The specific embodiment

From Fig. 1,2 as can be seen, supporter 1, rotating shaft 3, axle sleeve 4, head lamp 2, retracing spring 5, angular adjustment are adorned 8 relative position relation in the utility model.

Fig. 4 demonstrates orthodox car and turns to illuminating effect when travelling night, and as seen from the figure, the direction of illumination of head lamp is not with front-wheel deflection, so illuminating effect lags behind during front-wheel steering.

5,6 couples of embodiment of the present utility model are described further below in conjunction with accompanying drawing:

In the present embodiment, it is to be made of steel wire cover and the seizing wire 10 that is through in the cover that angular adjustment adorns 8, and an end of steel wire cover is fixed on the vehicle frame, and another rapids is fixed on the diagonal position supporter 1 of the present invention; One end of steel rope 10 is fixed on the steering trapezoidal arm of front-wheel, and another rapids is fixed on the spherical Connecting jont 7 of lamp tail of diagonal position head lamp.As can be seen from the figure, when automobile is kept straight on since the spherical Connecting jont 7 of head lamp afterbody under the effect of retracing spring 5 be fixed in supporter 1 on baffle plate 6 contact and steel rope 10 does not stress, the direction of illumination that makes head lamp 2 is the dead ahead.When the automobile left-handed turning to the time (as Fig. 6), make corresponding steel rope 10 pressurizeds and bending because the angle of tie rod arm changes (in this example in the counterclockwise direction) left tie rod arm, the spherical Connecting jont 7 of right side head lamp afterbody under the effect of retracing spring 5 be fixed in baffle plate 6 on the supporter 1 and keep in touch before the direction of illumination maintenance just of light; And right tie rod arm makes corresponding steel rope 10 tensions, head lamp afterbody spherical Connecting jont 7 in left side is also rotated to anticlockwise direction by the pulling force that steel rope 10 pullings overcome retracing spring 5, and the rotation angle and the angle of tie rod arm be varied to direct ratio, reached in advance turn-around zone carried out illumination purposes.When the automobile right-hand turning to the time, then the left side head lamp keeps to the dead ahead irradiation, the right side head lamp is deflection to the right then, and right side area is thrown light on.Fig. 3 be when the automobile right-hand turning to the time, the right side head lamp is the situation of deflection to the right then.

The variation that the head lamp that the utility model is only controlled the turn side carries out irradiating angle is to throw light on to the dead ahead in order still to keep opposite side under the prerequisite that obtains good illumination in the turn side, increases illumination zone, improves the traffic safety degree.

The advantage of present embodiment is: can be easily transform the head lamp of existing car, shortcoming is: no matter daytime, head lamp all can be because of turning to of automobile changes angle in a manner described, therefore can shorten angular adjustment and adorn 8 and life-span of head lamp.

When automobile travels by day, ECU has to the turn sign of sending here to steering system and does not have the illumination sign of head lamp, torque motor 11 is not controlled, therefore do not produce moment on the torque motor, steel rope 10 is tension not, the spherical Connecting jont 7 of head lamp afterbody under the effect of retracing spring 5 be fixed in baffle plate 6 on the supporter 1 and keep in touch before the direction of illumination of light just keeps.

When automobile at night running and when opening head lamp, ECU not only obtains turn sign that steering system sends here but also the illumination sign that has obtained head lamp, thereby torque motor 11 is controlled, produce moment on the torque motor, the effect that overcomes retracing spring 5 by the spherical Connecting jont 7 of steel rope 10 pulling head lamp afterbodys makes head lamp along rotating shaft 3 rotations, and the angle that the turns to moment of electric motor with large torque output more is big more, the pulling force that steel rope is produced is big more, the deflection angle of head lamp light is big more, and therefore the deflection angle and the front-wheel steering deflection angle of irradiation are proportional.

Equally, in order to increase illumination zone, improve the traffic safety degree.The head lamp that present embodiment is also only controlled the turn side carries out the variation of irradiating angle and keeps opposite side throwing light on to the dead ahead.

The advantage of present embodiment is: head lamp is just worked so the life-span is long, and the utility model controlled by ECU with turning to when working simultaneously the utility model, and its work automatically, reliably.
