  Preferred embodiments of the present invention are shown below.

  The vehicle charging device of the invention has a power feeding means inside a column-shaped casing 1 and includes a charging cable 8 for energizing the power feeding means and the electric vehicle. At the tip of the charging cable 8, there is a charging connector 2 that is connected to a power feeding portion provided in the electric vehicle.

  A charging connector holding space 7 for holding the charging connector 2 in the casing 1 when not in use is provided on the front surface of the casing 1, and a display device 3 is provided on the top of the casing 1. Further, the right side surface of the housing 1 is provided with an inspection door 4, and the left side surface is provided with a charging cable holding surface 5 provided with a cable latch 51 for winding the charging cable 8 as shown in FIG. ing.

  The casing 1 includes a CPLT, an authentication device, a circuit breaker, and the like, and as shown in FIG. 2, an iron substrate 6 on which these devices are installed is installed on the left side of the casing. A charging connector holding space 7 is provided at the center of the inside of the housing 1, and the iron substrate 6 is vertically divided with the charging connector holding space 7 in between. In addition, a heater is disposed inside the housing 1 as a countermeasure against condensation.

  The power source introduced from the ground passes through a relay or the like inside the housing 1 and then is drawn out from a cable outlet 9 provided on the left side surface of the housing 1 as shown in FIG.

  As shown in FIG. 3, a cable locking member 51 is provided on the charging cable holding surface 5. As shown in FIGS. 5 to 7, the charging cable 8 when not in use can be wound around the cable locking member 51 with an appropriate number of turns.

  A cable guard 52 is disposed along the left and right sides of the charging cable holding surface 5 outside the charging cable 8 wound and held by the cable locking tool 51. In the present embodiment, the left and right end portions of the charging cable holding surface 5 are extended in a direction perpendicular to the charging cable holding surface 5 to form a pair of left and right cable guards 52.

  The cable guard 52 is preferably formed in a substantially U-shape and has a structure for holding the outer periphery of the charging cable 8 wound around the cable locking tool 51 as shown in FIG.

  The vertical height (H) of the cable guard 52 with respect to the charging cable holding surface 5 is preferably equal to or higher than the winding height (H ′) of the charging cable 8 wound around the cable locking tool 51. With this structure, the vertical height (H) of the cable guard 52 is equal to or higher than the vertical height (H ′) of the charging cable 8 wound around the cable locking tool 51 with respect to the charging cable holding surface 5. It is possible to reliably protect the charging cable. In the present embodiment, as shown in FIG. 7, the height (H) of the cable guard 52 in the vertical direction is equal to or higher than the height of the cable locking member 51 in the protruding direction with respect to the charging cable holding surface 5.

  In the present embodiment, the description has been made assuming that the cable locking tool 51 and the cable guard 52 are respectively attached to the charging cable holding surface 5. However, the cable locking tool 51 and the cable guard 52 are integrated with a resin material or the like. The charging cable holding surface 5 may be formed and attached to one side surface of the housing.

  In this way, the configuration including the cable guard 52 allows the charging cable 8 when not in use to be held compactly without protruding from the cable guard 52, and thus is wound around the cable lock 51 when not in use. It is possible to avoid problems that the charging cable 8 impairs the appearance of the appearance or obstructs traffic. In addition, it is possible to effectively prevent an accident such as the charging cable 8 wound around the cable locking tool 51 being caught by a pedestrian or vehicle passing near the charging cable holding surface 5.

  When the charging cable 8 is sufficiently soft, as shown in FIG. 11, the charging cable 8 wound around the cable locking tool 51 droops greatly in the vertical direction, and the outer periphery thereof is not held by the cable guard 52. Even in this case, the wound charging cable 8 is within the range of the vertical height (H) of the cable guard 52 as shown in FIG. It is possible to effectively prevent accidents such as the charging cable 8 wound around the cable locking member 51 being caught by a pedestrian or vehicle.

It is preferable that the cable guard 52 is formed in a series over the support column. This is because when the charging cable is wound, it becomes a circle extending in the vertical direction in order to wind it appropriately. However, the present invention is not limited to this, and the cable guard may be partially provided in the vertical direction.
For example, a plurality of cable guards 52 having a predetermined length may be provided at predetermined intervals in a pair of left and right sides in the vertical direction. With such a configuration, the charging cable 8 can be drawn out from between the adjacent cable guards 52 to the front charging connector holding space 7, and the charging cable 8 does not protrude from the cable guard 52.

In the present embodiment, the cable guard 52 is formed by extending the left and right ends of the charging cable holding surface 5 from the charging cable holding surface 5, but the cable guard 52 is formed with respect to the cable holding surface 5. It is not necessary to be formed vertically. For example, the cable guards 52 formed as a pair may be provided so as to be inclined inward from each other as shown in FIG.
In addition to the substantially U-shape, the cable guard 52 has an L-shape as shown in FIGS. 10A to 10C, one side of the U-shape inclined outward, and one side of the U-shape on an arc. Although it is good also as a shape etc. which incline, it is preferable that all are more than the height (H ') of the perpendicular direction with respect to the charging cable holding surface 5 of the charging cable 8 wound up by the cable latching tool 51. FIG.

  As shown in FIG. 8, the cable locking tool 51 can be provided in a pair of upper and lower sides to wind up the charging cable 8.

In addition, as shown in FIGS. 3 and 5, a cable outlet 9 is formed at the lower portion of the cable locking member 51 to draw out the charging cable from the inside of the housing 1. The cable outlet 9 is preferably formed on the surface where the cable guard 52 is provided.
The cable outlet 9 is arranged so as to be shifted in one direction with respect to the center position of the left side surface. Thereby, the cable locking tool 51 can be held smoothly while drawing the charging cable 8 drawn in an arc. Moreover, it can make it easy to enter the cable guard 52 formed in a U-shape.

  The cable outlet 9 is formed to be recessed inside the side surface, and has a structure in which the upper surface is inclined downward toward the inner side and the lower surface is inclined outward toward the inner side. Since the cable lead-out part 10 is installed on the upper surface of the cable lead-out opening 9, even when the charging cable 8 is wound around, the cable lead-out part 10 is not subjected to an excessive load and the charging cable 8 is not damaged. Protrusion of the cable lead-out portion 10 can be suppressed by adopting a structure in which the cable lead-out opening 9 is recessed in the housing. By making the lower surface of the cable outlet 9 an inclined structure, an excessive external force is not applied when the charging cable 8 is pulled out.
