Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing device for a connector cover provided on at least one of a head portion and a back portion of a vehicle body and mainly used for connecting to another vehicle in an emergency.

[0002]

2. Description of the Related Art A coupling cover of this type is mainly used for a Shinkansen vehicle. Conventionally, a coupling cover has a structure which can be manually detached by a driver or the like by removing bolts or the like. It is a target.

As another prior art, as disclosed in Japanese Utility Model Registration No. 2558830, Japanese Utility Model Application Laid-Open No. 60-84359 or Japanese Utility Model Application Laid-Open No. 3-50582, a pair of half covers is provided. There is a structure in which a split cover is stored in an opening of a vehicle body when the split cover is opened.

[0004]

However, in order to reduce the generation of micro-pressure waves generated when entering a tunnel,
For example, in a vehicle in which a measure such as a configuration in which the lower part of the leading end of the vehicle is spread out in a “duck beak” shape or the like is taken, the above-described conventional coupler cover cannot be used for the following reasons. That is, since the entire shape of the cover becomes very large and the weight increases, it cannot be handled by one or two persons unless it is divided into many parts.

[0005] When the vicinity of the lower part of the leading end has a complicated shape, and the half-cover structure described in the above publication is used,
There is no space in the opening of the car body to store the half-split cover.

[0006] The connector cover described in the above publication is based on the premise that the connector is frequently used, and is mechanically operated (electrically driven) so as to be automatically opened and closed.
The structure is complicated and heavy, making it unsuitable as a connector cover used only in an emergency.

[0007] The head of a conventional Shinkansen vehicle has a streamline shape, and its width gradually becomes narrower and sharper toward its tip. However, the head with a countermeasure against micro-pressure waves has a considerably larger width than the conventional one. It is getting wider. For this reason, unless the opening on the vehicle body side where the coupler is exposed is made considerably large so that the projecting amount of the coupler becomes considerably larger than in the past, a vehicle having a leading end of the vehicle body connected when traveling on a curved road ( There is a possibility that the vehicle may not be able to travel due to contact with the body of the towing vehicle.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and enables a single operator to easily open and close a large-sized and heavy-weight cover body, and has a relatively small space with a simple structure.
