May include absences. Additionally, the lifting means may include a motor that rotates the roller by receiving a signal from the control device 2.

The elevating means (not shown) is explained as an example, and of course, various configurations can replace the roller and string member as long as they can elevate the plate member 812.

The transport means 81 may include a hinge 813 that couples the plate member 812 and the enclosure 80 so that the hinge rotates.

The hinge 813 can couple the enclosure 80 and the plate member 812 so that they rotate around the first direction as the central axis.

Additionally, the transportation means 81 may include an external wheel 814 connected to (equipped with) the lower front of the enclosure 80.

The arrangement structure of each component of the automatic arrangement means 8 will be described based on [C] and [D] in FIG. 11.

Although not shown, the transport means 81 includes a bottom plate provided at the bottom of the case 112b of the wireless connection unit 112, a support plate extending upward from the rear end of the bottom plate, and a front end of the bottom plate and the It may include a tripod including an inclined plate connecting the top of the support plate.

As shown in [A] of Figure 11, an enclosure 80 is accommodated in the accommodation space. At this time, as the plate member 812 moves downward by the above-mentioned lifting means, the enclosure 80 connected to the plate member 812 moves downward, and the external wheel 814 moves along the inclined plate of the tripod. It moves forward as shown in [B] in Figure 11.

At this time, the enclosure 80 is hinged and rotated by the plate member 812 and the hinge 813, and as the plate member 812 moves further downward by the lifting means, the enclosure 80 moves as shown in Figure 11. It can be placed on the floor (parking surface) of the parking lot (P) as shown in [C].

In this way, this device includes an automatic arrangement means (8) including a transport means (81), so that the transmission pad (112a) accommodated in the accommodation space of the case (112b) of the wireless connection unit (112) connected to the transport device (6) can be automatically placed on the parking surface.

Conversely, when the plate member 812 is moved upward by the lifting means, the hinge 813 is unfolded and the enclosure 80 is accommodated in the receiving space again.

At this time, the vehicle to be charged is moved forward before the transmission pad 112a is placed on the floor by the above-described transportation means 81, and then the vehicle is moved backward after the transmission pad 112a is placed on the floor. There is a hassle of having to do it.

In order to eliminate the above-mentioned inconvenience, the automatic arrangement means 8 may include a depth adjustment means 82.

Referring to Figures 11 and 13, the depth adjustment means 82 is disposed inside the enclosure 80, and includes a body 821 to which the transmission pad 112a is connected, and an inner wheel connected to the lower part of the body 821. (822), and a driving means (823) (motor) that rotates the inner wheel (822). The driving means 823 can also be driven by receiving a signal from the control device 2 described above.

As the inner wheel 822 rotates in one direction while seated on the rear plate of the enclosure 80 (based on [A] in Figure 11), the body 821 moves forward from the inside of the enclosure 80. It can move outward (see [D] in Figure 11), and the inner wheel 822 mounted on the floor of the parking lot (P) can move inside the enclosure 80 by rotating in the opposite direction and moving rearward. (See [C] in Figure 11).

As such, the present system has the advantage of being able to move the transmitting pad 112a to the receiving pad side of the vehicle without moving the vehicle by including the automatic placement means 8 including the depth adjusting means 82.

Referring to FIGS. 11, 14, and 15, the automatic arrangement means 8 is disposed on the upper part of the body 821, and includes a rotary plate 831 to which the transmission pad 112a is connected, and a rotating plate 831 of the body 821. A rotation drive unit 835 (rotation motor) provided at the top and driven by a signal from the control device 2, and a rotation member 832 connected to the rotation drive unit 835 and rotating around the vertical direction as the central axis. , a first stick 833, one of which is connected to the rotating member 832 and the other connected to the rotating plate 831, one of which is connected to the rotating member 832 and the other is connected to the rotating plate. It may include rotation means 83 including a second stick 834 connected to 831.

The first stick 833 and the second stick 834 may be arranged in parallel when viewed on a plane, and the first stick 833 and the second stick 834 may be positioned relative to the center point of the rotating member 832. It may be connected to the rotating member 832 at the opposite position.

Therefore, when the rotation member 832 rotates in one direction as the shaft of the rotation drive unit 835 rotates, one of the first stick 833 and the second stick 834 moves toward the front and the first stick 833 ) and the other one of the second stick 834 moves toward the rear, and the rotating plate 831 can be rotated about the vertical direction with respect to the body 821 as the central axis (see [E] in FIG. 11).

That is, as the rotating member 832 rotates, the rotating plate 831 rotates, and the transmission pad 112a connected to the rotating plate 831 rotates.

In this way, since the present system includes the automatic arrangement means 8 including the rotation means 83, the transmission pad 112a can be rotated with the vertical direction as the central axis, so that it can be placed on the vehicle without moving the vehicle. Depending on the arrangement of the provided receiving pad, the transmitting pad 112a can be aligned with the receiving pad. In particular, the width of the transmitting pad 112a can be made larger than the width of the receiving pad (the outer diameter of the transmitting coil is larger than the outer diameter of the receiving coil). There is an advantage in that the transmission pad 112a (large) can be placed to improve charging efficiency.

Referring to Figures 11 and 15, the automatic positioning means 8 is provided on the rotating plate 831 and has a length parallel to the lateral direction, and an LM guide 841 is provided at the lower part of the transmission pad 112a. A block 842 that is fastened and moved to the LM guide 841, an alignment drive unit 843 provided (connected) to the rotating plate 831 and driven by a signal from the control device 2, and either end. A crank 844 is axially coupled to the shaft of the alignment drive unit 843 (e.g., a motor) so that the other one of the two ends rotates around one of the two ends, and one of the two ends is connected to the crank ( 844) and the other may include an alignment means 84 including a connecting link 854 (Connecting Link) connected to the transmission pad 112a.

To be more specific, the alignment driving unit 843 allows the upper key crank 844 to rotate (rotate in the vertical direction about the central axis) about one of the two ends of which the other end is connected to the alignment driving unit 843, The connecting link 845 connected to the end of the crank 844 is rotated around the point where it is connected to the crank 844 (rotated in the vertical direction about the central axis), thereby connecting the end of the connecting link 845. The transmission pad 112a can move (crank-slide mechanism) along the longitudinal direction of the LM guide 841.

Therefore, even when the transmission pad 112a is moved forward by the depth adjustment means 82, the transmission pad 112a can be further moved forward and backward.

In addition, as described above, it is said that the rotating plate 831 provided with the LM guide 841 can be rotated about the vertical direction as the central axis, and the alignment means 84 provided or connected to the rotating plate 831 can also rotate about the vertical direction. Therefore, when the rotary plate 831 is rotated, the transmission pad 831 can be moved in a direction perpendicular to the direction of movement of the body 821 when viewed on a plane.

Therefore, there is an advantage that the transmitting pad 831 can be moved to be aligned with the receiving pad without moving the vehicle.
