Description

  The present invention relates to a device for supplying power to a storage battery of an electric vehicle stored in a mechanical parking device.

  A mechanical parking device is used to solve parking difficulties in the suburbs of the city, by stacking multiple parking rooms for storing cars, and placing cars between the parking device entrance and exit and each parking room. Various types of mechanical parking devices have been put into practical use as equipment or devices for installing and transporting a mounted and transporting vehicle to store and park an automobile in three dimensions.

  In addition, automobiles also store electricity by storing storage batteries from conventional automobiles that use fossil fuels such as gasoline and light oil due to global warming problems. A so-called electric vehicle for obtaining the above has been put into practical use.

  As described above, since an electric vehicle has a drawback that it takes a long time for charging in order to charge the storage battery with electric power as a driving force, it is intended to charge the battery during a time when the vehicle is not used. As one of the methods, various mechanical parking apparatuses that can charge an electric vehicle using parking time have been proposed in the mechanical parking apparatus according to the present invention.

Figure 5 shows a front view of an elevator-type parking apparatus 100 provided with a charging device which is provided commonly widely charging device with mechanical parking car device. In the figure, a cage 109 positioned in a pit 102 is suspended in suspension shafts 110, 110,..., For example, a rope, a chain, etc., and vertically moved by a drum 112, 112,. Go up and down. Above the entrance / exit level 106, right parking rooms 104a, 104a,... And left parking rooms 104b, 104b,. Each of the right-side parking chambers 104a, 104a,... And the left-side parking chambers 104b, 104b,. The entrance / exit 108 of the automobile is set at the level of the ground surface. Further, the cage 109 is equipped with a transfer device (not shown) for horizontally feeding the tray 120 toward the right parking chambers 104a, 104a,... Or the left parking chambers 104b, 104b,.

  Further, in the drawing, the right power supply line 141a is supported on the structure 101 by the supports 143, 143,... On the side of one of the right parking rooms 104a, 104a,. , 104b, the left power supply line 141b is supported by supporting members 143, 143,. Further, the right power supply line 141a is connected to a right power supply 140a provided in the loading / unloading chamber 107, and the left power supply line 141b is connected to the left power supply 140b and is supplied with power.
