Description

[Detailed Description of the Invention] This invention relates to a vehicle power supply device that is installed in a vehicle such as a large bus.

For example, in large buses such as regular buses and sightseeing buses, passengers line up in a single line to get on and off, so when getting on and off, passengers often stand near the entrance. The problem with these vehicles is that passengers get wet when getting on and off the vehicle during rainy or snowy weather, reducing the ease of getting on and off the vehicle.

The present invention has been made to solve these difficulties, and the purpose of the present invention is to provide a vehicle safety device that prevents passengers from getting wet when getting on and off the vehicle during rainy or snowy weather. There is a particular thing.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

FIG. 1 is a diagram showing the appearance of the implementation side bottom device installed at the front entrance 2 of the bus body 1. In this device, a bread-shaped eave 3 is installed on the roof surface above the entrance 2. is installed, and when the door 4 is opened, the eaves 3, which is slightly wider than the width of the entrance/exit 2, is automatically extended 50 cm to the side of the vehicle body, as shown in Figures 2 and 3. It can be extended to a certain extent and placed above the passengers.

The mounting structure of the eaves 3 will be explained below with reference to FIG. 4 (rear view) and FIG. 5 (separated view).

An angle-shaped bracket 6.7 is fixed on the side of the roof panel 5 above the entrance/exit, on the width line of the vehicle body corresponding to the center of the entrance/exit. A longitudinal base plate 8 is installed between the upper surfaces,
On the plywood 8, an elongated groove rail 9 with a guide groove as a guide member opened on the upper surface is fixed, and a mounting plate 11 for an air cylinder 10 is also fixed.

In addition, two brackets (12.13) are fixed in parallel in the width direction of the vehicle body on the front and rear roof panels 5 of the bed plate 8 near the vehicle body side ends, respectively. 1
Guide rollers 14 and 15 for holding both sides of the eaves 3 are pivotally attached to the eaves 2 and 13.

Furthermore, a pivot 1 is attached to the end of the groove rail 9 near the center line of the vehicle body.
6 is fixed upward, and a lever 17, which is a lever 17 formed integrally by folding a short arm 17a and a long arm 17b, is rotatably attached to the pivot shaft 16. The tip of the arm 17H is pivotally connected to the tip of the operating rod 18 of the air cylinder 10.

In addition, a sliding roller 20 is inserted into the groove of the groove rail 9, and a loose shaft 21 of the roller 20 rises from the groove rail 9, and its upper end has a threaded portion fixed to the eaves 3. is forming.

The loose shaft 21 and the tip of the long arm 17b of the lever 17 are connected via a straight lever 24, which is a second lever. The actuating rod 1 of the air cylinder 10 is driven by the rotation and slides in the groove rail 9 in a pantograph shape.
In the operating position where 8 is the most protruding, the loose shaft 21 moves toward the side end of the groove rail 9.

Next, the eaves 3 is formed into a bread shape by a top plate 3a and ear plates 3b on both the front and rear sides, and longitudinal groove frames 22 are fixedly fixed to the inner wall surfaces of both ear plates 3b so as to face each other. The frontage edge of this groove frame 22 is inserted through guide rollers 14 and 15.

Further, a tap plate 23 is fixedly installed near the back of the center of the top plate 3a, and the upper end of the loose shaft 21 of the sliding roller 20 is
It is fastened to this tap plate 23.

The eaves 3 of the embodiment is attached to the roof panel 5 as described above, but the air cylinder 10 is equipped with an operating mechanism (described later).
In addition to protruding the operating rod 18 by supplying dynamic pressure air from the air cylinder 10, a return spring is installed inside the air cylinder 10, and when no air is supplied, the operating rod 18 is automatically moved to the position shown in the figure. Performs a retraction operation.

With such a mounting structure of the eaves 3, the eaves 3 is held by the guide rollers 14 and 15 and can freely slide to the side of the vehicle body, and is also driven by the loose shaft 21 of the sliding roller 20 to slide. In the dynamic movement, i.e. in the inactive position of the cylinder 10, the eave 3 is superimposed on the roof panel 5 and the cylinder 1
In the 0 operating position, most of the eaves 3 is extended to the side of the vehicle body.

Next, the operating mechanism of the eaves 3 will be explained with reference to FIG.

In a general bus body, a door switch 26 is disposed on the operation panel 25 of the driver's seat, and when this switch is operated, the solenoid valve 28 of the drive cylinder 27 of the folding door 4 is energized, so that the power is energized through the piping 29. Dynamic pressure air is sent from the air tank 30 to the cylinder 27, thereby opening the door 4. However, in the operating mechanism of this embodiment, the middle of the piping 29 and the air cylinder 10 are connected by a branch pipe 31. With,
A blocking valve 32, a strainer 33, and a solenoid valve 34 are interposed in the middle of the branch pipe 31, and the solenoid valve 34 is connected to the door switch 260 energizing circuit 35, and the eaves switch is disposed near the door switch 26. It is connected via 36.

Therefore, if the eaves switch 36 is left open, only the door 4 will be operated by operating the door switch 26, and
When the eaves switch 36 is closed, the door 4 and the eaves 3 are operated simultaneously by operating the door switch 26.

Since the eaves device of the embodiment is configured as described above,
When the driver closes the eaves switch 36 at necessary times such as during rain or snow, the eaves 3 automatically closes the roof panel 5 in conjunction with opening (or closing) of the door 4.
This prevents passengers from getting wet, and the eaves 3 does not cause any trouble during general driving of the vehicle.

In particular, when the device malfunctions, the eaves 3 retracts due to its spring behavior, so the safety level is high.

Note that in the configuration of the embodiment, the following structure can be used in addition to the structure described above.

(a) If a rubber brim is provided on the side edge of the eaves, the effect on both pupils will be even more effective.

(b) If a guide frame for removing snow is fixed to the roof panel so as to circumscribe the side edges of the eaves, snow removal for passengers will be more effective.

(C) If a cover is fixed to the roof panel so as to cover the plywood portion exposed when the eaves are extended, the durability of the eaves device can be strengthened.

(d) In addition to the compressed air mentioned above, in-vehicle electric power or in-vehicle dynamic pressure oil may be used as the power source for moving the eaves, and a motor, piston, etc., and conventional power transmission members may be installed in the same way. effect can be obtained.

As described above, according to the vehicle eaves device according to the present invention, an eaves that can extend to the side of the vehicle body is provided on the upper surface of the roof of the door opening of the vehicle, and this eaves can be attached to the door using a simple structure called a link mechanism. Since the structure is such that the eaves are automatically extended in conjunction with This prevents passengers from getting wet during the
It has the practical effect of improving the ease of getting on and off buses, trains, etc.
