Description

Automobile mounted Fuel-filling metering device

One, technical field

The utility model relates to the liquid volume measurement device, the gasoline measuring apparatus of using for the consumer during especially for automobile fuel filler.

Two, background technology

The present domestic automobile mounted Fuel-filling metering device of not finding as yet.Generally the metering to volume read-out is (the national regulation precision is 0.3%) of leaning on the degree of accuracy of fuel charger to ensure, but, there are many refuelling stations to use high-tech means at present, can be under the prerequisite of the measuring accuracy of not damaging fuel charger, the control chip of fuel charger is made coefficient of flow (pulse equivalency) revise, steal oil.Its means are hidden, are difficult to find.

Three, utility model content

Task of the present utility model is to provide a kind of automobile mounted Fuel-filling metering device, with help scene, consumption side check added the oil mass of fuel tank.This task is realized by following design: a kind of automobile mounted Fuel-filling metering device, comprise automotive oil tank, single-chip microcomputer, monolithic processor controlled display driver circuit and nixie display, also has measuring container: oil filler is arranged on it, its underpart has a lower end to stretch into the interior outlet tube coupling of automotive oil tank, on the outlet tube coupling outlet valve by monolithic processor controlled time-delay closing is arranged; Comprise also being used for determining oiling beginning and the oil-feed sensor of termination time that it is arranged near the fluid passage of oil filler; Also Bao Shi is arranged on the measuring container, is used to determine to refuel to the fuel level sensor of used time of predetermined fluid level of measuring container; The output signal of above-mentioned oil-feed sensor and fuel level sensor is connected to described single-chip microcomputer respective input.In the above-mentioned design, locate to be provided with a measuring container (promptly when reaching predetermined oil level, institute's volume read-out is a known volume, and in other words, when reaching predetermined oil level, the volume of container correspondence is a known mensuration number) at automotive oil tank (on the fuel tank or in the fuel tank).When refueling, fluid at first enters measuring container through oil filler, at this moment, oil-feed sensor action, send signal and pick up counting to single-chip microcomputer, when oil mass reaches predetermined oil level, fuel level sensor action, send signal to single-chip microcomputer, single-chip microcomputer according to refuel to predetermined oil level be predetermined and whole process institute consumption time, calculate fluid flow (as rise/minute).In the above-mentioned flow measurement process, the outlet valve of measuring container bottom cuts out.When above-mentioned fuel level sensor moved, single-chip microcomputer sends signal opened the outlet valve of measuring container, and fluid is flowed among the fuel tank, at this moment, refueling process is still underway, and is last, when refueling end, the flow of oil-feed sensor of flowing through is zero, the oil-feed sensor sends signal to monolithic, and single-chip microcomputer is according to oiling start time and termination time, and the flow of measuring, calculate the numerical value of institute's volume read-out, and on display, intuitively show.At this moment, outlet valve is subjected to time-delay control, still is opening, and after with the fluid emptying in the measuring container, row is closed again, and when refueling in order to next time, the sky that measuring container is in no remaining fluid holds situation.This novel measuring container (volumetric standard) mensuration that utilizes, can be in certain accuracy rating (as 1%), the car owner is checked volume read-out, can safeguard that like this car owner's legitimate interests and strike steal oily behavior, and avoid state tax revenue loss (at following economic relation: after the road toll expense will be collected taxes from now on, and be embodied among the gas price).

Fig. 3 is the synoptic diagram of an embodiment of fuel level sensor shown in Figure 1

Five, embodiment

Among Fig. 1, measuring container 2 is arranged in the automotive oil tank 1, and the oil filler of automotive oil tank 1 is the oil filler 2a of measuring container.A bite tube coupling 8 is arranged at measuring container 2 bottoms, has one by monolithic processor controlled time-delay closing outlet valve 6 on the outlet tube coupling 8.Usually, measuring container 2 also can be arranged on the automotive oil tank, and the oil filler that the oil filler 2a on the measuring container 2 replaces automotive oil tank uses as adding the oil-in, just requires the lower end of the outlet tube coupling of measuring container bottom to stretch in the automotive oil tank.Oil-feed sensor 3 is arranged near the fluid passage of oil filler, is used for determining to refuel beginning and termination time.Fuel level sensor 4 is arranged on the measuring container 2, is used to determine to refuel to the used time of the predetermined of measuring container.The output signal of oil-feed sensor 3 and fuel level sensor 4 is connected to the single-chip microcomputer order and answers input end.Referring to Fig. 2, oil-feed sensor 3 is constructed as follows: deflecting plate 9 is arranged near the fluid passage of oil filler 2a, and hinged with plate washer 12 through pin joint 7, the left and right side of plate washer 12 (for Fig. 2) is equipped with a luminous second tube sheet 10 (or being general electron luminescence device) and photoelectric tube 11 (whole effect is equivalent to the optoelectronic switch by flow control) respectively.Referring to Fig. 3, fuel level sensor is constructed as follows: L-shaped connecting pipe 15 1 ends stretch in the measuring container 2, the other end is positioned at outside the measuring container wall, is respectively arranged with light emitting diode 16 and photoelectric tube 13 on the height and position of left and right (for Fig. 3) both sides corresponding to the predetermined fluid level 14 of measuring container 2.The output signal of photoelectric tube 13 is connected to the single-chip microcomputer respective input.As shown in Figure 1, can on automotive oil tank 1, one protective cover 5 be set the position corresponding to measuring container 2, single-chip microcomputer and peripheral circuit (electronic devices and components that comprise above-mentioned oil-feed sensor and fuel level sensor) thereof can be placed in it.This novel course of work is as follows: when refueling beginning, the fluid deflecting plate 9 of flowing through, deflecting plate 9 together is offset along pin joint 7 with plate washer 12, plate washer 12 offsets (i.e. skew forward among Fig. 2), photoelectric tube 11 obtains illumination and conducting, the output signal of photoelectric tube 11 is connected to the single-chip microcomputer respective input, and single-chip microcomputer picks up counting to oiling.When fluid reaches predetermined fluid level 14 in the measuring container, fluid has stopped the light of light emitting diode 16 to photoelectric tube 13 emissions, photoelectric tube 13 outputs signal to single-chip microcomputer, single-chip microcomputer calculates from beginning to refuel to and refuels to predetermined (volume when fluid reaches predetermined fluid level measuring container) the used time, calculates the volumetric flow rate of fluid when refueling again according to time and volumescope.When photoelectric tube 13 outputed signal to single-chip microcomputer, single-chip microcomputer sent signal, and control outlet valve 6 is opened, and enters in the automotive oil tank in the fluid people measuring container.When stopping to refuel at last, the fluid flow is zero, plate washer returns to the original position from the skew situation, promptly block the light of light emitting diode 10, photoelectric tube 11 exports the signal that obtains to single-chip microcomputer, and single-chip microcomputer calculates whole refueling time, again according to the volumetric flow rate that calculates, calculate the total oil mass that adds in the automotive oil tank, on nixie display, show.Outlet valve 6, is prepared against when refueling with the fluid in the emptying measuring container stopping to refuel the back time-delay closing next time, correctly repeats above-mentioned metering process.
