재로 이루어질 수 있지만, 이와 다르게 'U'자형으로 밴딩된 금속판재에 고무 등의 유연한 수지재가 덮힌 구조로 이루어질 수도 있다. In addition, the lower end of the shielding member 10 is equipped with a damping damper 30 to prevent the shielding member 10 from hitting the road surface or an object on the road surface to be directly impacted. The damper damper 30 may be made of a resin material such as rubber that can absorb a shock while being instantaneously deformed when it collides with an external object. It may be made of a structure covered with a flexible resin material.

상기 차폐부재(10)는 차량의 전륜(6)과 후륜(7)의 외측에 이격되게 설치되되, 전륜(6)과 후륜(7)의 방향 전환시 전륜(6)과 후륜(7)이 닿지 않을 정도의 충분한 거리를 유지하는 것이 바람직하다. The shielding member 10 is installed on the outside of the front wheel 6 and the rear wheel 7 of the vehicle, the front wheel 6 and the rear wheel 7 does not touch when the direction of the front wheel 6 and the rear wheel 7 is switched. It is desirable to keep enough distance.

그리고, 전자파 및 자기장 차폐 효과를 더욱 높이기 위하여 상기 차폐부재(10)의 전단부와 후단부는 차량으로 내측으로 절곡되게 형성되는 것이 바람직하다. In addition, the front end and the rear end of the shield member 10 is preferably formed to be bent inward to the vehicle in order to further enhance the electromagnetic and magnetic field shielding effect.

다음으로, 도 4와 도 5a 및 도 5b를 참조하여, 상술한 바와 같이 구성된 비접촉 자기 유도 충전 방식의 전기자동차의 차폐장치의 작동방법의 일 실시예에 대해 설명한다. Next, with reference to FIGS. 4, 5A and 5B, an embodiment of a method of operating a shielding device of an electric vehicle of a non-contact magnetic induction charging type configured as described above will be described.

차량의 운행 중 상기 액츄에이터(20)(도 2참조)를 구동시키는 컨트롤러(미도시)는 차량의 도어(미도시)의 개폐를 실시간으로 감지한다(단계 S1). A controller (not shown) for driving the actuator 20 (see FIG. 2) while the vehicle is running detects the opening / closing of the door (not shown) of the vehicle in real time (step S1).

차량이 급전장치가 설치된 정류장 또는 충전소에 정지하고, 승객을 탑승 또는 하차시키기 위하여 도어를 개방하면(단계 S2), 컨트롤러(미도시)가 이 도어 개 방을 감지하여 액츄에이터(20)(도 2참조)에 공압 또는 유압을 인가하여 도 5a에 도시한 것과 같이 차폐부재(10)를 차량의 양측면 하부로 하강시켜 집전장치(5)와 급전장치 간에 발생하는 자기장 및 전자파를 차폐시킨다(단계 S3). When the vehicle stops at the stop or charging station where the power supply is installed, and the door is opened to board or unload the passenger (step S2), the controller (not shown) detects the opening of the door and the actuator 20 (see Fig. 2). ) By applying pneumatic or hydraulic pressure to lower the shielding member 10 below both sides of the vehicle as shown in FIG. 5A to shield magnetic fields and electromagnetic waves generated between the current collector 5 and the power feeding device (step S3).

집전장치(5)의 충전이 이루어는 도중 또는 충전이 모두 완료되고, 차량의 도어가 폐쇄되고(단계 S4), 브레이크 작동 신호가 오프되면(단계 S5), 컨트롤러(미도시)는 차량이 주중인 것으로 판단하여 액츄에이터(20)를 작동시켜 도 5b에 도시된 것과 같이 차폐부재(10)를 다시 상승시킨다(단계 S6). When the current collector 5 is being charged or when the charging is completed, the door of the vehicle is closed (step S4), and the brake operation signal is turned off (step S5), the controller (not shown) indicates that the vehicle is in the main state. It is determined that the actuator 20 is operated to raise the shielding member 10 again as shown in FIG. 5B (step S6).

한편, 전술한 실시예에서는 차폐부재(10)를 상하로 승강시키는 구동수단으로서 유압 또는 공압에 의해 동작하는 액츄에이터(20)가 적용되었지만, 이와 다른 다양한 공지의 선형운동시스템을 이용하여 차량의 주행 속도에 따라 차폐부재(10)를 승강운동시킬 수 있을 것이다. Meanwhile, in the above-described embodiment, the actuator 20 operated by hydraulic pressure or pneumatic pressure is applied as a driving means for elevating the shield member 10 up and down, but the traveling speed of the vehicle using various other known linear motion systems. According to the shield member 10 will be able to move up and down.

또한, 전술한 실시예에서는 차량이 정지하고, 도어가 개방되면 바로 자동으로 차폐부재(10)가 하강하였으나, 도 6에 다른 실시예로 나타낸 것과 같이 차량이 정지하고, 도어가 개방된 후(단계 S2), 충전이 시작되는 것으로 감지되면(S2-1), 컨트롤러(미도시)가 충전이 시작되는 것을 감지하였을 때 차폐부재(10)를 하강시킬 수도 있을 것이다. In addition, in the above-described embodiment, the vehicle is stopped and the shield member 10 is automatically lowered as soon as the door is opened, but as shown in another embodiment in FIG. 6, after the vehicle is stopped and the door is opened (step) S2) If it is detected that the charging is started (S2-1), the controller (not shown) may lower the shield member 10 when the controller detects that charging is started.

상술한 바와 같은 본 발명에 따르면, 승객의 탑승 및 하차를 위해 도어가 개방되고 집전장치의 충전이 이루어질 때 컨트롤러가 구동수단을 작동시켜 차폐부재(10)를 하강시킴으로써 전자파 및 자기장을 차폐시키고, 자기장 누출에 따른 집전 효율 저하를 방지함과 동시에 전자파에 의해 차량의 외부에서 대기하고 있는 승 객에 미치는 악영향을 최소화할 수 있다. 또한, 도어가 폐쇄되고 차량이 주행하는 것으로 감지될 때에는 차폐부재(10)가 액츄에이터(20)의 작용에 의해 자동으로 상승하여 노면 또는 노면 상의 물체와의 충돌이 방지되므로 주행중 안전성을 향상시킬 수 있는 이점이 있다. According to the present invention as described above, when the door is opened for passengers boarding and getting off and the charging of the current collector is made, the controller operates the driving means to lower the shielding member 10 to shield the electromagnetic wave and magnetic field, It is possible to prevent the deterioration of current collection efficiency due to leakage and to minimize the adverse effect on passengers waiting outside of the vehicle by electromagnetic waves. In addition, when the door is closed and the vehicle is detected to be traveling, the shield member 10 is automatically raised by the action of the actuator 20 to prevent collision with the road surface or the object on the road surface, thereby improving safety while driving. There is an advantage.
