Description

  The present invention relates to a charging device for a motor vehicle provided, for example, in an electric car, a plug-in hybrid car, etc., and more particularly to a technical field of a structure for improving sealing performance.

  2. Description of the Related Art In recent years, the spread of electric vehicles and plug-in hybrid vehicles that can be driven by electric power stored in a driving battery has been promoted. These vehicles are provided with a charging inlet for connecting a feeding plug at the end of a charging cable extending from the charging facility, and when charging the traveling battery, the charging plug is connected to the charging inlet and then the charging inlet is connected to the charging inlet. Power feeding is to be started.

  Generally, a car equipped with a battery for traveling is provided with a car charging device including the above charging inlet (see, for example, Patent Document 1). The vehicle charging device of Patent Document 1 includes a reinforcing element formed of a sheet metal part, a charging socket attached to the reinforcing element via an adapter device, and a charging cradle for sealing between the outer surface of the vehicle body and the charging socket. Have. A cylindrical adapter ring is fixed to the peripheral portion of the charging socket. The charging cradle is formed with an opening into which the adapter ring is inserted. The peripheral edge of the opening is provided with a sealing element made of a rubber component, such that the sealing element contacts the outer peripheral surface of the adapter ring.

Patent No. 6006143

  By the way, in general, the reinforcing element of the vehicle charging device of Patent Document 1 is fixed to the inner panel of the vehicle body, while the charging cradle is fixed to the outer panel of the vehicle body. At this time, since the relative positional relationship between the inner panel and the outer panel differs for each vehicle body due to a manufacturing error, the positional relationship between the reinforcing element and the charging cradle also differs for each vehicle body. Since the charging socket is fixed to the reinforcing element and the adapter ring is fixed to this charging socket, the positional relationship between the adapter ring and the charging cradle differs depending on the vehicle body. It is believed that the provision of the sealing element made of a rubber component allows the deformation of the sealing element to absorb changes in the relative position of the adapter ring and the charging cradle.

  However, in Patent Document 1, the charging socket and the adapter ring are adhesively fixed, but the charging cradle and the adapter ring are only the adapter ring because the sealing element of the charging cradle is in contact with the outer peripheral surface of the adapter ring. If the seal element is deformed due to a change in the relative position of the charging cradle and the charging cradle, a gap is likely to be formed between the seal element and the outer peripheral surface of the adapter ring, which may deteriorate the sealing performance. If the sealing performance is deteriorated, a problem such as a short circuit may occur if rain water or water at the time of car washing intrudes into the interior of the vehicle body from between the sealing element and the outer peripheral surface of the adapter ring.

The inner peripheral side thick portion 36 is sandwiched between the flange portion 21 and the inner peripheral side portion 5 a of the plate 5 in the thickness direction to be elastically deformed. Thereby, the inner peripheral side thick portion 36 is in close contact with the flange portion 21 and the inner peripheral side portion 5 a of the plate 5. In this embodiment, the inner peripheral portion 5 a of the plate 5 is a pressing portion that presses the inner peripheral thick portion 36 of the seal plate portion 34. Further, since the portion of the seal plate portion 34 in contact with the plate 5 is formed thicker than the portion of the seal plate portion 34 not in contact with the plate 5, the plate 5 is brought into contact with the plate 5 with certainty. It can be elastically deformed along 5 and can be elastically deformed along the flange portion 21. Therefore, the sealability between the seal plate portion 34 and the flange portion 21 can be further enhanced.

In this embodiment, since the seal portion 31 is made of an elastic material and has a bent portion 31a, the relative position change between the charge inlet 2 and the inlet housing 3 is caused by the elastic deformation of the seal portion 31. It can be absorbed.

  The seal portion 31 is held between the flange portion 21 of the charge inlet 2 and the plate 5 to be elastically deformed. At this time, since the plate 5 is subjected to bending so that the inner circumferential side portion 5a of the plate 5 is positioned inward of the outer circumferential side portion 5b, the rigidity of the plate 5 is enhanced. Plate portion 34 can be reliably pressed over the entire periphery of the outer surface of flange portion 21 of charge inlet 2. Thus, the seal plate portion 34 is in close contact with the outer surface of the flange portion 21 of the charge inlet 2 to secure sealing performance.
