Further, the vertical direction Y is shown in FIGS. 6-2 (insertion with the guide rod shifted downward) and FIG. 6-3 (insertion with the guide rod shifted upward). The movable plate 3 is moved by the spring 2 in order to move in the horizontal direction X and / or in the vertical direction Y. Therefore, it is possible to move in all directions, and it is very useful because it is possible to achieve flexibility and ease of feeding, or reliable feeding. Further, it is desirable to use a guide rail, a guide post, a guiding robot, etc. (not shown) to move the movable plate 3 in the horizontal direction X and / or the vertical direction Y.

  The magnet 8 attracts a magnet (described later) provided on the base C3 of the rear portion C1 of the vehicle C, and fixes the vehicle C during power feeding. This mainly restricts the useless movement of the vehicle C that is being fed and prevents accidents during feeding.

  In the figure, reference numeral 11 denotes a switch provided at the end 3a (3b) of the movable plate 3 at a slight interval to notify the completion of warehousing. This switch 11 is one of the bases C3 of the rear C1 of the vehicle C. It is a structure that is turned on when it comes into contact with the contact 12 provided at the end and turned off when it is separated. And in the case of ON, the 1st electric lamp 13 (display tools, such as an indicator lamp and LED) provided in the garage A (or electric power feeder) lights. When this first electric light 13 is turned on, it is in a state where there is a warehouse. It is desirable that the switch 11 be able to cope with each traveling state (up / down, displacement, etc.) of the vehicle C, which will be described later, by performing the same movement (interlocking mechanism) as the movable plate 3.

  In the figure, reference numeral 20 denotes a power supply unit, and this power supply unit 20 is provided at a rear portion C1 of the vehicle C (not shown, but there may be a front portion C2 of the vehicle C). And it is the structure which does not protrude outside a vehicle.

  The power supply unit 20 is provided with a pair of fixed contacts 21 on both sides of the center C in the width direction Q of the base C3 of the rear portion C1 of the vehicle C (the front portion C2 of the vehicle C). 21 is provided in an insulator 22 provided on the base C3 so as to be able to appear and retract. By adjusting the protrusions and depressions from the insulator 22 (adjusting the protrusion length), reliable contact with the spring contact 7 and adjustment of the reaction force of the spring contact 7 are achieved. A cord 23 is connected to the fixed contact 21, and a second electric lamp 25 is provided at the tip of the cord 23. The second electric lamp 25 is lit when the spring contact 7 and the fixed contact 21 are in contact with each other. This second electric light 25 is provided in one place or several lights at an appropriate place in the vehicle C, for example. A magnet 26 is provided between the fixed contacts 21 (the magnet 26 is magnetically attached to the magnet 8). Reference numeral 27 in the figure denotes guide rods provided on both ends of the base C3 in the width direction Q on the outside of the fixed contact 21, and the pair of guide rods 27 are inserted into the pair of concave portions 500 of the derivative 5. Is done. The relationship between the guide rod 27 and the recess 500 is as described above.

  In the figure, reference numeral 30 denotes a guide rail, and the guide rail 30 has a long and short structure and the entrance side is widened so that it can be easily inserted. Reference numeral 31 denotes a vehicle C stopper.

