Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a forklift that uses LPG as fuel, and specifically relates to a fuel display device for LPG.

(Conventional technology) In a forklift that uses LPG as fuel,
Refueling is generally done by replacing the cylinders, and to simplify the replacement process, a fuel gauge for LPG is usually provided for each cylinder.

(Problem that the invention aims to solve) By the way, in the case of forklifts, the LPG cylinder is mounted at the rear of the vehicle body, so the driver has to turn around and check the remaining fuel level. It was annoying not to be able to do it.

Therefore, the technical problem to be solved by the present invention is to display the remaining amount of LPG at a position in front of the driver's seat without interfering with the cylinder replacement work. (Means for solving the problem) The technical means for solving the above problem is to install a magnet in the pointer of the gauge attached to the LPG cylinder mounted on the rear of the car body, and fix the LPG cylinder to the side of the car body. A sensor that responds to the pointer magnet was installed on the cylinder bracket to ensure this, and a fuel gauge was installed on the instrument panel in front of the driver's seat to display the remaining amount of fuel using an electric signal from the sensor.

(Function) Therefore, when the pointer of the gauge attached to the LPG cylinder rotates according to the amount of LPG in the cylinder,
A sensor on the cylinder bracket side detects the displacement of the magnet attached to the pointer, and sends an electric signal corresponding to the displacement to the fuel gauge attached to the instrument panel in front of the driver's seat, thereby controlling the amount of LPG in the cylinder. Since the amount is displayed, the driver can check the remaining amount of fuel from the driver's seat in a normal position.

(Example) Hereinafter, an example of the present invention will be specifically described based on the drawings. FIG. 1 shows the entire forklift on which an LPG cylinder 1 is mounted, and the LPG cylinder 1 is mounted on a counterweight 3 at the rear of a vehicle body 2 via a cylinder bracket 4 as shown. That is, cylinder bracket 4
has a cover 7 rotatably connected by a hinge 5 on the front side and a cover 7 connected by a tightening bolt 6 on the rear side, and the cover 7 allows the LPG
It supports cylinder 1 so as to hug it.

A float type gauge 8 is attached to the LPG cylinder 1, and the pointer 9 of the gauge 8 indicates the LPG inside the cylinder.
It is designed to be rotated in conjunction with a float 10 that moves up and down in response to the liquid level. A magnet 11 is attached to the pointer 8, and a sensor 12 (using a Hall element, for example) that changes the voltage in response to the magnet is placed on the cover 7 of the cylinder bracket 4 and faces the gauge 8. It is installed as follows. Further, a voltmeter or an ammeter as a fuel gauge 13 is provided on the instrument panel in front of the driver's seat, and the fuel gauge 13 is connected to an amplifier 14 on the way.
It is connected by a wiring 15 including. In addition,
The fuel gauge 13 is configured to display a fuel display instead of voltage or current, and the display may be digital or analog. Further, reference numeral 16 in the figure is a fixing pin for regulating the mounting orientation of the LPG cylinder 1, and although not shown, by engaging with a part of the cylinder bracket 4 or a part of the vehicle body 2, the mounting direction of the LPG cylinder 1 can be adjusted. It has come to be determined that

This embodiment is configured as described above,
Therefore, when the pointer 9 of the gauge 8 of the LPG cylinder 1 is rotated via the float 10 to a position corresponding to the amount of LPG in the cylinder, the sensor 12 that is sensitive to the magnet 11 attached to the pointer 9 moves to the position corresponding to the amount of LPG in the cylinder. A voltage corresponding to the position of the magnet 11 is outputted to the fuel gauge 13 via the amplifier 14, and the fuel gauge 13 digitally or analogously measures the remaining amount of fuel in the LPG cylinder 1 according to the output voltage. indicate. Therefore, the driver can check the remaining amount of fuel in the driver's seat in a normal posture. Note that the replacement of the LPG cylinder 1 is performed after releasing the restraint by the cover 7, but since the sensor 12 is installed on the cover 7 side, the replacement work is necessary due to the fuel display being changed to the driver's seat side. The cylinder replacement work can be carried out as easily as before without causing the above disadvantages.

(Effect of the invention) As described above, according to the invention, the rear part of the vehicle body
For forklifts equipped with LPG cylinders, the driver can check the remaining fuel level from the driver's seat in a normal position, which is extremely effective in improving work safety and efficiency. Moreover, by providing the sensor on the cylinder bracket side, the LPG cylinder replacement work for refueling can be performed in the same way as before without any trouble.
