Brief description of the drawings
Fig. 1 is the structural representation of utility model works state；
A represents the front portion of vehicle frame in figure.
Embodiment
Referring to the drawings, a kind of automatic tester for vehicle headlamp, a kind of automatic tester for vehicle headlamp, including light-receiving case 10, and
At least three retractable support frame 11 is set on the control cabinet set on light-receiving case 10, described light-receiving case 10, branch of stretching
It is anterior that support 11 is fixed on vehicle frame；
Lens subassembly 12, photocell 13, photo resistance plate 14, light detection are disposed with light-receiving case 10 from front to back
Device 15；
Microprocessor controller 20, photoelectric sensor 30, relay 40, amplifier 80, displacement are set in described control cabinet
Sensor 90, potentiometer 50, Operation switch 60, display screen 70；
Described light-receiving case 10 is electrically connected with described control cabinet.
Further, described photocell 13, photo resistance plate 14 are located at the upper and lower, left and right position pair of light-receiving case 10
Claim to set four.
Further, 3 retractable support framves 11 are set on light-receiving case 10, and retractable support frame 11 is set positioned at vehicle frame front portion
Put sucker.
It is preferred that, described potentiometer 50 includes zero-bit and adjusts potentiometer 51 and gain-adjusted potentiometer 52.
Structural principle of the present utility model：Light-receiving case 10 is fixed on the front portion of vehicle frame by 3 retractable support framves 11,
The transmitting of light-receiving case 10 laser beam finds vehicle car light center line and horizontal line accurately, and detecting instrument starts after level is determined.In light
Lens subassembly 12, photocell 13, photo resistance plate 14, optical detection device 15 are disposed with inside receiving magazine 10 from front to back.
Wherein, the upper and lower, left and right positional symmetry of light-receiving case 10 sets four photocells 13 and photo resistance plate 14, is chased after as optical axis
Track.When illuminance that upper and lower photocell 13 is subject to is different, the offset signal transmission of generation to microprocessor controller 20.Equally,
The deviation signal of left and right photocell 13 can be also transmitted to microprocessor controller 20, record optical axis four-way position error signal.Lens
Photo resistance plate 14 behind component 12, is detected as optical axis deviation.After headlight beam is by 12 optically focused of lens subassembly, shine
Penetrate at the center of the electro-optical package 13 matched with each photo resistance plate 14, photoelectric sensor 30 produce voltage drop, gained it is inclined
Difference signal is zero (upper and lower table and left and right table on display screen 70 are designated as zero).If instrument is positioned at key light shaft position
When, by the BEAM SQUINT center of the lens subassembly 12 of optically focused, deviation signal will necessarily be produced.Microprocessor controller 20
Deviation signal, the downward shift deviation signal offset according to left and right, calculates luminous point above and below, the indexing of vertical direction distance center
Value, and intuitively it is shown in display screen 70 up, and simultaneous display is showing after the processing of luminous point deviation adjustment scheme censorship slowdown monitoring circuit
On display screen curtain 70.
In addition, for the ease of manually adjust operation and calibration etc., instrument be also equipped with correlation relay 40, amplifier 80,
Potentiometer 50, displacement transducer 90, Operation switch 60.Instrument is adjusted and two potentiometers of gain-adjusted 51,52 equipped with zero-bit, by
Directly affect positioning precision in zero drift, and gain it is too small can lowering apparatus detection sensitivity, cause zero point error to increase,
But the too high stability that can make instrument of gain is reduced.The zero-bit adjustment potentiometer 51 and gain-adjusted potentiometer 52 of setting ensure instrument
Device system accuracy.Under condition determination, relay 40 is turned on, and the signal of photocell 13 is accessed amplifier by its normally opened contact
80, and adjust its equalization point with potentiometer 50.In calibration (calibration lamp luminous intensity 20000cd), optic angle is put for 0 °, regulation
It is zero to make corresponding optic angle indicating gage reading.When exiting measure, its normally opened contact release of relay 40, its normally-closed contact difference
Potentiometer 50 and displacement transducer 90 are connected, if now lens are not in origin, microprocessor controller 20 provides degree of bias value and letter
Single adjustment direction.
Detector measures the luminous intensity and optic angle of headlamp using same group of photocell 13.So the signal of photocell 13
In addition to being sent to optic angle measuring circuit, also give add circuit and carry out Signal averaging, to produce the signal of luminous intensity.It is luminous
Strength signal and optical axis angle signal are sent to respective indicating gage circuit simultaneously, and each digital indicator circuit is equipped with regulation electricity
Position device 50, for adjusting gain, the zero point of amplifier 80 and the scale value for calibrating indication electric meter of circuit.For the ease of microprocessor
Controller 20 is handled, and these signals are also exported as sampled signal, is connected by connection cable with microprocessor controller 20.
The machine constitutes the front portion that gusseted is fixed on vehicle frame, volume using 3 retractable support framves 11 with sucker
Small, lightweight, convenient handling.Light flow is gathered using photoelectric sensor 30, display screen 70 is intuitively shown.Carry laser hair
Source and pip are penetrated, the solid detection position in vehicle frame of laser reflection point letter can rapidly and accurately make instrument be directed at headlamp
Primary optical axis.Detect during use, pass through the centre bit of auxiliary positioning promise instrument.Because traditional approach is broken away from operation,
So occupy little space, in addition to the rest configu no requirement (NR) of car body, no matter slope, meadow, on one side it is high it is low on one side do not affect,
As long as maintenance personal can conveniently work.
