Description

[Detailed Description of the Invention] 〓Field of Industrial Application〓 The present invention relates to a kneeling device, and more particularly to a kneeling warning device for a vehicle, which performs kneeling so that at least the vehicle height on the entrance/exit side is lowered when getting on and off.

〓Summary of the invention〓 The present invention is such that the turn signal lamp on the entrance/exit side of a vehicle equipped with a kneeling device is linked with the kneeling device, so that the turn signal lamp on the entrance/exit side is lit as a kneeling warning means when the vehicle is kneeling. By this means, during kneeling, the following vehicle is notified that the kneeling operation is in progress.

<Prior Art> In order to facilitate the operation of getting on and off a vehicle such as a bus, a kneeling device is provided to perform kneeling when getting on and off the vehicle. This type of kneeling device is linked to an air suspension device, and lowers the vehicle height at the entrance by discharging the air inside the air spring when getting on and off the vehicle. It is.

When performing this kind of kneeling motion, for example, in order to let people know,
As disclosed in Japanese Patent No. 60-8157, a kneeling indicator is provided near the entrance and exit, and this indicator is used to display kneeling.

〓Problems to be solved by the invention〓 However, since such kneeling indicators are installed on the side of the vehicle near the entrance and exit, they do not perform a kneeling motion for people getting on and off the vehicle. Although it is possible to notify the driver of a car following the kneeling motion, there is a drawback in that it is not possible to notify the driver of a vehicle following that the kneeling motion is being performed.

The present invention was developed in view of these problems, and when performing kneeling motions,
It is an object of the present invention to provide a kneeling warning device that can reliably notify the following vehicle of this, thereby ensuring safety.

〓Means for solving the problem〓 The present invention provides a vehicle that kneels to lower the vehicle height at least on the entrance/exit side when getting on or off the vehicle, and a turn signal switch and a kneeling device on the entrance/exit side of the vehicle are used. In conjunction with this, the blinker lamp on the entrance/exit side is turned on as a kneeling warning means when kneeling occurs.

〓Operation〓 Therefore, according to the present invention, when a kneeling operation is performed, the turn signal lamp on the entrance/exit side is lit at the same time, and this turn signal lamp is turned on as a kneeling warning means. Therefore, the blinker lamp can notify the following vehicle of this fact, thereby ensuring safety.

〓Example〓 The present invention will be described below with reference to an illustrated example.
1 and 2 show a bus equipped with a kneeling warning device according to an embodiment of the present invention, and this kneeling device is interlocked with an air spring of a suspension device that supports the body 11 of the bus. The vehicle body is lowered by discharging the air inside the air spring. The kneeling device 10 is connected to a transistor 12 as shown in FIG. 1, and the base of this transistor 12 is further connected to the emitter of a transistor 13. And the base of transistor 13 is AND gate 1
It is connected to output terminal 4. A kneeling switch 15 and a left turn signal switch 16 are connected to two input terminals of the AND gate 14, respectively. The turn signal switch 16 is connected to a turn signal lamp 17 attached to the rear and left side of the vehicle body 11.

In the above configuration, when the kneeling switch 15 is closed and the left turn signal switch 16 is closed, the transistor 13 is made conductive by the output of the AND gate 14, and the transistor 12 is made conductive by this transistor 13, and the kneeling switch 16 is closed. The device 10 is activated. That is, car body 1
The air in the left air spring equipped with 1 is discharged, and as a result, the vehicle body 11 changes from the state shown by the solid line to the state shown by the chain line in FIG. It will be. Since the turn signal switch 16 is closed at the same time, the left turn signal lamp 17 on the rear side of the vehicle will blink.

Therefore, according to such a device, by lowering the left side of the vehicle body 11 using the kneeling device 10 when getting on and off the bus, it becomes possible to easily and safely get on and off the bus. Moreover, when the kneeling device 10 is activated, it is possible to notify the driver of the following vehicle by the left blinker lamp 17, thereby ensuring the safety of the following vehicle. This makes it possible to provide a kneeling alarm device with higher safety. Moreover, since the kneeling warning device is also used as the left blinker lamp 17, there is no need to provide a new warning means, which is advantageous in terms of cost.

Next, a modification of the above embodiment will be explained with reference to FIG. In this modification, a turn signal switch 21 consisting of a changeover switch is connected to the battery 20, and a kneeling device 23 is connected to the turn signal switch 21 via a kneeling switch 22. Further, blinker lamps 24 and 25 are connected to the R side and L side contacts of the changeover switch 22, respectively. Therefore, by switching the winker switch 21 to the L side and closing the kneeling switch 22, the kneeling device 23 performs a kneeling operation. Moreover, at this time, since the changeover switch 21 is switched to the L side, the turn signal lamp 25 flashes to notify that the kneeling operation is being performed, and it is possible to achieve the same effect as in the above embodiment. .

〓Effects of the invention〓 As described above, the present invention links the turn signal switch on the entrance/exit side of the vehicle with the kneeling device, so that when kneeling occurs, the turn signal lamp on the entrance/exit side lights up as a kneeling warning means. Therefore, according to such a configuration, the turn signal lamp will notify you when the vehicle is kneeling, making it possible to ensure safety especially for the following vehicle.
