이와 같이 구성된 본 발명의 작용은 다음과 같다.The operation of the present invention configured as described above is as follows.

먼저, 본 발명의 급전레일 모듈을 구성하는 보호커버(1)는 급전라인(5)의 길이방향을 따라 연속적으로 상부 및 측면을 감싸도록 형성되어 도로 위로부터 가해지는 충격과 하중을 흡수하여 충격과 하중에 의한 급전레일의 손상을 방지한다.First, the protective cover 1 constituting the feed rail module of the present invention is formed to surround the top and side continuously along the longitudinal direction of the feed line (5) to absorb the impact and load applied from the road to the impact and Prevents damage to the feed rail by the load.

그리고, 상기 보호커버(1)는 급전라인(5)의 길이방향을 따라 연속적으로 상부 및 측면을 감싸도록 형성되어 빗물등의 수분이 위쪽이나 측면에서 급전라인(5) 으로 유입되는 현상을 차단하게 된다.In addition, the protective cover 1 is formed to continuously wrap the upper and side in the longitudinal direction of the feed line 5 to block the phenomenon that water such as rainwater flows into the feed line 5 from the top or side. do.

또한, 상기 스페이서(3)는 충분한 강성을 갖는 FRP(강화플라스틱) 등의 절연체로 이루어져, 만약 빗물이 아래로 스며들 경우에 스페이서(3)에 의해 절연덕트(2)와 자속누설방지부재(4) 사이의 공간을 통해 빗물이 흘러나가도록 함으로써 급전라인(5)측으로는 빗물이 유입되지 않도록 막아주는 역할을 하게 된다.In addition, the spacer 3 is made of an insulator such as FRP (reinforced plastic) having sufficient rigidity, and if the rainwater penetrates down, the insulation duct 2 and the magnetic flux leakage preventing member 4 are separated by the spacer 3. By rainwater flows through the space between) serves to prevent the rainwater flows into the feed line (5) side.

그리고, 상기 자속누설방지부재(4)는 급전라인(5) 좌우측 및 아래쪽으로의 자속누설을 차단하는 자성체로서 페라이트(ferrite)재질의 구조체로 이루어짐이 바람직하며, 구조적으로 급전라인(5) 아래쪽에서 급전라인(5)을 가로질러 설치됨과 아울러 급전라인(5) 좌우측으로 상향 돌출되는 형태를 이루어 급전라인(5) 좌우측 및 아래쪽으로의 자속누설을 차단하게 된다.In addition, the magnetic flux leakage preventing member 4 is a magnetic material that blocks magnetic flux leakage to the left and right sides and the lower side of the power supply line 5, and is preferably made of a ferrite material structure, and structurally below the power supply line 5.

이에 따라, 자기장의 방향이 급전라인(5) 상부방향으로 집중됨으로써 에너지 효율을 상승시킨다. Accordingly, the direction of the magnetic field is concentrated in the upper direction of the feed line 5 to increase the energy efficiency.

그리고, 상기 페라이트구조체는 충격 및 하중 등으로 인해 균열이 일어나더라도 자속의 누설을 차단하여 전기자동차의 전력집전장치(미도시) 쪽으로 자기장이 집중될 수 있도록 역할하게 된다.In addition, the ferrite structure serves to block the leakage of magnetic flux even if a crack occurs due to impact and load so that the magnetic field can be concentrated toward the electric power collector (not shown) of the electric vehicle.

그리고, 상기 급전레일 모듈은 좌우측에 각각 급전라인(5)이 설치되는 듀얼(dual) 타입이어서, 급전라인(5)이 하나만 배치된 경우에 비해 더욱 많은 에너지를 전력집전장치 쪽으로 공급할 수 있게 된다. In addition, the power supply rail module is a dual type in which power supply lines 5 are installed at left and right sides, respectively, so that more energy can be supplied to the power collector than when only one power supply line 5 is disposed.

한편, 상기한 본 발명의 급전레일 모듈을 적용한 도로 구조 및 시공에 대해 설명하면 다음과 같다.On the other hand, the road structure and construction to which the feed rail module of the present invention described above is described as follows.

본 발명의 비접촉 자기 유도 충전 방식의 전기자동차 급전레일 모듈을 적용한 도로 시공 방법에 따르면, 급전레일모듈 시공용 터파기를 수행하는 단계(도 4a 참조)와, 터파기한 바닥면에 기초면 콘크리트(6)를 타설하는 단계(도 4b참조)와, 급전레일모듈을 설치하는 단계와, 아스팔트 등 포장재(8)를 이용하여 급전레일모듈을 봉지(encapsulating)하는 단계를 포함한다. According to the road construction method applying the electric vehicle feed rail module of the non-contact magnetic induction charging method of the present invention, the step of performing the feed rail module construction trench (see Fig. 4a), and the base surface concrete (6) It includes the step (see Figure 4b), the step of installing the feed rail module, and encapsulating the feed rail module using the packaging material (8), such as asphalt.

