[0017] 1. The LED double high beam lens group provided by the utility model, since the universal seat is fixedly connected with the second support, the second support is fixedly connected with the first high beam lens group, therefore the first high beam lens group, the universal seat and the second support are integrally connected. When the ball head adjusting screw is rotated, the ball head adjusting screw will move along the axial direction, since the ball socket part of the universal seat is buckled with the ball head part of the ball head adjusting screw, the axial movement of the ball head adjusting screw will make the ball head part slide in the ball socket, so that the universal seat will be deflected, the deflection of the universal seat will drive the second support and the first high beam lens group to deflect integrally, the deflection of the first high beam lens group will cause the change of the projection direction and range of light, since there is a gap between the second support and the first support, the deflection of the second support can only deflect in the gap space, so the first high beam lens group can realize the adjustment angle of ±2°. The second high beam lens group is fixedly connected to the first support, and is irrelevant to the deflection of the second support, so the projection direction and range of the second high beam lens group will not change with the first high beam lens group, realizing the independent light adjustment of the first high beam lens group and the second high beam lens group, which is more convenient. In addition, taking the aiming of the second high beam lens group as the reference, if the first high beam lens group is in the state of not adjusting light, it may cause the light of the first high beam lens group and the second high beam lens group to be parallel, and two light spots appear, at this time, the ball head adjusting screw can be fine-tuned, the first high beam lens group is adjusted to the appropriate angle to coincide with the aiming reference of the second high beam lens group, so that the visibility of the scene far away is enhanced, and the interference of double light spots is eliminated, so that the illumination of the automobile headlamp to the scene far away is more in line with the observation habit of the driver, the flexibility of the driver's reaction to the obstacle far away is improved, so that various emergency reactions are made in time, and the occurrence of traffic accidents is reduced.

[0018] 2.

The axial movement of the first ball head adjusting screw will cause the first universal joint to deflect. At the same time, due to the sliding friction between the ball head of the second universal joint and the ball head of the second ball head adjusting screw, and the sliding friction between the ball head of the third universal joint and the ball head of the third ball head adjusting screw, the second bracket will drive the first high beam lens group to deflect up and down about the straight line formed by the second ball head adjusting screw and the third ball head adjusting screw as the axis, so as to change the projection direction and range of the first high beam lens group and align it with the aiming of the second high beam lens group, thereby increasing the high beam intensity and avoiding the interference of the dual beam spots of the first and second high beam lens groups. If it is necessary to adjust the first high beam lens group forward and backward, the third ball head adjusting screw can be rotated. The axial movement of the third ball head adjusting screw will cause the third universal joint to deflect. At the same time, due to the sliding friction between the ball head of the second universal joint and the ball head of the second ball head adjusting screw, and the sliding friction between the ball head of the first universal joint and the ball head of the first ball head adjusting screw, the second bracket will cause the first high beam lens group to deflect forward and backward about the straight line formed by the first ball head adjusting screw and the second ball head adjusting screw as the axis, so that the projection direction and range of the first high beam lens group are changed and coincide with the aiming of the second high beam lens group.
