Abstract
The utility model provides a device for displaying the fuel quantity of an automobile oil tank, comprising a Hall circuit, wherein, an input end of the Hall circuit is connected with a voltage stabilizing circuit and an output end of the Hall circuit is connected with an amplifying circuit; an input end of the voltage stabilizing circuit is connected with a current index gauge; and an input end of the amplifying circuit is connected with the voltage stabilizing circuit and the current index gauge. The device for displaying the fuel quantity of the automobile oil tank adopts a Hall element to measure the magnetic field displacement in fuel, outputs corresponding varying voltage and working current, has the fuel quantity display precision higher than that of the prior domestic automobile fuel indicator, and has long service life.
Description
Technical field
The utility model relates to a kind of automotive oil tank amount of fuel display device.
Background technology
At present, the most fuel display systems that adopt variable resistance type of domestic automobile, for example liberate automobiles such as 141,151 automobiles, popular general mulberry, exist rubbing contact, wearing and tearing are arranged, serviceable life is short, and working current is big, measuring accuracy is not high, just general expression Fuel Oil Remaining, and Dongfeng Automobile 140 also adopts essentially identical fuel display system.
Above old product was produced in for 19th century, differed greatly with the requirement of existing user vehicle, and it is short to exist serviceable life, general 1-2 will safeguard and change, and is that specially table is special-purpose, can not exchange, especially can not satisfy modern society's demand, managing with automobile computer can not be compatible.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of measuring accuracy height is provided, the automotive oil tank amount of fuel display device of long service life.
To achieve these goals, the technical solution adopted in the utility model is: a kind of automotive oil tank amount of fuel display device, it is characterized in that it comprises Hall circuit, described Hall circuit input termination mu balanced circuit, its output termination amplifying circuit, mu balanced circuit input termination electric current indicating gauge, input amplifier is connected to mu balanced circuit and electric current indicating gauge.
The utility model compared with prior art has the following advantages:
1, can in inflammable and explosive environment, use.
2, the contact wear that does not have original resistive amount of fuel to show, the reliability height.
3, working current is little, saves limited automobile power source energy.
4, easily install and transform.
The fundamental measurement that 5, can adapt to other liquid.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
A kind of automotive oil tank amount of fuel display device shown in Figure 1, it comprises Hall circuit 1, described Hall circuit 1 input termination mu balanced circuit 3, its output termination amplifying circuit 2, mu balanced circuit 3 input termination electric current indicating gauges 4, amplifying circuit 2 input ends are connected to mu balanced circuit 3 and electric current indicating gauge 4.
As depicted in figs. 1 and 2, when the automotive oil tank fuel change, cursory along with moving up and down, cursory axle is subjected to displacement with the magnet at place, Hall circuit 1 produces small output voltage to be changed, make triode BG1 conducting through adjustable resistance R2, electric current indicating gauge 4 shows that producing small electric current exports, expression fuel tank fuel change.
When automotive oil tank fuel did not change, cursory motionless, cursory axle was not subjected to displacement with place's magnet, and the instrument demonstration remains unchanged.
Voltage stabilizing element U1 in the circuit changes to 5V with voltage 12V, and the operating voltage of Hall element CS is provided, and load current is provided for Hall circuit 1 through resistance R 1, and capacitor C 1 and C2 are filter capacitors.
