Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure which is recessed in an outer surface of an electric vehicle to remove water in a storage chamber for storing a charging connector therein.

[0002]

2. Description of the Related Art Conventionally, as a means for removing moisture in a storage chamber formed by opening an outer surface of a vehicle body for storing a charging connector for an electric vehicle, as shown in FIG. There is a water discharge port b provided so that the water adhering to the inner surface of the storage chamber a flows down along the inner surface and is discharged from the water discharge port b to the outside of the storage chamber a.

[0003]

According to such means, the water on the substantially vertical inner wall surface c and the side wall surface d of the storage chamber a flows down well. However, the ceiling surface e and the floor surface f are substantially horizontal, so that the water adhering to the ceiling surface e does not flow to the inner wall surface c or the side wall surface d and falls as it is, and this dropped water is used for charging. The connector g may get wet, while
On the floor surface f, water may be accumulated on the back wall surface c side due to the inclination of the vehicle body during traveling, and the accumulated water may wet the charging connector g. As described above, in the conventional means, since the charging connector g is easily wet with water, there is a risk that water may come into contact with the exposed terminals of the charging connector g to cause an electric leakage or a short circuit.

The present invention was devised in view of the above circumstances, and an object thereof is to prevent the charging connector from getting wet to avoid the risk of electric leakage or short circuit.

[0005]

SUMMARY OF THE INVENTION According to the present invention, an electric vehicle body has an accommodating chamber which is opened at an outer surface of the electric vehicle so as to form a recess, and the charging connector is exposed in the accommodating chamber. The feature is that the structure is such that an inclined surface is formed on the inner surface.

In the above structure, the inner surface of the storage chamber may be subjected to a water repellent treatment, or the water collecting groove may be formed on the inner surface of the storage chamber, and the drain port is provided near the opening edge of the storage chamber. The structure may be provided, or the cover provided at the opening of the storage chamber may be provided with heating means for heating the storage chamber.

[0007]

When the ceiling surface of the storage chamber is inclined toward the back or side, the water adhering to the ceiling surface does not drop onto the charging connector protruding into the storage chamber and the back wall surface or side It is guided by the wall surface and flows down along the inner wall surface or side wall surface.

If the floor surface is an inclined surface that descends toward the opening edge of the storage chamber, the water on the floor surface will not collect on the back wall surface side of the storage chamber even if the vehicle body tilts, and the like. It is guided from the back side toward the opening side.

Further, when the inner surface of the storage chamber is subjected to the water repellent treatment, the flow of water becomes smooth. When the water collecting groove is formed on the inner surface of the storage chamber, the water traveling along the inner surface can be collected in the water collecting groove to flow through the path avoiding the charging connector. When the drain port is provided in the vicinity of the opening edge of the storage chamber, water does not run down from the opening edge of the storage chamber to the outer surface of the vehicle body. When the heating means is provided on the cover provided at the opening of the storage chamber, the storage chamber is heated and water adhering to the inner surface of the storage chamber evaporates.

[0010]

As described above, according to the present invention, there is no possibility that water dropped from the ceiling surface of the accommodation chamber or water accumulated on the back wall surface side of the floor will wet the charging connector, and thus charging will be performed. There is an excellent effect that it is possible to prevent the occurrence of electric leakage and short circuit due to the wetting of the connector for use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment embodying the present invention will be described below with reference to FIGS.

A vehicle body 1 of an electric vehicle is provided with a housing chamber 2 having a rectangular opening on the outer surface thereof. At the opening of the accommodation chamber 2, a cover 3 that swings and opens around its upper edge is opened.
The charging connector 5 protruding from the vertical back wall surface 4 is housed inside the housing chamber 2. A charger-side connector (not shown) is connected to the charging connector 5, whereby a vehicle-mounted battery (not shown) is charged.

The ceiling surface 6 of the accommodation chamber 2 extends from the opening side to the inner wall surface 4
It has an inclined surface that descends toward the side. Also, floor 7
Is a bilaterally sloping surface that descends from the back wall surface 4 side toward the opening side, which is the opposite of the ceiling surface 6, and more specifically descends from the left and right wall surfaces 8 and 8 toward the center.

A ceiling surface 6 and a back wall surface 4 are provided on the inner surface of the accommodation chamber 2.
A substantially rectangular shape that avoids the charging connector 5 along a continuous edge with the back wall surface 4, the left and right side wall surfaces 8 and 8, and a continuous edge between the floor surface 7 and the back wall surface 4. A water collecting groove 9 is formed along the path. Further, in the water collecting groove 9, a drain groove 10 is continuously formed along the lowest valley line between the left and right symmetrical inclined surfaces of the floor surface 7.

The drainage groove 10 is connected to a drainage port 11 which opens on the floor 7 in the vicinity of the opening of the storage chamber 2. The drainage port 11 has a lower end (not shown) located outside the vehicle body. 12 is installed.

The surfaces of the inner wall surface 4, the ceiling surface 6, the floor surface 7, the side wall surface 8, the water collection groove 9 and the drain groove 10 of the storage chamber 2 are
Water repellent treatment such as Teflon coating is applied.

Further, the cover 3 attached to the opening of the accommodation chamber 2
Is provided with heating means such as stretching a heating wire on its inner surface.

Next, the operation of this embodiment will be described.

When water adheres to the inner surface of the storage chamber 2, the water on the ceiling surface 6 slides by the water-repellent treatment according to the inclination and flows toward the inner wall surface 4 side to reach the water collecting groove 9 and reach the water collecting groove 9 Then, the water is discharged to the outside of the storage chamber 2 by sequentially passing through the drainage groove 10, the drainage port 11, and the hose 12.

Water adhering to the vertical inner wall surface 4 slides down along the surface by the water repellent treatment and reaches the water collecting groove 9, and reaches the water collecting groove 9, drainage groove 10, drainage port 11 and hose 1.
It is discharged to the outside of the accommodation chamber 2 by passing through 2 in order.

Similarly, the water adhering to the vertical side wall surface 8 slid down along the surface due to the water-repellent treatment and reaches the floor surface 7, and together with the water adhering to the floor surface 7, the left and right sides of the water. It reaches the drainage groove 10 by sliding according to a water-repellent treatment according to a symmetrical inclination, and is discharged to the outside of the accommodation chamber 2 by passing through the drainage port 11 and the hose 12.

Even if a part of the water on the inner surface of the storage chamber 2 remains attached without flowing as described above, the heating means provided in the cover 3 is operated to heat the inside of the storage chamber 2. Thereby, the water adhering to the inner surface is evaporated and removed. Further, the water attached to the surface of the charging connector 5 is also evaporated and removed by the operation of the heating means. Therefore,
Water can be completely removed from the storage chamber 2.

The heating means can be omitted. That is, when the heating means is omitted, even if water adheres to the inner surface of the housing chamber 2, the charging connector 5 may get wet because the adhesion to the portion directly above the charging connector 5 on the inner wall surface 4 is small. Only the amount of water, most of the water adhering to the inner surface of the storage chamber 2 is discharged to the outside of the storage chamber 2 without wetting the charging connector 5. Therefore, there is very little risk that an electric leakage or a short circuit will occur due to the charging connector 5 getting wet.

Further, since the discharged water does not flow out from the opening of the accommodating chamber 2 to the outer surface of the vehicle body 1, the appearance of the vehicle body 1 will not be impaired by the trace of the water flow.

The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention.
