DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The figure shows an example of application to a large bus, in which a bus 1 is a generator 3 driven by an engine 2.
And a large number of capacitors 6 that store the generated power,
Electric motors 4 and 5 for vehicle running driven by these power sources
And

When the electric motors 4 and 5 are supplied with current from the capacitor 6 through the inverter 7, they output a rotational force (driving force) for traveling the vehicle. The rotation is decelerated by the gear box 8 and transmitted from the propeller shaft 9 to the left and right drive wheels 10 via the differential.

In order to mount a large number of capacitors 6 on a vehicle, a storage chamber 13 (capacitor chamber) having a predetermined volume is provided between the roof 11 and the ceiling 12 (attic of the vehicle interior). The floor is divided into a plurality of sections, and each section is formed on a ceiling plate 14 that can be opened and closed. The hinges 15 are arranged on both sides of the roof, and the ceiling plates 14 are supported rotatably in the vertical direction via the hinges 15 on one side.

Each ceiling plate 14 is attached to a bracket 16 (which is connected to the frame of the vehicle body) extending in the front-rear direction at the center of the ceiling 12.
The stoppers 17 for fixing the ∘ at the closed position are rotatably attached via the pins 18 at the respective intermediate portions.

Both ends of these stoppers 17 are locking portions 17a.
And is commonly used for the ceiling plate 14 that is symmetrical about the vehicle body side bracket 16. A bolt hole is formed in the locking portion 17a, and the nut 19 of the ceiling board 14 is passed through this hole.
Further, a bolt 20 for tightening the stopper 17 is provided.

The unit box 21 of the capacitor 6 is provided on the inner surface (attic side) of each ceiling plate 14. The unit box 21 accommodates a predetermined number of capacitors 6, and a pair of electrodes 22 are projectingly provided on the surface of the box, and a wiring (not shown) for connecting the capacitors 6 inside the box in series between the electrodes 22. ) Is provided.

The pair of electrodes 22 is not shown, but the generator 3
Side charging connector and the output connectors of the electric motors 4 and 5 are respectively connected in a predetermined wiring state, and the lengths of these wirings (not shown) set a margin (slack) that allows opening and closing of each ceiling board 14. To be done.

The unit box 21 is fixed to the inner surface of the ceiling plate 14 via a bracket 24 with bolts and nuts. When the ceiling plate 14 is unfixed at the closed position, it is supported at a predetermined inclination angle (opening angle) via a damper 25, which will be described below.
In order to prevent the unit box 21 from falling off, a support plate 26 that locks the lower side surface of the unit box 21 that is inclined together with the ceiling plate 14 is provided in a protruding manner.

A damper 25 is provided between the roof 11 and the ceiling plate 14.
Is installed. The damper 25 is rotatably pin-connected to a roof-side bracket 27 on the head side and a ceiling-side bracket 28 on the rod side. The plate 14 is supported at a predetermined inclination angle (that is, the ceiling plate 1
The opening angle of 4 is regulated).

With such a configuration, the capacitors 6 are housed in the unit boxes 21 of the respective ceiling plates 14, and by fixing these ceiling plates 14 to the closed position, the space of the passenger compartment is not greatly sacrificed, It can be stored in the storage room 13 in the attic in a good appearance.

During inspection or maintenance, when the bolt 20 of the stopper 17 is removed to unlock the ceiling plate 14, the ceiling plate 14 is pivoted toward the passenger compartment with the weight of the hinge 15 as a fulcrum. At that time, since the damper 25 damps the opening speed of the ceiling plate 14, the ceiling plate 14 is safely opened to the passenger compartment side.

The damper 25 supports the ceiling plate 14 at a predetermined inclination angle in the open position. When the connection by the bracket 24 is released in this state, the unit box 21 can be detached from the ceiling plate 14 by removing the wiring on the charging side and the output side from the electrode 22, so that it can be carried out to the outside.

Therefore, inspection and maintenance can be processed easily and efficiently. The unit box 21 that tilts together with the ceiling plate 14 even if the connection by the bracket 24 is released
Is supported by the support plate 26 so as not to fall off, so that removal from the ceiling plate 14 can be performed safely and easily.

Also for the subsequent storage, since the capacitors 6 are stored in a unit box 21 of each ceiling plate 14 in a fixed number, they can be pushed up by a light load and stored in the storage room 13 in the attic.

As described above, it is possible to effectively use the roof portion of the vehicle as a storage place for a large number of capacitors 6 while ensuring the ease of inspection and maintenance. The unit box 21 may not be provided, and the capacitor 6 may be directly arranged on the inner surface of the ceiling plate 14. Further, instead of the damper 25, a hydraulic actuator may be provided so that the ceiling plate 14 can be opened and closed by a switch operation or the like.
