Abstract

The utility model discloses a dizziness proof device for detecting head lights of a car, composed of a base (1), a vertical column (2), a rotating and supporting bracket (3) and an optical detecting box (4). Quantitative data and figures for computer analysis can be conveniently obtained through lens, a half-reflecting mirror, an image pickup device, a screen plate, a back photoelectric detector and a front photoelectric detector in the optical detecting box (4). Therefore, that the beams of the passing light of a car are consistent with the national standards or not can be evaluated accurately.

Description

Anti-glare vehicle headlamp pick-up unit

The utility model relates to a kind of anti-glare vehicle headlamp pick-up unit.

At present, in order to guarantee the safety of driving at night, all motor vehicles all are equipped with the headlamp that night illumination is used, and the headlamp emitted light beams is divided into two kinds of driving beam and passing beams.The road lighting of fast running when driving beam is used to not have the other side to send a car, its light beam are symmetrical expression and distribute.Road lighting when the dipped beam light velocity is used for meeting produces and to dazzle the eyes send a car driver's eyes of the other side in order to prevent headlight beam, and the regulation of national standard to passing beam arranged.The full-automatic headlamp aligner that uses on the existing information of safety inspection for motor vehicles station, can only the driving beam that be symmetrically distributed be detected, detection for asymmetrical passing beam, can only pass through the type hand headlamp aligner, the direction of illumination of passing beam, this detection method are roughly judged in detect by an unaided eye on the small screen that instrument the was equipped with distribution pattern and the position of tested headlamp, the human factor influence is serious, and this just brings the accuracy of detection not high.

The purpose of this utility model is to provide the anti-glare vehicle headlamp pick-up unit of the high detection by quantitative passing beam of a kind of accuracy.

For achieving the above object, anti-glare vehicle headlamp pick-up unit of the present utility model is made up of base, column, swinging mounting, light detection case, between column and the base for fixedlying connected, be flexible connection between swinging mounting and the column, the light detection case is installed on the swinging mounting, is provided with lens, half-reflecting mirror, image pick-up device, screen board in the light detection case; Lens are arranged on the position in light detection case front; Screen board is located on the position at the back side of visual plate; Half-reflecting mirror is located at the light that lens are seen through and is reflected in the case on the screen board on the position; Image pick-up device is located on the position that can absorb the image on the screen board.

After adopting such structure, because half-reflecting mirror in the light detection case is located at the light that lens are seen through and is reflected in the case on the screen board on the position, be sent to computing machine after just the light distribution pattern of the headlamp on the screen board can being obtained by image pick-up device, go out this light beam and whether meet the requirements thereby reach detection by quantitative.

Fig. 1 is the structural representation of specific embodiments of the present utility model.

Fig. 2 is the structural representation of smooth detection case of the present utility model.

Anti-glare vehicle headlamp pick-up unit of the present utility model as shown in Figure 1 and Figure 2 is made up of base 1, column 2, swinging mounting 3, light detection case 4, between column 2 and the base 1 for fixedlying connected, be dynamically connected for words between swinging mounting 3 and the column 2, light detection case 4 is installed on the swinging mounting 3, is provided with lens 6, half-reflecting mirror 7, image pick-up device 8, screen board 10, rearmounted photoelectric detector 9, preposition photoelectric detector 11 in the light detection case; Lens 6 are arranged on the position in light detection case 4 fronts; Preposition photoelectric detector 11, screen are put plate 10 and are located at respectively on the position at the back side of visual plate 5; Half-reflecting mirror 7 is located at the light that lens 6 are seen through and is reflected in the case on the screen board 10 on the position; Rearmounted photoelectric detector 9 is located at and can receives half-reflecting mirror 7 through on the position of light; Image pick-up device 8 is located on the position that can absorb the image on the screen board 10.During detection, adjust the axis of auto lamp light beam and light detection case earlier with the high beam light beam, during adjustment, driving beam enters light detection case 4 after lens 6 are assembled, be two parts in half-reflecting mirror 7 punishment, a part is passed half-reflecting mirror and is arrived rearmounted photoelectric detector 9, therefore another part reflexes on the screen board 10, and screen board 10 light transmissive material manufacturing can receive above-mentioned reflected light at thereafter preposition photoelectric detector 11.Whether can measure light detection case 4 respectively by rearmounted photoelectric detector 9 and preposition photoelectric detector 11 has on the upper side, on the lower side with respect to optical axis, the situation of taking back, taking over, and the energy output signal, make the dead in line of light beam and light detection case 4 by the motion motor motion.In the case, can carry out the detection of passing beam, at first, under the dipped beam sense command effect of control system, light detection case 4 resets (returning to the original position), and tested headlamp transfers dipped beam to, this passing beam is after lens 6 are assembled, reflexed on the screen board 10 by half-reflecting mirror 7, when there is the certain deviation amount at the passing beam center, above-mentioned beam center will depart from screen initial point certain distance.Image pick-up device 8 is photographed the figure that is presented on the screen board 10, is sent to computing machine (being placed on the instrument outside), after computing machine carries out Flame Image Process, just can draw the passing beam of being examined easily and whether meet national standard.