  Hereinafter, the storage of the vehicle C and the power supply situation will be described. As shown in FIGS. 1 and 2, the vehicle C is backed (not shown, but can be moved forward) and stored. By running, the power supply state shown in FIGS. The process will be described based on the main part shown in FIGS. 5-1 to 5-4. As shown in FIGS. 5-1 and 6-1-1, the guide toward the concave portion 500 of the derivative 5 is guided. As the collar 27 is inserted (entered), the fixed contact 21 and the magnet 26 approach the spring contact 7 and the magnet 8, respectively. FIG. 5B shows a state in which the insertion state and the approach have advanced. In this state, the contact 12 is brought into contact with the switch 11 so that the vehicle C enters the predetermined state, and the first electric light 13 Lights up. By this lighting, it can be confirmed that the goods have been received smoothly, which is beneficial and can be relieved. Then, as shown in FIG. 5C, the fixed contact 21 comes into contact with the spring contact 7 in the process in which the guide rod 27 reaches the bottom of the recess 500. The second electric lamp 25 is turned on through this contact. With this lighting, it can be understood that power is supplied to the battery C4 of the vehicle C, and there is an advantage that it can be relieved, that the vehicle has been stored smoothly, or that power is being supplied. In addition, the 2nd electric light 25 can also be installed in the inside of a vehicle and other accessory places. 5-4 and FIG. 6-1 show that the vehicle C and the guide rod 27 reach the bottom of the recess 500 when the vehicle C and the guide rod 27 move backward, and the magnets 8 and 26 are attracted to attract the vehicle. It shows that the fixed state of C is secured and the last state where power feeding is continued.

  The above describes the situation in which the vehicle C is traveling and the guide rod 27 is at a substantially predetermined level X1 in the horizontal direction X and moves backward smoothly, as shown in FIGS. 6-2 and 6-3. In the up-and-down direction Y, it can be considered that the lower X2 and the upper X3 are in the level X1. Explaining this state, for example, as shown in 6-2, when the guide rod 27 is in the downward state and is inserted into the recess 500 (when entering), the movable plate 3 is temporarily pushed downward and the spring 2 is pushed down, and the power is supplied in a state where the movable plate 3 is lowered, but there is no problem because the compressed state of the spring 2 is ensured. On the contrary, as shown in FIG. 6-3, when the guide rod 27 is inserted into the recess 500 in the upward state, the movable plate 3 is temporarily pushed upward and the spring 2 is extended. The power is supplied with the movable plate 3 raised, but there is no problem because the extended state of the spring 2 is ensured. Accordingly, it is possible to cope with the height of the height, the size of the tire air pressure, the height of the insulator 22, and the like. At this time, the movement of the movable plate 3 effectively works by adopting the spring contact 7 with respect to the fixed contact 21 (the same applies hereinafter).

  Further, in the traveling of the vehicle C, the guide rod 27 is located at the approximate center Q1 between the guide rails 30 in the width direction Q (in other words, the center Y1 in the horizontal direction Y) and smoothly retreats (see FIG. 5-1 to FIG. 5-4). However, the vehicle C does not necessarily have such a situation. For example, as shown in FIGS. 9-1 and 9-2, in the vertical direction Y, the displacement Y2 to the left with respect to the center Y1, and the displacement Y3 to the right. It is conceivable that Explaining this state, for example, as shown in 9-1, when the guide rod 27 is inserted into the concave portion 500 with the displacement Y2 to the left, the movable plate 3 is temporarily moved to the left with the displacement Y2 (pushing). In this state, the spring 2 is bent to the left and the movable plate 3 is moved to the left, and the power is supplied. However, the problem arises because the spring 2 is bent to the left. Absent. On the contrary, as shown in FIG. 9-2, when the guide rod 27 is inserted into the concave portion 500 with the displacement Y3 to the right, the movable plate 3 is temporarily moved to the right with the displacement Y3 (pressed). State), the spring 2 is bent to the right, and the movable plate 3 is moved to the right, and the power is supplied. However, there is no problem because the spring 2 is bent to the right. Others are based on the above example.

  Further, although not shown, it is possible that the vertical movement of the guide rod 27 and the left / right displacement occur comprehensively. In this case, there is no problem if the above-described movement can be secured.

  In the figure, reference numeral 40 denotes a plug connected to a household power source, and 41 denotes a household battery (for business use, factory use, etc.).

  Each structure described above is a description of a preferred example of the present invention. Therefore, the present invention is not limited to the above-described embodiments, and structures that change a part of the configuration within the scope of the invention, structures that can achieve the same features and effects, and the like are within the scope of the present invention.
