1 is a view showing the structure of a power supply rail module 100 according to an embodiment of the present invention.

The feed rail module 100 includes a feed line passage 110 for receiving a feed line extending along a road progress direction, a feed core 120 disposed below the feed line passage, and a concrete structure 130 containing a feed line passage and a feed core. The length 131 parallel to the road traveling direction of the power supply rail module 100, a width 132 perpendicular to the road traveling direction, and a height 133 in the vertical direction are displayed.

In order to install and install the power supply device by the power supply rail module 100, first, the road is dug to a certain depth, and then the plurality of power supply rail modules 100 are connected in series in the direction parallel to the road progression direction, and then on the excavated road. To place. Thereafter, the feeder is inserted into the feeder passage 110 in a direction parallel to the road progression direction and finally covered with asphalt. As the power feeding cores and feeders are protected by concrete structures without being directly loaded by roads, electric vehicles buried in the roads despite the deformation and breakage of the roads, which are often caused by driving, temperature and rainfall, etc. The power feeding device operates normally, and can stably supply electric power to the electric vehicle running on the road.

In addition, by making the concrete module 100 in this way, the installation and construction of the electric vehicle power supply device is very easy.

FIG. 2 is a diagram illustrating an embodiment of a cross section (front view) of a power feeding device installed at a lower portion of a road using a feed rail module 100 perpendicularly to a road traveling direction.

The feed line 10 is protected by an insulating tube 11 to prevent discharge to the outside, and is inserted to extend in the road progression direction to the feed line passage 110 on the feed core 120.

And a communication line passage 150 through which the communication line 30 for communication with the outside is provided. The common line 20 and the communication line 30 are also protected by the insulating tubes 21 and 31, respectively. Insulation pipes (11, 21, 31) can also be wrapped around the vinyl several times to enhance the waterproof function.

The insulated pipes 11, 21, 31 may be made of PVC, or a corrugated pipe may be used instead of the rigid PVC pipe. When inserting the cable into the insulated pipes (11, 21, 31), you can use the method of hanging down the pipe in a high building using gravity and then inserting the cable using the force falling by gravity. When inserted, the cable is not waterproof due to frictional insertion or damage to the pipe and cable surfaces.

On the other hand, this figure shows an embodiment in the case where the common line 20 is located in the center.

In this case, if only 5cm apart from the heat generated by the magnetic induction is not large. Road progress direction reinforcing bar 40 is to reduce the breakage of the pipe and to reduce the cracking, especially by the cut plane fault movement due to settlement. Alternatively, the reinforcing bar may be inserted in the lower part of the core in the left and right directions, but may be spaced apart from the reinforcing bar by several cm or more to prevent loop current caused by magnetic induction. When the installation of the power feeding device is completed is covered with an asphalt 200, the top.
