Description
The utility model relates to a kind of store oil and measures quantity display apparatus, and particularly a kind of electronic type store oil measures quantity display apparatus.This device is applicable to motor vehicle, ship and is that the measurement of the engine oil tank store oil amount of power shows with the internal combustion engine.
The utility model improves on original patented technology (patent No. 86 2 05729.9) basis and gets, and is a kind of modified electronic type store oil quantity display apparatus.
Existing motor vehicle, ship and be that the engine oil tank store oil measuring device of power has four classes with the internal combustion engine, this four class can be summed up as two kinds again, i.e. electromagnetic type and electrothermal.These two kinds of devices are pointer-type, promptly with needle deflection indication oil mass.Because constantly vibrations in continuous vibration and car or the foot process in the engine working process, constantly fluctuation also takes place in the pasta in the oil tank thereupon, it is corresponding unsteady that this fluctuation makes that the ball float of pasta follows suit, and this floating of ball float makes the slide of connecting rod constantly be subjected to displacement on resistor again; The working current of these two kinds of devices is at 0.1～0.15A in addition, and the electric current of flows through sensor is also at 0.1～0.15A, like this with regard to making on the resistor tiny resistance wire be easy to by this wearing and tearing and heating and burn; Because the continuous vibration of car, ship and engine, armature spindle and the pointer in the dial plate all is damaged, is out of shape or block motionless easily, thereby had a strong impact on accuracy, reliability and the durability of store oil measurement amount; Pointer indicating graduation is narrow simultaneously, so the oil mass indication is not directly perceived, not eye-catching, especially more outstanding at driving at night.
Original patented technology also is made up of electronic circuit and sensor two parts, adopt light emitting diode intuitively to show, but gauge outfit and sensor extension line is more, and every demonstration one scale just must be drawn a branch road, and can only show by single lamp.
The purpose of this utility model is to improve existing store oil to measure quantity display apparatus and electronic type store oil measurement quantity display apparatus, and the electronic type store oil that provides a kind of full-electronic components and parts to constitute measures quantity display apparatus.This device vibration resistance, long-life, reliable operation, no matter oil mass shows in the daytime or night is all clear, bright, accurately, sound and light alarm during low oil level does not have and does not cut off the electricity supply automatically when oily.
Electronic type store oil of the present utility model measures quantity display apparatus and is made up of two parts.First is the electronic circuit part, is made up of shared current-limiting resistance (1), diode (2), current-limiting resistance (3), display device (4), warning branch road (5); Second portion is a sensor, is made up of divider resistance and diode (9), contact block (11), slider (10), pitman shaft (12), connecting rod (13), ball float (14).When the ball float on the sensor contacts with contact block by the slider on the connecting rod, change corresponding sensor with oil level and be connected with resistance and diode, this resistance partly is connected with electronic circuit with diode; Oil level variable signal on the sensor is become electric signal, again electric signal is become light signal, display device is shown in the mode of light.According to the luminance of display device and the number of light emitting diode, just can record what of store oil amount.Measuring quantity display apparatus with existing pointer-type and electronic type store oil compares, the utility model has the advantages that: simple in structure, easy to maintenance, low cost of manufacture, few, cheap, the intuitive display of consumption material, accuracy, reliability and durability are strong simultaneously.This device can be designed to the fuel level gauge that matches with the oil tank of different model thereby highly versatile.
Below in conjunction with accompanying drawing embodiment is described in further detail:
Figure (1) is a fundamental diagram of the present utility model.
Figure (2) is the Pareto diagram of light emitting diode on dial plate.
From figure (1) as seen: electronic type store oil of the present utility model measures quantity display apparatus and is made up of electronic circuit and sensor two parts, wherein electronic circuit partly is installed in the watchcase of gauge outfit (1) of figure (2), and with lead gauge outfit (1) and sensor (5) is interconnected (see figure 2).
Figure (1) is the fundamental diagram of this device.By the shared current-limiting resistance (1) among the figure (1), diode (2), current-limiting resistance (3), display device (4) and warning branch road (5) constitute electronic circuit; Constitute sensor by the diode among the figure (1) and resistance (9), contact block (11), slider (10), pitman shaft (12), connecting rod (13), ball float (14).The fuel tank (16) among the figure (1) and the oil level (15) of fuel tank are in order to describe the optional feature of the utility model embodiment.
By figure (1) as seen: ball float (14) is subjected to the control of the oil level (15) of fuel tank, drivening rod (13) rotates around pitman shaft (12), make slider (10) on contact block (11), do the contact circular motion, thereby make the electronic circuit of this device constitute the closed-loop path.When expiring oil level, slider (10) slides to α contact block (11), and display device (4) is bright entirely; When oil level changed from high to low, slider (10) slided to b, c, d contact block (11) respectively, and display device (4) is by only extinguishing, according to the just oil mass in the fuel tank as can be known of the luminous number of display device.When the oil level continuation reduction of fuel tank, ball float (14) drivening rod (13) rotates around pitman shaft (12), when making slider (10) slide to e contact block (11), connect the warning branch road, red light emitting diodes flashes, and buzzer sends alarm sound, plays the sound and light alarm effect; When oil was intact, ball float (14) drivening rod (13) rotated around pitman shaft (12), makes slider (10) slide to the f position, and all loops disconnect, and no current flows through in the circuit, and extinguish full display device (4), (6).
By figure (1) as seen: slider (10) respectively with a, b, c, d contact block (11) when contacting, sensor inserts the diode of different numbers and the resistance of different resistances respectively, make the electric current that flows through electronic circuit be reduced to 5～6mA from 30mA, (8) the some current potential improves, and just can control the luminous number of display device (4); Change the resistance of resistance (1), the number of diode (2), sensor resistance resistance and number of diodes (9), contact block (11) number just can change the number of the light emitting diode of display device (4): the resistance that changes resistance (3) can change the brightness of light emitting diode (4).
By figure (1) as seen: slider (10) and e contact block (11) are when contacting, warning branch road (5) constitutes the closed-loop path with common source, capacitor C 1 charging, when capacitor C 1 two ends charging voltage reaches the honeybee threshold voltage of unijunction transistor BG, unijunction transistor BG conducting, light emitting diode this moment (6) is luminous, and buzzer (7) sends the sound; Capacitor C 1 by the R2 discharge, is recharged again after having discharged again simultaneously, goes round and begins again like this, has just formed the flash of light of light emitting diode (6) and the sound at intermittence of buzzer (7), plays the sound and light alarm effect.
Present embodiment can adopt the light emitting diode of different colours so that reach the purpose of demonstration fuel tank store oil amount directly perceived.
