Vehicle digital display fuel level indicator {automotive fuel detecting gaugeunit digital dispiay system}

The present invention relates to a digital display fuel remaining amount display device provided in a vehicle, and in particular, a fixed thermistor is separately provided at a predetermined bottom side of the fuel tank for a vehicle to accurately measure the fuel remaining in the fuel tank for the vehicle. The present invention relates to a digital display type fuel level indicator for a vehicle that allows a driver of a vehicle to more accurately grasp a fuel level by displaying it through a digital display provided at one side of an instrument panel.

In general, thermistors are semiconductor thermosensitive devices made by mixing oxides with nickel, cobalt, and manganese properly, followed by sintering with a binder at a high temperature of about 1000 ° C or higher. It has the property that resistance value becomes small by magnetic heating when it flows, and property that resistance value changes with time by magnetic heating when current flows.

These thermistors are used in automotive electronics and used in units of water temperature gauges, water temperature sensors, etc. The thermistor elements are negative and positive in temperature coefficients of resistance. This is used to detect the residual amount of.

1 is a view schematically illustrating the main components of a general fuel residual amount display device for a vehicle, and a conventional fuel residual amount display device for a vehicle includes a float 2 floating or floating according to the amount of fuel injected into a vehicle fuel tank 1; It consists of a variable thermistor 3 whose resistance value changes with the degree of swelling of the knitting 2, and a fuel residual amount display gauge 4 for displaying the current fuel residual amount according to the change of the resistance value.

When the driver of the vehicle wants to check the amount of fuel remaining in the fuel tank 1 by the conventional general vehicle fuel remaining amount display device configured as described above, the fuel residual gauge 4 provided at one side of the vehicle instrument panel is provided. It can be seen that the fuel remaining gauge (4) operates with the following mechanism.

That is, the inside of the fuel tank (1) is provided with a float 2 and a variable thermistor (3), which is a device indicating the residual amount of fuel when the fuel is injected, first, the float 2 is the fuel tank (1) As the height of the fuel in the vessel decreases, the variable thermistor 3 changes its resistance value as the float 2 floats or sinks, and the current fuel level is measured.

In addition, as the variable thermistor 3 changes, the fuel remaining amount indicator gauge 4 provided at one side of the vehicle instrument panel 5 indicates the current fuel residual amount.

However, such a conventional fuel remaining fuel display device for vehicles, as the fuel of the vehicle is consumed, the float 2 floating in the fuel tank 1 is buried only to a certain height from the bottom of the fuel tank 1 so that the fuel quantity shortage is at the reference limit. In this case, only the warning light is turned on in the fuel remaining amount indicator gauge 4, so that the driver of the vehicle does not grasp the quantitative fuel remaining amount.

Accordingly, the present invention has been made to solve the fundamental problems of the prior art as described above, the object of which is to present the remaining fuel level of the vehicle driver by accurately measuring and digitally displaying the remaining amount of fuel in the fuel tank of the vehicle To provide a vehicle digital display fuel level indicator that can accurately check the status.

As can be seen from the above, the present invention provides a float that floats or sinks according to the amount of fuel injected into the vehicle fuel tank 1, a variable thermistor whose resistance value changes according to the degree of the float, and the resistance of the variable thermistor. A fuel level indicator for a vehicle having a fuel level indication gauge in which a current fuel level is displayed by a value,

A fixed thermistor 6 provided at a predetermined portion of the bottom side of the fuel tank 1 so as to accurately detect the remaining amount of fuel remaining in the fuel tank 1 and detected from the fixed thermistor 6; The display driver 7 converts a resistance value into a fuel residual amount and converts the value into a digital value, and receives a digital signal from the display driver 7 to display a current fuel residual value of the vehicle instrument panel (not shown). It is composed of a digital display 8 provided at one side of a predetermined portion.

Vehicle digital display fuel residual amount display device of the present invention having the configuration as described above will be described as follows in more detail with reference to the accompanying drawings.

In general, in the case where the remaining amount of fuel remaining in the vehicle fuel tank 1 is to be quantitatively known, the digital display type fuel residual amount display device for the vehicle according to the present invention is applied to the fuel in the vehicle fuel tank 1 first. When is reached to the ground state is connected to the float floating or buried according to the amount of fuel injected into the fuel tank (1) because only the variable thermistor whose resistance value changes depending on the degree of the float can not accurately measure the remaining fuel The fixed thermistor 6 is provided on the bottom side small portion of the fuel tank 1, and the fixed thermistor 6 is provided. The amount of fuel remaining through the fixed thermistor 6 can be more accurately measured. Will be.

In addition, when the fuel residual amount in the fuel tank 1 is measured by the fixed thermistor 6 as a resistance value, the display driver 7 converts the resistance value detected from the fixed thermistor 6 into a fuel residual amount. Will be transcoded into a value.

In addition, the fuel residual amount measurement value converted into a digital value by the display driver 7 is output through the digital display 8 provided at one side of the vehicle instrument panel (not shown).

Here, the fixed thermistor 6 provided on the inner bottom side of the fuel tank 1 is operated to detect the remaining amount of fuel when the fixed thermistor 6 is lower than a certain amount of fuel in the tank to output a predetermined electrical signal.

First, when the fuel tank 1 is filled with fuel, the fixed thermistor 6 detects fuel because the fixed thermistor 6 that detects the fuel is in a submerged state below the liquid oil level. The temperature is lowered and the temperature is lowered, so the resistance value of the fixed thermistor 6 is large, and thus an electrical signal is not output. Thus, the stationary state of the fixed thermistor 6 is air. Since the fixed thermistor 6 generates heat, the temperature rises, the resistance of the fixed thermistor 6 decreases, and a current flows in the circuit to output an electric signal. A predetermined signal is input to the digital display 8 so that the driver can be easily judged so that the remaining fuel amount in the fuel tank 1 can be accurately identified.

As described above, the vehicle digital display fuel residual amount display device according to the present invention includes a digital display 8 at one side of the vehicle instrument panel 5, and at the bottom side of the fuel tank 1.
