Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is further described.
Incorporated by reference to reference Fig. 1-3, the embodiment of the present invention provides a kind of headlight for vehicles mechanism with an automatic light meter, including light shaft offset
Detection device 1, the car body control module 2 being connect with light shaft offset detection device 1 and the driving being connect with car body control module 2 dress
3 are set, driving device 3 is connect with the front lens 42 of headlight for vehicles 4.
Light shaft offset detection device 1 is for measuring the intensity of illumination Distribution Value of headlight for vehicles 4 and according to the light of headlight for vehicles 4
The offset of 4 primary optical axis of headlight for vehicles is judged according to intensity distribution value and generates corresponding shifted signal simultaneously.
Car body control module 2 is used to receive the shifted signal of the sending of light shaft offset detection device 1 and exports corresponding control
The front lens for the control signal adjustment headlight for vehicles 4 that signal is issued to driving device 3, driving device 3 according to car body control module 2
42 installation site makes the main shaft of front lens 42 and the central axis of light source 44 be located along the same line.
In the present embodiment, light shaft offset detection device 1 includes 11, four light sensitive components 12 of light-receiving case and luminous intensity point
Cloth analysis module 13.Wherein, the front end of light-receiving case 11 with 4 face of headlight for vehicles so that the light that headlight for vehicles 4 issues passes through,
The front end center line and the central axis of light source 44 of light-receiving case 11 are located along the same line.Four light sensitive components 12 are set to light
The front end of receiving magazine 11 deviates from the side of headlight for vehicles 4, and square arrangement constitutes a four-quadrant photosensitive system, this four
The central axis of quadrant photosensitive system and the center line of the front end of light-receiving case 11 are located along the same line.Light intensity distributions analysis
Module 13 judges offset and the generation of 4 primary optical axis of headlight for vehicles according to the illumination intensity value that four light sensitive components 12 receive
Corresponding shifted signal.It should be noted that the light beam on the central axis of non-light source 44 is after the diverging of front lens 42, intensity becomes
It is very weak, the light of this part substantially will not the intensity of illumination that senses of four light sensitive components 12, in other words, that is, four light
The intensity of illumination that sensing unit 12 senses is the light beam on the central axis from light source 44.

When intensity value maximum, light intensity distributions analysis module 13 can judge 4 primary optical axis of headlight for vehicles to left upper quadrant offset and it is same
Shi Shengcheng left-hand shifted signal is to car body control module 2, it is of course possible to understanding, the at this time front lens 42 of headlight for vehicles 4
Main shaft is deviated to upper left.Car body control module 2 issues corresponding control signal control after receiving corresponding shifted signal and drives
Dynamic 3 actuation of device makes driving device 3 adjust the position of front lens 42 so that the main shaft of front lens 42 and the center of light source 44
Line is located along the same line.Specifically, when the main shaft of the front lens 42 of headlight for vehicles 4 is deviated to upper left, car body control module 2
The control signal control driving device 3 of output drives the lower adjustment to the right of front lens 42.
When to collect illumination intensity value identical for upper left light sensitive component 12 and lower-left light sensitive component 12, upper right light sensitive component 12 with
The collected illumination intensity value of bottom right light sensitive component 12 is identical, and when upper left light sensitive component 12 and lower-left light sensitive component 12 acquire
It is greater than upper right light sensitive component 12 and the collected illumination intensity value of bottom right light sensitive component 12, this Light intensity point to illumination intensity value
Cloth analysis module 13 can judge that 4 primary optical axis of headlight for vehicles deviates to the left and exports 4 primary optical axis of headlight for vehicles and deviate letter to the left
Number to car body control module 2, the control signal control driving device 3 that car body control module 2 exports drives front lens 42 to adjust to the right
It is whole.It is understood that light intensity distributions analysis module 13 judges that 4 primary optical axis of headlight for vehicles deviates to the right, downward or upward
Principle it is identical as the principle for judging that 4 primary optical axis of headlight for vehicles deviates to the left, car body control module 2 export control signal control
Before the control signal control driving of driving device 3 that driving device 3 adjusts 42 position principle of front lens and car body control module 2 exports
The principle that lens 42 adjust to the right is also identical, and details are not described herein.
In the present embodiment, light sensitive component 12 is photocell, and light sensitive component 12 is used to collected illumination being converted into electricity
Stream, in other words, that is, the photocurrent values that light sensitive component 12 generates represent the collected illumination intensity value of light sensitive component 12,
Correspondingly, light intensity distributions analysis module 13 judges headlight for vehicles by judging the photocurrent values that four light sensitive components 12 generate
The offset of 4 primary optical axis.