이때, 급전레일모듈 설치는, 자속의 누설 방지를 위한 페라이트구조체가 매설된 콘크리트구조체(7)를 기초면 콘크리트(6) 위로 설치하는 단계(도 4c 참조)와, 상기 페라이트구조체 위로 스페이서(3)를 설치하는 단계(도 4d 참조)와, 상기 스페이서(3) 위로 급전라인(5)을 가설하는 단계와, 상기 급전라인(5) 외측에 보호커버(1)를 설치하는 단계를 포함한다. At this time, the power supply rail module installation, the step of installing a concrete structure (7) embedded with a ferrite structure for preventing leakage of magnetic flux on the base surface concrete (see Fig. 4c), and the spacer 3 over the ferrite structure It includes the step (see FIG. 4D), the step of installing the power supply line 5 over the spacer 3, the step of installing a protective cover (1) outside the power supply line (5).

상기 페라이트구조체가 매설되는 콘크리트구조체(7)는 현장이 아닌 공장에서 프리캐스트(Precast)됨이 바람직하다.Concrete structure 7 in which the ferrite structure is embedded is preferably precast (precast) at the factory, not the site.

이와 같은 도로 시공 과정 및 그 작용에 대해 보다 구체적으로 살펴보면 다음과 같다.Looking at the road construction process and its action in more detail as follows.

도 2 및 도 3을 참조하면, 본 발명의 실시 예는 비접촉 자기 유도 충전 방식의 전기자동차용 급전레일모듈이 일반도로에서 충격과 하중에 대해 안전성을 가지기 위해 먼저 급전레일모듈을 설치하기 전 도로를 파낸 상태는 표면이 불균일하여 모듈을 설치할 경우 충격과 하중에 의해 변형이 생기게 되므로, 이를 방지하기 위해 모듈을 매설하기 전에 시멘트로 기초 바닥면을 타설함으로써 급전레일모듈의 하중에 대한 안전성을 확보한다.2 and 3, an embodiment of the present invention is a non-contact magnetic induction charging method for the electric vehicle feed rail module in order to have a safety against shock and load in the general road first before installing the feed rail module In the dug state, the surface is uneven, so when the module is installed, deformation occurs due to impact and load. To prevent this, the foundation floor is casted with cement before embedding the module to secure the safety of the load of the feeding rail module.

또한, 도로표면으로부터 직접적으로 받는 하중에 대해서도 급전레일의 안전성을 확보하여야 함으로 "

Figure 112009063505912-pat00003
" 형태의 보호커버(1)를 설치하여 안전성에 대한 신뢰성을 더욱 향상시킨다.In addition, the safety of the feed rail should be ensured against loads directly received from the road surface.
Figure 112009063505912-pat00003
By installing the protective cover (1) of the form further improves the reliability for safety.

한편, 본 발명 급전레일모듈의 방수 문제를 해결하기 위한 내구설계가 필요하다. 이를 극복하기 위해 PVC등의 절연재로 된 절연덕트(2) 내부에 급전라인(5)을 매설한다. 이는 1차적으로 물과 급전라인(5)이 접촉하는 것을 막아주게 된다. On the other hand, there is a need for a durable design to solve the waterproof problem of the feed rail module of the present invention. In order to overcome this, the power supply line 5 is embedded in an insulation duct 2 made of an insulation material such as PVC. This primarily prevents the water and the feed line 5 from contacting.

또한 충격과 하중을 흡수하는 "

Figure 112009063505912-pat00004
"형태의 보호커버(1)가 도로 내부로 흡수되는 물을 2차적으로 급전라인(5)으로 유입되지 않도록 차단한다.Also absorb shock and load "
Figure 112009063505912-pat00004
The protective cover 1 of the "shape" prevents water absorbed into the road from being introduced into the feed line 5.

그리고, 급전라인(5)쪽으로 물이 차올라오는 경우 또한 고려하여 스페이서(3)를 급전라인(5) 아래쪽에 설치함으로써 3차적으로 물과의 접촉을 차단하여 방수 문제를 완전히 해결할 수 있도록 한다.In addition, when the water rises toward the power supply line 5, the spacer 3 is disposed below the power supply line 5 to allow the third contact to be blocked in order to completely solve the waterproof problem.

한편, 급전라인(5)에서 발생하는 자기장은 일반적인 자기장 형태를 가지게 되는데 이는 에너지 효율이 낮다는 문제점을 야기한다. On the other hand, the magnetic field generated in the feed line 5 has a general magnetic field form, which causes a problem of low energy efficiency.

본 발명에서는 이러한 문제점을 극복하기 위한 방안으로 에너지 효율을 상승시키기 위하여 급전라인(5) 주변에 자속누설방지부재(4)인 페라이트 구조체를 설치함으로써, 자기장의 방향을 조절해 급전라인(5)에서 발생하는 자기장의 방향을 에너지를 받아들이는 차량의 전력집전장치 방향으로 치우치게 하여 에너지 효율을 70%까지 상승시킬 수 있게 된다. In the present invention, in order to overcome this problem by installing a ferrite structure, the magnetic flux leakage preventing member (4) around the feed line (5) to increase the energy efficiency, by adjusting the direction of the magnetic field in the feed line (5) The direction of the generated magnetic field is biased toward the power collector of the vehicle that receives the energy, thereby increasing the energy efficiency by 70%.
