Description

[Detailed description of the invention] [Field of application of Koan] The present invention relates to a fuel gauge for automobiles.

[Background of the idea]

If the shape of the fuel tank installed in a car is, for example, a flat one with a shallow depth, the level of the fuel liquid will fluctuate due to sudden stops or cornering, etc. The indicator pointer may swing to the maximum or minimum position on the scale plate, making it impossible for the driver to confirm the correct fuel level, and sometimes causing the fuel indicator to malfunction. There were some problems, such as people sometimes misunderstanding that there was a police officer.

In order to eliminate such problems, for example, there is a fuel gauge for automobiles filed in Utility Model Application No. 165547/1983. This uses a so-called pointer type crossed coil indicator and connects an acceleration detection switch to the circuit, so that when the acceleration of the car exceeds a certain value,
The signal from the detection switch is used to cut off the signal input from the detector to the cross coil indicator, thereby making it possible to suppress fluctuations in the pointer. That is, this is shown in FIGS. 3 to 5, and 1 is an acceleration detection switch that opens when acceleration occurs.
It is connected to the resistance conversion element 3 and the power supply E. The structure of the acceleration detection switch 1 is as follows:
As shown in FIG. 5 and FIG. 5, a housing 9 in which a light emitting diode 7 and a photo sensor 8 are built is installed in a narrow manner at the lower end of a swinging arm 6 suspended from a support shaft 5 installed in a casing 4. has been done. 10 is a through hole bored in the housing 9 to allow the photo sensor 8 to receive light from the light emitting diode 7, 11 is a circuit board for driving the photo sensor 8, and 12 is a hole attached to the outer periphery of the weight 13. 14 is the cover plate, 15 is the lead wire,
Reference numeral 16 denotes a light shielding plate 1 that is formed integrally with the swing arm 6 and is provided at a position that blocks the through hole 10.
Reference numeral 7 indicates a mounting hole for the acceleration detection switch 1.

However, in such a structure, the switch 1 is screwed onto the car body through a mounting screw (not shown) passing through the mounting hole 17, so it cannot be loaded into the car. Even if the tilt angle of the vehicle body changes due to the weight of cargo and the number of passengers, or the loading position or riding position, the vehicle is used without correcting or correcting this tilt.
The sensor 1 has to detect the inclination caused by sudden stopping or cornering, along with the pre-existing inclination of the vehicle body, which poses a problem in that the accuracy of acceleration detection is reduced.

[Purpose of invention]

The present invention was developed by focusing on these conventional problems.The casing of the acceleration detection switch is pivotably supported on the vehicle body so that it can swing like a pendulum, and the swinging position of the casing can be set at any desired position. To provide a fuel gauge for an automobile, which is provided with a fixing means such as a solenoid that can be fixed in position, and by operating this fixing means, the casing can be positioned vertically when the car is started. This is the purpose.

[Example of idea]

The present invention will be explained in detail below based on the embodiment shown in FIGS. 1 and 2. The same parts between the structure of this embodiment and the structure shown in the conventional example will be referred to in the conventional example and the reference numerals will be given. The explanation of the same structural parts will be omitted. That is, this embodiment has features in the casing 21 of the acceleration detection switch 20 and the fixing means for fixing the casing 21 to the vehicle body 22, and the internal structure of the acceleration detection switch 20 is the same as that described in the conventional example. Therefore, the explanation of its internal structure will be omitted. The casing 21 has a protrusion 23 formed on its top, and a through hole 24 is bored in the protrusion 23. Further, a magnetic plate 25 formed in an arc with the through hole 24 at its center is fixed to the lower end of the back surface of the casing 21 . 26 is loosely inserted into the through hole 24 of the casing 21, and is inserted into the vehicle body 2.
2, which is a shaft screw screwed into the shaft screw 26.
The casing 21 is supported in a suspended and swingable state. 27 is a solenoid fixed to the vehicle body 22, and this solenoid is positioned so as to face the magnetic plate 25, and this solenoid 27 is used when a key is inserted into an ignition switch (not shown) and the key is turned on. When turned to the on position, it is excited and can attract and fix the magnetic plate 25.

The structure of this embodiment has been described above. Next, the operation will be described. Since the acceleration switch 20 is swingably supported by the shaft screw 26,
When the solenoid 27 is not energized, it remains blank. Therefore, with this bra attached, luggage or passengers are placed inside the vehicle, and the vehicle body 22 is thereby
Even if the acceleration switch 20 is tilted, the acceleration switch 20 will hang down due to its own weight, and the tilt of the acceleration switch will be corrected. Thereafter, when the key of the ignition switch is turned to the on position, the solenoid 27 is energized, and the magnetic plate 25 of the acceleration switch 20 is attracted, and the casing of the acceleration switch is not rocked and the vehicle body 22 is After that, the acceleration can be detected by the movement of the swing arm 6. Therefore, according to this embodiment, even if the vehicle body is tilted due to the weight of luggage, passengers, etc., the acceleration switch 20 can be automatically corrected to the hanging state, that is, the vertical state by its own weight, and when the vehicle body starts, Since the acceleration switch 20 is fixed integrally with the vehicle body, it is possible to effectively detect the acceleration of the vehicle body, and the acceleration detection accuracy can be improved. Note that a switch may be provided between the ignition switch and the solenoid 27, and the inclination of the casing 21 may be corrected as appropriate by switching this switch.

[Summary of the idea]

As described above, the present invention includes a liquid level detector 3 that emits a signal according to the liquid level as the float moves up and down, and a pointer type that is configured so that the rotation of the pointer is moderated by damper oil. Cross coil indicator 2
and an acceleration detection switch 20 which detects that acceleration exceeds a certain level and interrupts the drive signal of the pointer type crossed coil indicator 2, the top of the acceleration detection switch 20 is pivotally supported on the vehicle body so as to be able to swing like a pendulum, and is actuated by a changeover switch installed at an appropriate position on the vehicle body to detect the acceleration detection switch 20.
This fuel gauge for an automobile is characterized in that it is provided with an actuating member 27 for fixing the fuel gauge to the vehicle body.

[Effect of idea]

Therefore, according to this automobile fuel gauge, even if the vehicle body is tilted due to the weight of luggage, passengers, etc., the casing of the acceleration switch 20 can be automatically corrected to a hanging state by its own weight before driving. Since the acceleration switch 20 can be fixed to the vehicle body by operating the changeover switch, the acceleration associated with the movement of the vehicle body can be effectively detected by operating the changeover switch while the vehicle is running.
